  The aim of our study is to examine the effects of different groundcover methods on nutrient availability and uptake of apple orchard. The
  experiment was carried out at the orchard of TEDEJ Rt. at Hajdúnánás-Tedej, in Eastern Hungary. The orchard was set up on lowland chernozem soil in the Nyírség region. It was established in the autumn of 1999, using Idared cultivar grafted on MM106 rootstocks at a spacing of 3.8 x 1.1 m.
  The applied treatments were divided into two groups according to origins and effects. On the one hand, different livestock manures (cow,
  horse and pig), on the other hand different mulch-matters (straw, pine bark mulch, black foil) were used. The different manures and mulches
  were applied on the surface to test the effectiveness of these materials.
  The effectiveness of manure treatments was higher than the other treatments on AL soluble P content of soil. Mostly the manure treatments
  increased the AL soluble K of soil. Our all treatments increased 0.01 M CaCl₂ soluble NO3 ^- -N content of the examined soil layers. The effect
  of manure treatments was the highest. From the results it was evident that the amount of easily soluble organic nitrogen fraction distributed
  more homogeneously than the other mineral N fractions examined.
  Our results can be summarized as follows:
  1. Our results pointed out that the used ground covering matters divided into several categories regarding its effect.
  2. The available N, P and K contents of soil were mostly increased by applying manures.
  3. The effectiveness of straw, mulch and mostly black foil was lower.
  4. Differences were found between nutrient supplying treatments and the treatments which did not supply nutrients.

  Beetroot, also known as Beta vulgaris ssp. esculenta var. rubra, is a root vegetable that contains a substantial quantity of bioactive elements, notably antioxidants and anti-inflammatory properties. These bioactive compounds, including betalains, phenolics, and flavonoids, contribute to the health-promoting properties of beetroot. The antioxidant and anti-inflammatory effects of beetroot have been extensively studied in preclinical and clinical settings. The active compounds in beetroot have been reported to provide benefits in reducing the risk of various diseases, our research provides a comprehensive analysis of the bioactive compounds the inner and outer skin parts of the root structure. The findings aim to contribute to a deeper understanding of the potential health benefits associated with specific beetroot root components. Furthermore, the results have implications for optimising beetroot cultivation and processing for enhanced nutritional value. This research not only advances our knowledge of the phytochemical profile of beetroot outer skin but also offers valuable insights into the broader field of plant biochemistry and its applications in promoting human health and nutrition.

  In sustainable (wheat) production plant nutrition supply and fertilization play decisive roles among the agrotechnical elements, because of their direct and indirect effects on other agronomical factors.
  In long-term experiments, we studied the roles of agroecological, genetic-biological and agrotechnical factors in the nutrient supply, fertilization and its efficiency in wheat production under continental climatic conditions (eastern part of Hungary, Trans-Tisza) on chernozem soil. Our results have proved that there are different (positive and negative) interactions among ecological, biological, and agrotechnical elements of wheat production. These interaction effects could modify the nutrient demand, fertilizer (mainly nitrogen) response of wheat varieties and efficiency of fertilization in wheat production.
  The optimum N-doses (+PK) of wheat varieties varied from 60 kg ha-1 (+PK) to 120 kg ha-1 (+PK) depending on cropyears, agrotechnical elements and genotypes. The winter wheat varieties could be classified into 4 groups according to their fertilizer demand, natural and fertilizer utilization, fertilizer response and yield capacity.
  Appropriate fertilization (mainly N) of wheat could affect both the quantity and quality of the yield. By using optimum N (+PK) fertilizer doses, we could manifest genetically- coded baking quality traits of winter wheat varieties and reduce quality fluctuation caused by ecological and other management factors. The efficiency of fertilization on different baking quality parameters (wet-gluten, valorigraph index etc) were variety specific (the changes depended on genotypes).
  Our long-term experiments proved that appropriate fertilization provides optimum yield, good yield stability and excellent yield quality in sustainable wheat production. We could this get better agronomic and economic fertilization efficiency with less harmful environmental effects.

  With the increasing attention to the health promoting activities of the bioactive compounds from some plants, many researchers are focusing on the biological potential and mechanisms of certain cultivated plant species. In this review, we survey the olive and almond based extracts specific phytoconstituents and their associated health promoting effects that have been evaluated in experimental and clinical studies.

  Different 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.
