Role of microbiological fertilizer and siderates in increase productivity and quality of potato

Results of researches on management of potatoes productivity by means of siderat, the mineral and bacterial fertilizers received in three short-term experiences from 2010 for 2017 are presented. Purpose of researches: to increase productivity and quality of potatoes at simultaneous decrease in anthropogenous loading on agrocenosis due to complex use of binary siderat, the lowered doses of mineral fertilizers in a combination microbiological medicines. In stationary field experiment (2010-2012) the maximum potatoes productivity (32,2-35,5 t/ha) was received from using mineral fertilizers N_45-90P_60-120K_60-120 in a crop rotation link [(radish olive + vika) - potatoes], at the same time efficiency of prelanding processing of tubers bacterial medicines was 9,2-15,0%. In experiences on the sod-podsolic soil an increase of potatoes productivity (variety Udacha) from microbiological medicine (Agrinos) in 2015 made 12,4%, at simultaneous increase in starch and vitamin C in production; in rather damp 2016 and 2017 an increase of efficiency of middle-early variety Gala reached 8,5 t/ha or 24,5% to the level of mineral background (N₉₀P₉₀K₉₀). In option with the dose of NPK lowered by 30% and Agrinos application [N₆₀P₆₀K₆₀ + Agrinos A + B (5 + 2,5 l/ha)]: level of productivity was on 5,8 t/ha (16,7%) above full dose of NPK, along with it are noted: high content of starch and vitamin C, excellent culinary qualities, low level of nitrates; the conditional income for 69,5 thousand rub/ha above NPK background, low prime cost (4,33 rub/kg), high payback (5,55) and profitability of production of 131%.
