Abstract
According to the legislation of Ukraine, one of the requirements of organic crop production is the use of organic seeds and organic planting material. High productivity and quality of sowing material for organic production of agricultural products can only be obtained with the full supply of plants and soil to nutrients and the protection of plants from diseases, pests and weeds. The purpose of the work was to study the technologies of protection and nutrition of legumes (peas and soybean) with the use of domestic biopreparations in seminal organic agrophytocenoses. The research was carried out in the right-bank forest-steppe of Ukraine. The influence of technologies of the use of complexes of biological products of natural origin on the productivity of the seed material of peas and soybeans, its seed quality and phytosanitary condition of crops were studied. The study evaluated the potential of legume crops by main economic characteristics in the conditions of use of organic production technologies in different phases of ontogenesis of plants. Positive influence of technologies of complexes of biological preparations on growth and development of cultivated plants, which was reflected on their biometric indices, is established, finally forming the yield of peas and soybeans and high crop quality. In general, the use of all investigated technologies using biopreparations on peas and soybeans ensured obtaining quality organic seed material that meets the requirements of DSTU 2240-93 for reproductive seed.
Highlights
Because of the reorientation of the export market of Ukraine to the EU market in the country, the number of agricultural producers willing to produce organic products has steadily increased in recent years
It was established that these technologies had a definite influence on the growth and development of a cultivated plant, which was reflected in its biometric parameters, resulting in the increase of the yield of peas and seed quality
The research established the positive effect of technologies using all complexes of biological preparations on the yield of legumes as well as on the seed quality of the studied crops
Summary
Because of the reorientation of the export market of Ukraine to the EU market in the country, the number of agricultural producers willing to produce organic products has steadily increased in recent years. The demand for organic farming in the European Union is quite large and organic products have a stable price, which is an attractive factor for many agricultural enterprises in Ukraine. A special niche in organic production is occupied by legume crops. Flour, various confectionery, food and feed concentrates are produced from legume crops. Legumes play an important role in improving soil fertility. Due to this, they are one of the best precursors in crop rotation for cereals and industrial crops
