Ogurtsov Y. Productivity forming of new pea varieties depending on the technological practices of growing in the eastern part of the Forest-Steppe of Ukraine conditions

Subject: processes of growth, development and productivity formation in the new pea varieties depending on the influence of the investigated cultivation technology elements. Aim: development of basic methods of agrotechnics for the new pea varieties of a leafless morphotype in the conditions of the eastern part of the Forest-Steppe of Ukraine. Methods: laboratory, field, mathematic-statistical, economic. Novelty: to determine norms of receipts and coefficients of the use of basic elements of mineral nutrition, optimum method of soil basic treatment, sowing rates, care of crops method, date and method of harvesting for the new leafless varieties of pea. Results: grain yield increase with this technology was 5,31 and 5,19 t/ha, net income - 4919 and 4796 uah/ha and profitability level - 248 and 246%. The coefficient of power efficiency - 2,60-2,64. Application stage: the results of researches are inculcated in SESF PPI nd. a V.YA. Yurjev of "Elitnoye", "Red Wave" and "Red October" on the total area of 119,6 ha, that provided the increase of net income by 234-452 uah/ha and profitability level by 18,2-47,6%. Application area: agricultural enterprises of all ownership forms.
