Ryabokіn T. Features yield formation of different varieties of pea morphotypes depending on the intensification of cultivation technology in the northern part of the Right-Bank Forest-steppe

The object of investigation is formation process of high yielding rate of pea and grain quality on the grey forest soils. The aim of researches is theoretical substantiation and developing of optimal parameters of yield formation of pea varieties of different morphological types depending on intensification level of growing technology in condition of northern part of Right-bank Forest-steppe of Ukraine. The methods of inquiry were comparative-weighting, quantitative, chemical, mathematical-statistical, calculated-comparative. At first scientifically based and improved growing technology elements of the pea varieties of different morphological types, which ensured yield on the level 3,09-3,59 t/ha, in favourable years at the level 4,54-5,41 t/ha and improving of it quality, and has influence on raising of grain production, accumulation of substantialamount of symbiotic nitrogen and bettering of soil fertility. The most scientific results were implemented in agriculture enterprises of Kirovograd and Vinnytsia regions where on total area 438 ha were provided yield incrementation of pea 0,74-1,08 t/ha comparatively to the existing growing technologies. The area of application is agricultural production.
