Gryschenko O. Agrochemical estimation of long-term fertilization and rizogumin application to pea in right-bank Forest-steppe zone of Ukraine

Object - agrochemical processes in meadow chernozemic loam soil and processes of high yielded cultivars Madonna and Intensyvnyj 92 productivity formation under fertilization and rizogumin application. Purpose - the development and theoretical reasoning of fertilization system of pea cultivars Madonna and Intensyvnyj 92 and ways of biological nitrogen fixation increasing for fertility indexes of meadow chernozemic loam soil improving and stable yield harvesting. Methods - field experiment, laboratory, statistical methods, economic and bioenergetics estimation. Novelty - devised and theoretical reasoned technological procedure of mineral fertilizers and complex microbiological preparation rizogumin application to high yielded pea cultivars (Madonna and Intensyvnyj 92), which supply stable yield (4-6 t/ha), high production quality and optimization of agrochemical and biological indexes of meadow chernozemic loam soil. Results of researches - are employed in the practice of crop production and research activities. Branch - agricultural sciences.
