Kostyna T. Optimization of growing technology elements of different varieties of pea morphotypes in conditions of the northern part Forest - Steppe

Оbject of research - the processes of growth, development, formation and photosynthetic grain productivity of varieties of peas of different morphotypes depending on the doses of mineral fertilizers, bacterial preparations and minerals. The aim is to reveal the peculiarities of growth, development and productivity element forming varieties of peas Lastochka and bezlistovogo morphotypes depending on the level of fertilizer, pre-sowing seed treatment with biologically active drug and micronutrient fertilizers. Methods field, measuring weight, quantity, chemical, mathematical and statistical, computational and comparative. For the first time in the Northern Forest-steppe conditions on gray forest soils scientifically technology of cultivation of varieties of peas of different morphotypes, which is based on the improvement of the system of fertilizers by making major elements of mineral nutrition and pre-treatment of seeds of trace elements in complex with nkulumane seeds drug based on the strain of nodule bacteria of the genus Rhizobium leguminosarum №200. Advanced technological elements of growing peas ensure receipt 2.85-3.18 t/ha ordinary varieties and leafless 2.82-3.38 t/ha. The main scientific results tested under production conditions during 2008-2009 on the area of 15 hectares, in 2010-2011 in the area of 25 hectares in the agricultural company "Agrofirma them. Shevchenko" Bakhmach district, Chernihiv region. Industry use - agricultural production.
