Formation of a crop of spring triticale depending on the background of nutrition and pre-seed treatment of seeds
Journal Title: Наукові горизонти. Scientific Horizons - Year 2018, Vol 70, Issue 7
Abstract
The article presents the results of researches carried out during 2014-2016 on the black earth in the south in the conditions of the educational-scientific-practical center of the Mykolayiv NAU, located in the south of the Ukrainian steppe, with the triticale Yarim. The main task of the research was to improve the nutrition of triticale plants of the spring variety of the Nightingale of Kharkiv on the basis of resource conservation - on the background of the main fertilizer N30Р30 used pre-sowing seed treatment and nutrition of plants in the main phases of vegetation by modern biopreparations. It was determined that only seeding before sowing can increase the yield of grain by an average of 7,6%, and this measure, together with the introduction of foliar feedings (in the phases of the plant's output into the tube and earing), ensures the formation of virtually the same level as the feeding of N30 ammonium nitrate during the period of plant release in the tube or N30 carbamide in the ear staining phase along the same background of the main fertilizer. It was established that the increase of grain productivity of the triticale of the spring for optimization of nutrition is due to the increase in the length of the ear, the number of grains in it, the mass of grain from the ear. It is determined that the payback of the unit dp mineral fertilizers increase the yield of grain for their joint use with biopreparations significantly increases. For the introduction of N30Р30 to sow 1 kg d.r. fertilizers received 11,3 kg of grain growth without seed processing and 12,3 kg of grain for this measure. Feeding to the phase of plant release in the N30 tube provided indicators at 15,0 and 16,4 kg of grain; twice the preparation D2 – 17,2 and 18,7, and Escort-bio 18,5 and 20,0 kg / kg, respectively. It is determined that due to biopreparations, the return on the moderate dose of fertilizer in the main application to the sowing increases from 2,7 to 7,7 kg of grain, depending on the preparation, the seed treatment and the number of feedings.
