The results of the influence of pre-sowing seed treatment, the main application of mineral fertilizers and foliar fertilizing with ammonium nitrate, urea, organo-mineral fertilizer D2 or bacterial preparation Escort-bio on the formation of productivity and quality of spring wheat of the Elegia mironovskaya variety are presented. Experimental investigations were carried out on the Chernozem of the South during 2014-2016. In the conditions of the educational, scientific and practical center of the Nikolaev NAU. The results of research showed that the introduction of nitrogen-phosphorus fertilizers before sowing and foliar fertilizing of spring wheat crops on average over three years provided an increase in grain yield by 1.00–1.58 t/ha in variants with water treatment of seeds and by 1.08–1.72 t/ha when processing seeds with microbial preparation Escort-bio. Pre-sowing treatment of escort-bio seeds contributed to the additional production of 0.14–0.28 t /ha of grain, depending on the fertilizer option. The highest grain yield was formed by applying N30P30 for pre-sowing cultivation, treating seeds with a microbial preparation and carrying out the phase of plant exit into the tube of feeding with ammonium nitrate with a dose of N30. Pre-sowing treatment of escort-bio seeds and foliar fertilizing contributed to an increase in the payback of fertilizers by increasing the yield of spring wheat. The maximum specified indicator is determined by the background of bacterial seed treatment, the main application to the sowing of N30P30 and carrying out two top-UPS with organo-mineral fertilizer D2 or Escort-bio. Application of fertilizers and foliar top-UPS on average over three years increased the protein content of spring wheat by 0.7–1.4 %, and gluten – by 1.2–1.9 %. The maximum both indicators of grain quality are determined in the version of the main application of N30P30 with making-up at the beginning of the earing phase with urea at a dose of N30 –14.9 and 28.1 %. The conditional yield of protein and gluten from a hectare of spring wheat sowing with an improvement in the background of plant nutrition grew and reached maximum values in the variants of N60P30 before sowing or N30P30 before sowing with fertilizing with ammonium nitrate at a dose of N30 in the phase of exit to the tube |
