Some strategic aspects of animal protein production
11-19Views:300The access to food shaped human societies and dietary models throughout the history of mankind. Animal protein consumption became a part of human culture. Data are presented showing the relationship of daily calorie and animal protein consumption as affected by capita GDP changes. Examples are presented how genetic improvement of animal and fodder plants influenced the resource efficiency and the overall environmental footprint per unit product. The two examples presented are: the dairy industry of the USA the 1944 and 2007 situation, and the Hungarian broiler chicken sector considering data relevant to 1930, 1960 and 2010. In both cases, dramatic improvements in resource efficiency could be demonstrated. The agricultural area required to animal feed production was reduced by more than 80% in both cases per unit product. Future possibilities are briefly discussed, referring to the still unutilized land reserves of the Globe, the new evolving technologies in progress inclusive the CASPR/Cas 9 genetic editing methods.

The initial steps of the black grouse repatriation
63-68Views:290The black grouse in Hungary is an extinct but a native and protected species now. In the 19th century, they used to be common in the so called Nyírség, the North-Eastern part of the Hungarian Great Plains.
The project to re-patriate black grouse was started in 2005 by the Nyírség Company of Forestry. We studied the conditions of keeping and breeding black grouse from German and English specialists and we endeavoured to expand our breeding population in 2007.
We also started to make a database of the whole bird stock, containing biometrical data from every individual specimen and data about the eggs (weight, length, width) and nestlings (weekly weight growth). In the future, we will continue our work to breed black grouse and re-patriate the new offspring, which will be nearby wild populations in a similar bio-geographic environment. In a few years it is hoped we will be able to accomplish a wild population in a natural habitat. Our work is now to breed these birds in captivity – similar to their natural habitat – prior to their release into the wild, in order to preserve biodiversity for our descendants through re-patriating black grouse here in Hungary as well. -
The effect of drought and cropping system on the yield and yield components of maize (Zea mays L.)
51-53Views:295Different Cropping Systems have many advantages and ensure better crop growth and yielding. Its combination with other agronomic measures can ensure optimal crop density for maximum crop growth and photosynthesis efficiency. The aim of this study was to investigate the influence of different cropping systems on monoculture and biculture rotations [maize- wheat]. The study found that crop rotation does not have a significant effect on the grain nutrition quality, Leaf Area Index (LAI) and Normalized Difference Vegetative Index (NDVI) but has a significant effect on the Soil-Plant Analysis Development (SPAD). Yield and yield components were significantly influenced by crop rotation in this study as yield, plant height, cob weight and number of grains per row all recorded lower mean at 5% probability levels.

Effect of sufficient and deficit irrigation with different salt inputs on the yield of cucumber
19-25Views:317Soil salinisation is considered one of the major environmental hazards threatening agricultural productivity and can be accentuated by climate change as well as the use of low-quality water in irrigation. This is the case in our study area which is affected by secondary salinisation due to the use of saline irrigation water for horticultural production. Deficit irrigation technique is implemented especially in arid and semiarid regions due to its potential to optimise water productivity while maintaining or increasing crop yield. The main objective of this study was to compare the effect of irrigation with sufficient (SD) and deficit (DD) doses. This research was carried out in Karcag in 2020. Cucumber was grown on a meadow chernozem soil and was irrigated with SD and DD of two irrigation water qualities. Soil moisture was monitored and crop yields were recorded. Despite the differences in quality and quantity of water, the application of less water by DD maintained the same yield as SD. We found a non-significant difference between the average soil moisture contents under the treatments (15.5 v/v% for SD and 13.5 v/v% for DD). Deficit irrigation can be an efficient technique due to its potential for improving water use efficiency, maintaining sufficient soil moisture content favourable for proper crop development and yield.

The study of environment-conscious attitudes in the food-industry companies of the Northern-Plain Region
155-163Views:176that the world of business, profit and work is not a hermetically closed area, but is in interaction with its closer and wider surroundings, ultimately with society and the natural environment.
The affectedness of each sector and company varies. To be able to tackle these problems, first and foremost the commitment of companies towards environmentally conscious attitude is necessary, which can form as a result of inner obligation or outer pressure. Thus companies will be concerned to measure and quantify the environmental effects of all activities.
Some of the companies have already given their votes for environment-protection. Both internationally and at home it seems that the responsible leaders of more and more companies build social, human rights and environmental protection considerations in the objects and values of the company apart from profit maximization.
In my thesis I present the data gathered from a questionnaire survey carried out with food-industry companies in the Northern-Plain Region. The aim of the survey was to evaluate the commitment of companies towards environmental protection via solid data. The fact that more than half of the respondents found the positive effects of environmental protection of little importance and that environmental protection was the last among the aims of some companies reflected greatly in the following outcomes. -

Investigation of the decomposition and leaching dynamics of Salix, Populus and mixed leaves in the area of Lake Balaton and Kis-Balaton Wetland
119-124Views:364In lakes and wetlands, leaf litter input from the coastal vegetation represents a major nutrient load and plays a basic structural and functional role in several ecosystems. In Hungary, at the banks of lakes and wetlands, Salix and Populus trees are the most common species. In an experiment in Lake Balaton and Kis-Balaton Wetland between 16 November 2017 to and 3 June 2018, the decomposition rates and leaching dynamics of Salix, Populus and mixed leaves (50% Salix and 50% Populus) were investigated. Total nitrogen and phosphorus content of biomass samples were measured at the beginning and end of the experiment for the leaching dynamics experiment. We found that litter mass losses (Salix, Populus and mixed leaves) were not significantly different between the two mesh size litterbags and between Lake Balaton and Kis-Balaton Wetland. Different amounts of the total nitrogen and phosphorus leaching from Salix, Populus and mixed leaves were detected. The total nitrogen contents of the plant samples were around 8-18% at the end of the investigated period. Slightly higher values were measured compared to phosphorous (27-29%).

Long-term effect of soil management on the carbon-dioxide emission of the soil
515-527Views:314CO2 emission from soils is one of the most important elements of the global carbon cycle, thus it has crucial rule in climate change. Each soil cultivation operation intervenes in the microbiological life of the soil, hence tillage is a factor through that the processes taking place in soil can be controlled. During the last decades, the organic material content of agricultural soils decreased to the half due to the intensive management resulting in the degradation of natural soil fertility. While intensive, plough-based tillage can cause soil degradation and erosion, the physical, chemical and biological status of the soil can be significantly improved through the application of conservation tillage methods. The results of long-term experiments prove that soil protective tillage enhances the enrichment of organic matter in the top layer of the soil. In order to reveal the role of tillage systems in CO2 emission from the soil, regular measurements were carried out in the plots with conventional and reduced tillage of the soil cultivation experiment of Research Institute of Karcag. Anagas CD 98 and Gas Alert Micro 5w infrared gas analysers were used to measure CO2-concentrations, and a specially developed method (consisting of a frame and a bowl) was applied to delimitate the measuring area. Most of the measurements were done on stubbles after harvest in order to exclude root respiration. The weather conditions of the examined 10 years were very changeable providing a good chance to compare them to each other. We found the tillage operations resulting in higher emission values in both tillage systems. On stubbles higher and more even emission was characteristic to reduced tillage due to the lower degree of soil disturbance and higher soil moisture content.

Evaluation of reduced tillage technologies in corn production based on soil and crop analyses
47-54Views:598Despite new cultivation methods, the proportion of conventionally cultivated land is still very high in Hungary.
Although these technologies demand more time, labour and fuel, they are still attractive to users because they require less professional skill and simple machinery. In Hungary, conventional tillage methods usually lead to soil deterioration, soil compaction and a decrease in organic content. These side effects have caused gradually strengthening economic and environmental problems.
The technologies for those plants which are dominant on Hungarian arable lands use (winter wheat, maize, sunflower and barley) need to be improved both in the interest of environmental protection and the reduction of cultivation costs.
The Department of Land Use at Debrecen University is cooperating with KITE Sc. to carry out soil tillage experiments at two pilot locations to prove tillage technologies already used in the USA.
The aim of our examination is to adapt new technological developments and machinery, and to improve them on Hungarian soil for local environmental conditions. With these improved machines, the field growing of plants could be executed by less manipulation and better suited to economic and environmental needs. The most significant task is to investigate and improve the conventional cultivation replacing, new soil-protecting tillage technologies, and to apply no-till and mulch tillage systems.
On the basis of the experiments’ survey data, we established that the looseness and moisture content of the soil using reduced tillage is more favourable than after using conventional technologies. The results of no-till and shallow spring tillage are behind those of winter plough or disk ripper cultivation in corn yield and production elements.
To preserve moisture content in the soil, the ground clearing and sowing while simultaneously performing no-till method presents the most favourable results. The surplus moisture gained using no-till technology is equal to 40 mm precipitation.
Regarding the yield of winter wheat we established that the tillage methods do not affect plant yield. Both disk ripper and conventional disc cultivation showed nearly the same harvest results (5.55 or 5.5 t/ha), where the difference is statistically hardly verifiable from the no-till method. From the individual production of corn and the number of plants planted in unit area, calculated results prove that no significant difference can be detected between the production of winter plough and disk ripper technology. Although the yield achieved with the no-till method is less than with the previously mentioned technologies, the difference is only 9-10%. We received the lowest production at shallow spring tillage.
Evaluations have shown a 1.1 t/ha (13%) difference in the yield of maize, between winter tillage and the disk ripper method, in this case the traditional method resulted in higher yield. In winter tillage, the yield of maize was 1.9-2.1 t/ha (23-25%) higher than in the case of direct sowing and cultivator treatments. No significant difference could be noted between the yields of direct sowing and cultivator treatments.
Our research so far has proved the industrial application of reduced tillage methods in crop cultivation technologies. -
Self Pollination and Fruit Quality-Comparative Research of Sweet Cherry Cultivars
295-299Views:273In fruit production – among stone fruits – sweet cherry is considered to have great promise, but species of sweet cherry need improvement. Cherry plantations are advanced in years, therefore putting into operation high productivity plantations is an important field of research. Through clonal selection and cross-breeding, several new cherry species were created in the recent past in Hungary. Spread of these species is also important. In our factorial cherry production, we use high trunk trees and trees with large crowns. Intensive plantations are very few in number.
Our goal is to study the morphological and physiological properties of new sweet cherry cultivars. The most important aim is to combine the productive area of foliage and the fruit quality. The present study shows the self pollination, fruit setting and fruit quality parameters. -
Analyzing the Population Retaining Ability and the Ability to Economically Provide for a Population in the Micro Region of Püspökladány
210-219Views:170According to the data of population density, 98% of Hungary’s territory has rural features. Gaining EU supports, in order to focus on developing the most underdeveloped communities, and in order to decrease – not to increase – the differences between communities, the establishment of priorities and determination of the rank of rural communities based on their development potential is necessary. The claim of measurability arises because of comparison and classification. A possibility or a target area of measuring is analysing population retaining and income producing capability of rural areas.
To gain adequate, many-sided information about the development potentials of a given community, micro- or macro region, complex condition survey, as well as secondary information completed with empirical data and subjective value judgment is essential. The aim in every case is to gain experience of the present condition via determining the direction of change.
In this study, I deal with the clarification of the definition of population retaining ability and the ability to economically provide for a population and introduce the most important results of the inquiry with questionnaires completed in the frame of an empirical survey. -
Agronomical and economic evaluation of various cultivation systems on meadow soil
103-106Views:210The requirements and objectives of cultivation are in constant change. There are different cultivation aims if the objective is soil protection, the prevention of its moisture content or on areas with different precipitation supply or production site endowments. Based on the experimental database of the Institute for Land Utilisation, Regional Development and Technology of the University of Debrecen, Centre for Agricultural and Applied Economic Sciences and the KITE Plc., the various cultivation systems in Hajdú-Bihar country were examined with maize as indicator plant. The sample area can be found in the outskirts of Biharnagybajom on meadow soil. On the examined plot, spring strip basic cultivation, loosening and autumn ploughing were applied on 15-15-15 ha, respectively. At the time of taking undisturbed soil samples, soil conductivity measurements were also performed with a Penetronik penetrometer. Undisturbed soil samples were taken from each treatment before sowing (on 5th April 2012). The yield obtained in the strip cultivation treatment increased that of the ploughing and the loosening technology. The economic indexes are the most favourable in the strip cultivation.

Effect of the media on morphology of Cryphonectria parasitica (Murr.) Barr isolates and their Vegetative Compatibility Groups
38-42Views:477The most dangerous pathogen for the European and American chestnuts is the blight fungus Cryphonectria parasitica (Murrill) Barr. Short after its introduction a big number of chestnut trees were destroyed on the infested area. The control could be really complicated, because of the numerous vegetative compatibility groups of the fungus. There is a type that carries a mycovirus viz. hypovirus in the cytoplasm. We are able to control effectively this pathogen by using mycovirus-carrying strains (called hypovirulent fungal strains also). In laboratory it is easy to multiply the virulent and the hypovirulent strains of the fungus but do not easy to differentiate colonies visually on simple PDA medium. During our research, we tested different types of media, based on potato and chestnut bark extract respectively. It was observed that on potato medium the virulent strains produce more orange pigments. So it is more easy to differentiate virulent or hypovirulent isolates of chestnut blight fungus based on colony colour and morphology.

Effect of Silver willow “Russian olive” (Elaeagnus angustifolia) on extensive sheep management
157-162Views:220We carried out a study in the Karcag Research Institute, which affected the areas of narrow-leaved silver willow. In the framework of this research, we performed Balázs's coenology, and thus established the degree of Borhidi degradation, which resulted in the fact that the areas of the silver willow were degraded practically irreversibly, the diversity of the grassland has decreased. We consider it very important to study these grassland areas of silver willows, as they can provide an additional fodder base for sheep grazing, which will also increase the sustainability of the grassland. The obtained soil analysis results show that the soil samples of the silver willow areas are richer in nitrogen (p-value: 0.006) and phosphorus (p-value: 0.003) than the examined control area.

Examination of Zn deficiency on some physiological parameters in case of maize and cucumber seedlings
5-9Views:212Zinc (Zn) is an essential micronutrient needed not only for people, but also crops. Almost half of the world’s cereal crops are deficient in
Zn, leading to poor crop yields. In fact, one-third (33%) of the world's population is at risk of Zn deficiency in rates, ranging from 4% to
73% depending on the given country. Zn deficiency in agricultural soils is also a major global problem affecting both crop yield and quality.
The Zn contents of soils in Hungary are medium or rather small. Generally, the rate of Zn deficiency is higher on sand, sandy loam or soil
types of large organic matter contents. High pH and calcium carbonate contents are the main reasons for the low availability of Zn for
plants (Karimian and Moafpouryan, 1999). It has been reported that the high-concentration application of phosphate fertilisers reduces Zn
availability (Khosgoftarmanesh et al., 2006). Areas with Zn deficiency are particularly extensive in Békés, Fejér and Tolna County in
Hungary, yet these areas feature topsoils of high organic matter contents. Usually, Zn is absorbed strongly in the upper part the soil, and it
has been observed that the uptakeable Zn contents of soil are lower than 1.4 mg kg-1.
Maize is one of the most important crops in Hungary, grown in the largest areas, and belongs to the most sensitive cultures to Zn
deficiency. Zn deficiency can causes serious damage in yield (as large as 80 %), especially in case of maize. On the other hand, Zn
deficiency can also cause serious reduction in the yields of dicots. One of the most important vegetables of canning industry is cucumber,
which is grown all over the world.
In this study, the effects of Zn deficiency have investigated on the growth of shoots and roots, relative and absolute chlorophyll contents,
fresh and dry matter accumulation, total root and shoot lengths, the leaf number and leaf area of test plants in laboratory. Experimental
plants used have been maize (Zea mays L. cv. Reseda sc.) and cucumber (Cucumis sativus L. cv. Delicatess). A monocot and dicot plant have
chosen a to investigate the effects of Zn deficiency, because they have different nutrient uptake mechanism.
It has been observed that the unfavourable effects of Zn deficiency have caused damage in some physiological parameters, and
significantly reduced the growth, chlorophyll contents of monocots and dicots alike. -
Investigations on Mud on Heavy Metal Contaminated Flood-Plain of Tisza
96-101Views:788At the beginning of the year 2000 subsequently to a mine accident high heavy metal content mud entered the catchment area of the Tisza and was transported through the whole Hungarian section of the river. The majority of the heavy metals had been bounded to the floating sediment that was deposited on the flood-plain soil during flood forming a new, 5-10 cm thick layer. In the mud samples collected after the flood there was a clearly visible dark grey layer with significantly higher heavy metal content that was formed by the pollution wave and it was sorruonded by a light layer. The upper layer of flood-plain soils are formed from this mud layer during the soil development process, so the amount of Lakanen-Erviö soluble heavy metals that correlate with bioavailable heavy metal content was examined as well. In this case only the lead content was significantly higher in the dark layer.
New mud samples were collected after the 2001 flood. Separate layers could not have been identified, their colour was similar to those of the previous year’s light layers’. Comparing to this light layer the total Zn and Lakanen-Erivö soluble metal content was significantly lower in the mud samples of the year 2001. While the proportions of total and Lakanen-Erviö soluble metal concentrations were equal in both of the layers regarding the elements, these ratios have significantly changed next year regarding Pb and Zn: the amount of Lakanen-Erviö soluble metals considerably decreased.
As a result of sequential extraction the heavy metal content was rather low in the water soluble and exchangeable and NaOH-soluble fractions, so heavy metals found in the mud could be released in greater amount only in case of a heavy acidification. -
Situation of small and middle sized enterprises in Northern Great Plain Region
69-72Views:233Most of the enterprises operating in Hungary belong to the group of small and medium enterprises (SMEs) which means that their total number of staff is less than 250. The aim of the study is to examine SMEs operating within the North Great Plain region. It provides a short summary of the general characteristics of the region, the situation and significance of SMEs based on the data 2009 and it also clarifies the relevant definitions. The data shows that the enterprise type that is most characteristic in the the region is joint venture (the most popular type is Ltd). It can be laid down as a fact that the number of micro and sole entrepreneurs is also significant in the area. It is also clear that the majority of small enterprises deals
with commerce, while most of the medium enterprises are involved in industry (processing industry). As a continuation of the examination, size of investments, influx of foreign capital, ratio of employed people and grant opportunities are also to be evaluated since these factors influence the operation of enterprises as well. -

The effects of drought stress on soybean (Glycine max (L.) Merr.) growth, physiology and quality – Review
19-24Views:428Abiotic stresses are one of the most limiting factors inhibit plant's growth, leading to a serious production loss. Drought stress is one of the most destructive abiotic stresses and is still increasing year after year resulting in serious yield losses in many regions of the world,
consequently, affecting world’s food security for the increasing world population. Soybean is an important grain legume. It is one of the five major crops in the world, an essential source of oil, protein, macronutrients and minerals, and it is known as the main source of plant oil and protein. Harvested area of soybean is increasing globally year after year. However, soybean is the highest drought stress sensitive crop, the water deficit influences the physiology, production and seed composition of this crop. We introduce a review for literatures concerning the changes of the above traits of soybean exposed to drought stress, with past explanations for these changes. -
The roles of mycotoxins in cereal crops production: A comparative study of Hungary and Tanzania
151-159Views:745Although Hungary and Tanzania's climatic, soil, and technological conditions differ significantly in crop production, cereals crop cultivation is of paramount importance; maize crop dominates the cultivated area (Hungary 1 million ha, Tanzania 3 million ha) both from a feed and food point of view. Unfortunately, in both countries, fungal species (Fusaria, Aspergilli, Penicillia, etc.) that produce various mycotoxins on cereals, including maize grains, are a growing concern. The situation is complicated because these fungal species and their toxins can appear not only on cereals but also on other crops. Despite the prevalence of mycotoxins in both countries, studies show higher exposure risks and contamination above tolerable levels for human consumption in Tanzania to Hungary, with Tanzania observing acute aflatoxicosis.

Measurement of the degradation of abandoned turf
145-149Views:343With the decreasing number of grazing livestock in Hungary, the role of the turf cultivation is also significantly decreasing. The proportion of the under- and non-utilized turf is increasing. In the research conduced at the University of Debrecen, IAREF Research Institute Karcag, we studied four types of turf utilization in three replicates on a salt field with timothy grass. We determined the flora composition of the experimental area, measured the soil moisture and the carbon-dioxide content of the soil.

Possibilities of Corn Seed Commercialization on the Hungarian Market in 2003
166-169Views:197According to the sales results of the past two years we can draw the conclusion that although the Hungarian hybrids have very good capabilities, they are still in a big disadvantage in the corn seed sales sector, considering other foreign varieties. These above mentioned disadvantages, as published in prior essays, are not because of the variety’s low quality, but the lack or little presence of marketing. In order to gain position and market on the seed sales sector in Hungary, a lot more has to be done in the area of advertisement.
Seed advertising is very particular and different from all other types of goods. To make growers familiar with your product, you have to be in continuous contact with them, through field days, exhibitions and presentations, besides the well known and in other areas also used quotidian advertisement methods.
Although Hungarian breeders reach better and better results each year, they still cannot catch up with the multinational companies spending millions of dollars on development and advertising, thanks to their financial position.
Finally we can state that choosing the appropriate variety for our needs and possibilities of land and machinery is of great importance in order to reach the best results we can. -
The electronic claiming for the Single Area Payment Scheme (eSAPS) in Hungary: the evaluation of a new system
61-68Views:207The agricultural subsidies play a crucial role in the policy of the European Union. Remarkable part of the EU budget is dedicated to agriculture and rural development. The enlargement of the EU, the global changes in the market and other challenges are raising the demand for a better and more efficient way of work in the organization, using information and communication technologies, and especially the implementation of e-government
services. The article presents the Hungarian electronic claiming system (called eSAPS) for European founds in agriculture, and evaluates the first year of its operation. -
Effect of agrotechnical factors on the yield of the Grolim asparagus (Asparagus officinalis L.) hybrid on acidic sandy soil
43-48Views:519Research of blanched asparagus has begun at the University of Debrecen Institutes for Agricultural Research and Educational Farm Research Institutes of Nyíregyháza in 2011. Establishment of the plantation took place in May 2011. The Grolim hybrid was used in the trial, 16 medium plot trial area has been formed under field conditions, with four repetitions and 36 m2 plot size. In the course of our studies, the effect of different nutriment supply methods (untreated, manure, sheep manure compost, fertilizer) has been analysed on the spear yield of the Grolim asparagus hybrid between 2013 and 2017.
In our studies, the beginning of vegetative growth has been recorded upon the constant presence of 10 °C of average soil temperature in the case of the Grolim asparagus hybrid. The beginning and length of spear harvesting are both influenced by the time and dynamics of initial development in spring. During the analysed period, the dates of spear harvesting were various, the earliest being on 23rd March, 2014 and the latest on 23rd April, 2015; the rest of the three years have been varied within this one month interval. The total of heat units required for the vegetative development of spears has been determined; it provides important information for cultivation practice.
Spear yields turned out to be hectic during the analysed period. In 2013 and 2014, yields have surpassed the amount of 50 kg/harvest period/plot in the case of every treatment version. However, in 2015 a significantly lower specific yield has been recorded due to the unfavourable weather conditions in spring; a yield decline of nearly 50% was recorded in the case of the control treatment compared to the previous years. Yield was also lower in the rest of the fertilization treatments compared to 2014; however, in these cases, the degree of yield decrease was around 5–10%, which suggests the yield stabilising effect of fertilization. In 2016, a slight yield increase was measured in comparison with the base year. In 2017, there was a decline of yield in the control treatment; however, the different fertilization treatments resulted in yield increase as compared to previous years.
On the basis of our studies, it is clear that the best yield results have been provided by the artificial fertilization treatment in all of the five analysed years. It was followed by the sheep manure compost and manure treatments in terms of their effect on spear yield. During the three harvesting periods, the lowest yield on acidic sandy soil was recorded in the case of the control treatment. The most remarkable effect of nutriment treatments has been realised in terms of the decreased deviation of yield results, which perfectly represents the yield stabilising effect of nutriment supply in the case of perennial crops – asparagus – as well, even on a poor nutriment supply characteristic sandy soil.

The influence of primary soil tillage methods and foliar nutrient provision on the growth, yield, and associated traits of winter barley (Hordeum vulgare L.)
19-26Views:541Sustainable agricultural practices are vital for ensuring global food security. Factors such as soil, weather, and agronomic practices, including nutrient supply and tillage systems, play key roles in sustainable crop production. A field experiment at the Hungarian University of Agriculture and Life Sciences in Godollo, Hungary, assessed the impact of primary soil tillage methods and foliar nutrient supplementation on winter barley yield and traits. Using a split-plot design with three replications, the study examined four nutrient treatment (control, Bio-cereal, bio-algae, and MgSMnZn Blend) and two tillage methods (plowing and cultivator). The obtained results indicated no significant influence of tillage treatments on SPAD value, leaf area index (LAI), plant height, or spike length. However, nutrient treatments significantly (P<0.01) affected LAI, plant height, and thousand kernel weights. Both nutrient and tillage treatments significantly (P<0.01 and P<0.05) influenced tiller number and grain yield, with significant (P<0.01) interaction effects observed for grain yield and kernel weight. The combination of Bio-cereal nutrient treatment with plowing tillage produced the highest values across parameters. Thus, integrating bio-cereal nutrient supplementation with plowing tillage is better for optimizing winter barley yield.
