INFLUENCE OF FERTILIZED FERTILIZERS BY BIOPREPARATIONS ON POTATO PRODUCTIVITY IN THE CONDITIONS OF THE RIGHT BANK

The paper presents the results of research on peculiarities growth, development and formation elements productivity medium-sized varieties potatoes Miracle, depending impact biological products in foliar feeding. use leads to a prolongation growing season medium-ripe potato variety Miracle years average by 3 - 13 days. shortest vegetation period 80 days is observed control variant (var. 1) longest 91 93 was experimental variants 7 8 where application germination phase flowering preparations Kristalon special Intermag Potatoes, respectively. Morphological characteristics increased under influence applied comparison with variants. At same time, largest habit plants formed experiment full budding Crystal Potato used (variants 8, respectively). levels yield marketability were high, while conditions 2019 more favorable compared 2018 an 5.3 7.5 t / ha. It should also be noted that lowest values tubers background N90P90K90 used, feeding phases led increase above indicators. highest options for level starch content research, contrary, reacted negatively products. And collection per unit area directly depends tubers, accordingly obtained obtained.
