According 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.

All the research in Hungary and other countries in Europe focus on improving the quality of crops and increasing the competitiveness of production.
In this respect, we have to advance the conventional technological elements, reduce the application of pesticides and fertilizers, and produce new varieties suitable for environmentally-sound production. In our crop breeding programs, we applied conventional and biotechnological methods (embryo rescue and double haploid methods) in order to get somaclonal and gametoclonal variations.
We produced winter wheat lines (HP-31-95, HP-82-96) by traditional way, which have high baking qualities and high nutrient efficiency. Some diseases can limit the quantity and quality of a wheat crop. We examined several wheat diseases in our winter wheat candidates, and we found that our progenies have resistance to leaf rust.
With respect to a serious problem was the small quantity of applied fertilizers and the other externals, our research focused onto advance a common wheat selection system, with the help of it, we can handle these problems. We have summarized that our selected progenies can compete with the registered varieties with quality and environmental respect.

Application of fungicides have advantages and also some direct or indirect disadvantages, such as imbalance and/or fungicide resistance in microbe population. To avoid these problems the development of alternative, eco-friendly methods like mostly spraying with oils are in the focus nowadays. The investigations of the effects of fungicides on microbiota in some cultivations can give a more complex view to this topic and developmental possibilities. In the present study, our aim was testing of the effects of paraffine oil (as alternative fungicide) on microbial properties (CFU and rate of filamentous fungi and yeasts) of Chardonnay and Kékfrankos leaves and berries.

Our results from 2014 showed that the application of paraffine oil as sole spray agent can decrease the presence of saprophytic filamentous fungi on the berries of Chardonnay (susceptible for fungal infections). In the case of Kékfrankos berries opposite properties were observed, which may be the result of the absorption of oil by the thick wax layer of this variety. The oil treatment did not affect the yeast population of Chardonnay and Kékfrankos berries contrary to negative effect of the regular pesticide treatment. The selective fungicide effect of paraffine oil against filamentous fungal population caused the accumulation of yeast cells in the mycobiota of grape berries. The careful use of this yeasts in spontaneous fermentation can improve the aroma profile of wines. The year of 2015 did no prefer the growth of fungi, therefore no interesting properties were detected in the mycobiota of grape varieties. The occurence of the harmful saprophytic filamentous fungi predicted to be increased in mild climate agricultures as the result of the climate change.

In summary, the paraffine oils are seem to be promising tools for the eco-friendly control of harmful fungi of grapes.

The marketability of table grapes is mainly characterized by berry size, color, taste and texture. Mechanical measurements of table grape berries could provide objective information on the textural qualities of grape berries. In addition, this method might be suitable to study the effects of phytotechnical methods (such as girdling) on table grape quality. The aim of this preliminary work was to demonstrate how instrumental testing could be used to examine the effects of girdling on berry grape texture and define the textural characteristics of table grape berries. Cane girdling was carried out at veraison in two table grape varieties. Texture analysis was performed several times during the maturity. Besides this examination another five varieties were analyzed to assess their berry mechanical properties. Double compression test was used to determine berry hardness and its derived parameters. Puncture test was applied to evaluate skin hardness, skin elasticity and skin break energy. Skin thickness was also investigated. Berry hardness, skin hardness and skin thickness of the girdled grapevines were significantly affected by this technique. Most of the textural parameters showed differences among the seven cultivars.

On the basis of the operative French regulations, we qualified the alveographic qualification and the valorigraphic qualification respectively for each of the 10-14 winter wheat varieties grown each year between 2002-2005, and used in a field experiment at the Karcag Research Institute of the University of Debrecen. The field experiment at the Látókép Research Institute of the University of Debrecen allowed us to examine the alveographic and valorigraphic values of the samples of GK Öthalom and Fatima 2 winter wheat varieties taken from an 8 year period (1997-1999 and 2001-2005).
Throughout the experiments on samples from the Karcag Research Institute and Látókép Research Institute of the University of Debrecen, we tried to find whether the alveographic W value or the P/L value provides the safer method for the qualification of wheat samples, instead of the qualification commonly used in Hungary. We found that in terms of the samples from the Karcag Research Institute, the baking quality and the W value in each of the examined years, while in terms of the Látókép Research Institute, most of the years showed a close positive correlation, contrary to the close negative relationship between the baking quality and the P/L value. The correlation index varied depending on the year, the variety, and fertilizer doses, which require further examinations.

In the trade of the European Union principally the analysis of alveographical and extensographical parameters mean the acceptance system.
In the present study we analysed the extensographical parameters of 10 winter wheat varieties breed by the Cereal Research Non Profit Company with Brabender extensigraph and we made a comparison, correlation among the results. The examinations with Brabender the following among: show the GK Kalász and the GK Élet varieties show high resistance of extension and the GK Petur variety produces high extensibility. The GK Garaboly has shown low extensibility and energy. The other parameters had different values in the examined three years. The measurings with SMS2 Texture Analyser show middle positive correlation between extensibility and subarea. There are weak correlation between at the significantial level in the 90, 135 resistence of extension by Brabender and by SMS2 Texture Analyser and in the 45 extensibility by Brabender and by SMS2 Texture Analyser of relaxed dough. There is no correlation among other parameters. 

The disease syndrome caused by Waitea circinata, a soil-borne pathogen introduced in the past decade into Carpathian basin, visually indistinguishable of those caused by various Rhizoctonia strains in diverse host plant. Dicotyledonaceous species in general proved to be more tolerant to this new pathogen than monotyledonaceous ones. This mesophilic fungus can seriously damage cereals. The barley varieties, similarly to other plants, exhibited highly different individual reaction to soil borne infection, Bivoy being the most while Maresi the less tolerant among the 9 tested varieties. Two groups could be separated on the base of their response to Rhizoctonia; Jubilant, Bivoy, Pasadena formed one group being moderately tolerant and Anabell, Scarlett, Rex and Omega the other group of more susceptibles. Three significant factors influence on the virulence of Rhizoctonia strains comprised 62% of total variation.

New varieties and fertilization have significantly increased yields of maize in recent decades. It has to be taken into account however that the interactions and the balanced combination of cropping factors (ecological, biological and agrotechnical) are the main factors which determine yields. Weather conditions were rather unfavourable during the last decade. Extreme weather conditions occurred due to global warming; 6 of 10 years were plagued by drought. Consequently yields increased from 10-20% to 30-50%. In view of varieties the situation is advantageous, maybe the supply of hybrids is too high, nevertheless those hybrids need to be selected which are particularly well adjusted to the ecological conditions. Many technologies can be applied which vary according to intensity, but the balanced combination of cropping factors should be secured on the basis of the hybrid’s intensity. Among agrotechnical factors the compensation of nutrients and technological conditions were inadequate. These days farmers only use nitrogenous fertilizers consequently they significantly decrease the easily available P and K content of the soil which in long term leads to the deterioration of the soil’s productivity. The technological background is therefore important, because sufficient yields can only be expected if agrotechnical operations are carried out in the right time and quality. 

Nowadays the success vegetable and fruit production are unimaginable without regular nutrient management. One of the ways to supply the required nutrients in an environmentally friendly way is the application of composts, which is less widespread so far. Compost doses were applied in biological and integrated apple orchards in cooperation with the Institute of Horticultural Science in the years 2010 and 2011. Different changes were resulted by the compost treatments in the examined parameters in case of both apple varieties (Golden Delicious and Pinova). There is no clear effect of compost on the changes of ash-, total acids, Vitamin C and the sugar content until now, because the improvement of the nutritional indicators takes more time. However significant differences were observed after one year between the apple varieties. Higher ash-, total acids and sugar content were measured in case of the apple variety Pinova, while the measurements showed higher Vitamin C content in case of the variety Golden Delicious.

Our field researches took place on the Látókép test farm of Agricultural Science Centre of University of Debrecen, Centre for Agricultural and Applied Economic Sciences, in long-term experiment, on calcareous chernozem soil, in growing season of 2014/2015. In our experiment we examined the fertilizer reaction and the yield of different winter wheat genotypes (GK Öthalom, GK Csillag, Mv Csárdás, Mv Toldi) with grain maize and sweetcorn forecrops. According to our results, the sweetcorn forecrop strongly affected the yield. In the average of the fertilizer treatments and the varieties, after sweetcorn forecrop 6.9 t ha-1, after grain maize forecrop 5.4 t ha-1 average yield was gained. According to our data, the fertilizer reactions of the varieties were significantly different.

We analysed the crude protein content, amino acid content, amino acid composition of four forage and milling III. quality winter wheat varieties (Magor, Hunor, Róna and Kondor) from their samples from five following years (2003, 2004, 2005, 2006, 2007). We found that quantity of essential and non-essential amino acids rose with increase in crude protein content. On examination of protein amino acid composition in relation to crude protein content we found that the crude protein content increased the quantities of the non-essential amino acids also rose, while those of the essential amino acids decreased as the lysine, the limiting amino acid of wheat. We also established that, as crude protein content increased, the biological value of the protein decreased.

The aim of storage after harvest is to protect the quality of wheat, because after-ripening occurs in the first 5–6 weeks. During this time it very important to make the optimal storage conditions.

We have carried out storage experiment with wheat samples from Látókép Research Farm of the University of Debrecen. We analyzed the rheological parameters of Lupus and GK Csillag varieties from the crop year 2011/2012. The experiment period was between July and August 2012 (24. 07. 2012., 31. 07. 2012., 21. 08. 2012.).We determined the rheological parameters (water absorption, dough stability time and valorigraph quality number) of Lupus and GK Csillag during short term storage. Our results showed that after-ripening increased the baking quality of Lupus and GK Csillag during storage.

One of the remarkable effects of the economical and social development is the changing of the eating habits, first of all increasing consumption of deep-frozen products. The spreading of the sweet corn under these vegetables is characteristic.
The parameters exerting influence on the quality of the deepfrozen sweetcorn is classed in 3 categories:
• Physical quality: foreign matter, clumps, blemished corn, broken kernel, miscut, pulled kernel.
• Organoleptical features: taste, colour, texture, and sweetness.
• Microbiological features: TVC, mould, yeast.
The moisture content of the raw material influences the organoleptical features to the highest degree.
We take continuously samples from the raw material arriving in to the factory to determinate moisture content, and from the product to specify the organoleptical features.
Based on the data of 2002 we can make the following findings:
The colour of the deepfrozen sweetcorn is less influenced by the moisture content. The taste is between 69% and 72% the most optimal, but over 72% get worse, more „milky”, water-tasted because of the underdevelopment of sweetcorn. The texture continuously becomes better with the increasing of moisture content. Under 67% of water the class „C” is typical, which means a taste with weak charasteric, a bit scathing or bitter, and texture with rubbery inner part and hard pericarpia. The decadence of taste is caused by converting a great part of sugar into starch.
The correlation between moisture and quality is varying by varieties; different varieties have their best quality by different moisture content. By our investigations the best harvest time is at the 69-72% moisture content. At this point are the organoleptical features the most optimal, and the grower has not the loss of yield caused by early harvesting.

We analysed the crude protein content, amino acid content, amino acid composition of four forage and milling III. quality winter wheat varieties (Magor, Hunor, Róna and Kondor) from their samples from five following years (2003, 2004, 2005, 2006, 2007). We found that quantity of essential and non-essential amino acids rose with increase in crude protein content. On examination of protein amino acid composition in relation to crude protein content we found that the crude protein content increased the quantities of the non-essential amino acids also rose, while those of the essential amino acids decreased as the lysine, the limiting amino acid of wheat. We also established that, as crude protein content increased, the biological value of the protein decreased.

Variety testing including disease resistance test of the major crops has been carrying out since the 1960’s in Hungary. Testing for resistance of the new candidate varieties is performed in the so-called VCU (Value for Cultivation and Use) trials under natural infection and in special small-plot or micro-plot trials using different disease provocative methods. Disease resistance, especially those of multiple and horizontal-type (race non-specific, partial or durable) resistances, has recently become a key limiting factor in the state variety registration. The role of disease resistance in the decision-making process of variety registration is demonstrated on the examples of winter wheat and sunflower as two major field crops in Hungary.

An increasing interest has been observed of beetroot leaf as a salad component due to recent studies focusing on their nutritional value. The randomized field experiment was carried out on lowland chernozem soil with 6 varieties, 3 replications and 2 sowing dates. Sampling was performed on 23 of August 2018 at the stage of 30 and 50 days of vegetation, where leaf (30 and 50 days) and root (50 days) were collected. Total dry matter, folic acid and nitrate content were evaluated.

The results of this investigation show that higher total dry matter content was measured in the root (8.47–10.30%) compared to the leaf in both developmental stages (6.47–9.20%). Nevertheless, higher folic acid content was found in the young leaves of 30 and 50 days of development (58.77–113.86 µg 100g^-1). Among the examined varieties, Bonel has presented great amount of folic acid not only in the leaves (99.35–113.61 µg 100g^-1), but also in the root (89.99 µg 100g^-1). Finally, lower nitrate content was found in Libero (316.16 mg kg^-1) at 30 days and in Akela (340.41 mg kg^-1) at 50 days of development. Thereby, fresh consumption of beetroot leaves are highly recommended.

Although a high portion of domestic orchards is cultivated extensively, quality Hungarian sour cherry is a highly demanded product throughout Europe. Trees are slightly pruned, or not pruned at all. Thanks to the unique character of the species, older wood parts are pilling up. Thus, the interior of the canopy is inactive, fruits and shoots confine the exterior layer of the canopy.
We established pruning treatments in the sour cherry plantation in the Horticultural Exhibition Garden of the University of Debrecen, involving two age groups in two spacings. The trees are standing on seedling rootstock. The involved varieties were: Érdi bőtermő, Debreceni bőtermő and Kántorjánosi. We examined how to encourage shoot formation and the regeneration of older, pilling wood of the interior canopy parts.
Applying strong rejuvenating cuts, the most shoots were generated on the 3rd and 4th year laterals. Wood parts older than the 3rd year shall be removed by leaving short (2-3cm) stubs. This way, older, passive woodparts can also be made to burst out. From the examined varieties the Kántorjánosi showed the most favourable regenerative ability. Due to summer pruning, more shoots regenerated on the axis of the trees, than on those rejuvenated in the dormant season.

Some Egyptian rice genotypes [i.e. Japonica (Sakha 104), Japonica/Indica (Egyptian hybrid1) and Indica (Giza 182)] were investigated to evaluate the cooking and eating quality characters. High significant differences in grain shape were observed among rice genotypes. Hulling, milling and head rice percentage were higher in Sakha 104 than other rice genotypes, while Indica type (Giza 182) recorded the lowest values in milling and physical characters. No significant differences were found in chemical composition of the three genotypes of rice was recorded, but Giza 182 had the highest protein content. All Egyptian rice genotypes were low in gelatinization temperature and soft in gel consistency. Japonica and Indica rice varieties were low in amylase content, while Japonica/Indica rice variety was intermediate. The use of RVA is considered a good index for palatability evaluation for milled rice flour and starch. The Indica and Japonica/Indica types are low in breakdown viscosity, but higher in cooked pasta than Japonica type. Japonica type recorded the best score in panel test, followed by Indica type, while Indica/Japonica rice variety was the least accepted by Egyptian consumer.

Grain number per spike was studed in 6 winter wheat varieties and all their 30 direct and reciprocal F1 hybrids. Parents
included 4 released Romanian variety, the old american Atlas 66 and a dwarf breeding line, Oradea 79. This line has a low number of
grains/spike, but is important in breeding program for here reduced height. General and specific combining abilities were computed and
genetic effects were estimated using Griffing’s method 1, model 1, as modified by Cabulea (1983).
For this diallel crosses, gene interactions and the interaction between cytoplasm and nuclear genes were highly significant and
the ratio of additive and non-additive effects was close to one.
The variety Fundulea 29 showed the highest general combining ability and it is recommended as a good parent for increasing
grain number/spike. Mid-parent heterosis was significant in 9 out of the 30 cases, mostly in hybrids involving the breeding line Oradea 79.
In 3 cases the number of grains/spike of F1 hybrids was significantly lower than the average of the parents. The breeding line Oradea 79 had
a significant negative general combining ability, but showed significant positive specific combining ability in most crosses, as well as a
significant positive effect of its cytoplasm. These results are considered to indicate that there are chances of improving the grain
number/spike in some crosses with Oradea 79.

We did the detailed agronomy examination and assessment of sweet corn cropping technology by analysing the data of TONAVAR Ltd. The Ltd. developed a special sowing construction which is based on band application of main sowing and double growing. In main sowing they use super sweet hybrids, and in double growing they use normal sweet varieties. In double growing sugar peas and the sweet corn can be cultivated together successfully. In every two years appearing sugar peas has a good effect on the sweet corn growing in monoculture. At the same time
the long-term successfulness of this questionable onto the illnesses of the peas because of the considerable sensitivity.
According to our examinations in main sowing the optimal period is between May 1. and 30., and in double growing the optimal period of sowing is between June 1. and 20. The optimal plant density is different too for the two sowing time. For super sweet hybrids the optimal plant number is 60-63 thousand/ha and for the normal sweet that is 65 thousand/ha.
Our examinations show that soil pest (defence with soil sterilisation in sowing time), Diabrotica virgifera, Helivoverpa armigera, Ostrinia nubialis are the greatest danger for the sweet corn quantity and quality.
The use of herbicides is the most efficient in the postemergens in main sowing and preemergens in second crop.
Our examination shows that the efficient sweet corn growing cannot be imagined without irrigation. The most efficient irrigation is in main sowing in the critical fenophase of crop time. In double growing the initial irrigation, and the crop irrigation are the most efficient. Based on the production data verifiable that beside the application of the discribed growing technology in the 2005-2007 years the average yield was 20,9t/ha of main sowing, and 17,8t/ha of second crop on chernozem soil in the Hajdúság. 

Nanotechnology is highly interdisciplinary and important research area in modern science. The use of nanomaterials offer major advantages due to their unique size, shape and significantly improved physical, chemical, biological and antimicrobial properties. Physicochemical and antimicrobial properties of metal nanoparticles have received much attention of researchers. There are different methods i.e. chemical, physical and biological for synthesis of nanoparticles. Chemical and physical methods have some limitations, and therefore, biological methods are needed to develop environment-friendly synthesis of nanoparticles. Moreover, biological method for the production of nanoparticles is simpler than chemical method as biological agents secrete large amount of enzymes, which reduce metals and can be responsible for the synthesis and capping on nanoparticles.

Biological systems for nanoparticle synthesis include plants, fungi, bacteria, yeasts, and actinomycetes. Many plant species including Opuntia ficus-indica, Azardirachta indica, Lawsonia inermis, Triticum aestivum, Hydrilla verticillata, Citrus medica, Catharanthus roseus, Avena sativa, etc., bacteria, such as Bacillus subtilis, Sulfate-Reducing Bacteria, Pseudomonas stutzeri, Lactobacillus sp., Klebsiella aerogenes, Torulopsis sp., and fungi, like Fusarium spp. Aspergillus spp., Verticillium spp., Saccharomyces cerevisae MKY3, Phoma spp. etc. have been exploited for the synthesis of different nanoparticles. Among all biological systems, fungi have been found to be more efficient system for synthesis of metal nanoparticles as they are easy to grow, produce more biomass and secret many enzymes. We proposed the term myconanotechnology (myco = fungi, nanotechnology = the creation and exploitation of materials in the size range of 1–100 nm). Myconanotechnology is the interface between mycology and nanotechnology, and is an exciting new applied interdisciplinary science that may have considerable potential, partly due to the wide range and diversity of fungi.

Nanotechnology is the promising tool to improve agricultural productivity though delivery of genes and drug molecules to target sites at cellular levels, genetic improvement, and nano-array based gene-technologies for gene expressions in plants and also use of nanoparticles-based gene transfer for breeding of varieties resistant to different pathogens and pests. The nanoparticles like copper (Cu), silver (Ag), titanium (Ti) and chitosan have shown their potential as novel antimicrobials for the management of pathogenic microorganisms affecting agricultural crops. Different experiments confirmed that fungal hyphae and conidial germination of pathogenic fungi are significantly inhibited by copper nanoparticles. The nanotechnologies can be used for the disease detection and also for its management. The progress in development of nano-herbicides, nano-fungicides and nano-pesticides will open up new avenues in the field of management of plant pathogens. The use of different nanoparticles in agriculture will increase productivity of crop. It is the necessity of time to use nanotechnology in agriculture with extensive experimental trials. However, there are challenges particularly the toxicity, which is not a big issue as compared to fungicides and pesticides.

Plant and ear height are very important characters not only for describing new varieties of maize (Zea mays L.), but for green and dry matter production, and even for grain yield. Significant positive correlations have been reported by various authors between plant height and stover yield, plant height and dry matter yield, and plant height and grain yield. The height of the main ear is also correlated to plant height. It depends on the variety or the environment, but is likely to be the same height within a population. Many environmental and agronomical factors (e.g. plant density, fertilization, pests and diseases) influence the expression of these characters, which are not quality traits. Their expression is controlled by many genes and by the interactions between these genes. The heritability of these traits is high and they show significant genotypic variability and positive heterosis, as reported in many research publications.

Our experiments were carried out during 2009 and 2010 years on Szépmező field, next to the Sepsiszentgyörgy town, Kovászna county, Romania. The experimental area situated at 520 - 580 m altitude, its soil is a humus rich chernozem, the yearly average temperature is between 7 - 8 oC, the precipitation is 500 - 600 mm/year. 7 different fungicides efficacy were studied for control to potato late blight disease caused by Phytophthora infestans on three potato varieties, viz. Ostara, Santé and Desirée.

In the laboratory the fluanizam (500 g/L, ALTIMA 500) fungicide was the best in inhibition of growing fungus while on the field trial plots cymoxanil + famoxadone (22.1 + 16.6%, EQUATION PRO WP*) and metalaxyl** + mancozeb (200 g/L + 1.600 g/L, RIDOMIL MZ 72WP) were the most effective. This facts were confirmed by statistic Duncan-test and data of yields.

The appearance of Phytophthora infestans epidemic was influenced by the climate conditions too during May and June when the minimum temperature was 12 oC, and the maximum 20 oC, the rain quantity more than 120 mm, the air humidity above 75%, these conditions promote the appearance and spread of fungus.

In modern nutrition, bioactive materials of different vegetables are especially important to be researched. The experiment was carried out on March 30, 2016 (sowing date). Mineral element content (B, Ca, Cu, Fe, K, Mg, Na, P, S, Zn) was evaluated on the 60th, 85th and the 105th day of the vegetation period. The data are presented as the mean of five varieties which can give the real state of these parameters of beetroot grown on lowland chernozem soil.

In the young beetroot leaves (60 days) the mineral element content was higher than in the older ones (85 days). The calcium and magnesium content of the leaves was much more favourable (10 times higher) than in the root. The potassium content of leaves has reached the amount of 5000 mg kg-1, but at the same time more than 3000 mg kg-1 was detected in the improved root. This value is favourable for the potassium supply of the human organism.

The sulphur content (1300 mg kg-1) of the leaves was the highest on the 85th day of vegetation period. Similar tendency was detected for boron content (2.45 mg kg-1), while for iron content it was higher (28.23 mg kg-1) in the younger leaves (60 days).

Finally, it can be concluded that the increased element content of beetroot leaves will be a favourable source of mineral element supply of the human organism.

Jordan suffers from drought and depletion of water resources. In-field crop management, the issue of irrigation scheduling is important and influential. In this research note, a simple method was developed for scheduling surface irrigation of field crops based on inputs of crop ecology, effective root depth, soil texture, soil hydrology, and logical mathematics. It was concluded that the science of mathematics has succeeded to meet academic irrigation scheduling in terms of surface irrigation for field crops based on both soil hydrological and physical traits. Extension scholar has a decision to choose mathematical irrigation model depends on the traditional inputs or updating the model by searching for renewable inputs such as different varieties root depths, optimum row spacing of each crop, drip irrigation mathematical modelling, and digital sensing. In both cases, the input related to the effective root depth is a major and basic factor in mathematical irrigation scheduling. It is, therefore, recommendable that extension research-based systems should focus on basic mathematics to capacitate the complementary role of academics, research, and extension in irrigation modelling, and rural development.
