Effect of complex growth regulators depending on the fertilization background on the formation of winter wheat productivity
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 103, Issue
Abstract
The article presents the results of three years of studying the effect of the interaction of three levels of soil fertilization and the application of semi-synthetic broad-spectrum complex growth regulators on the growth, development and crop formation of winter wheat variety Spivanka. It was found that an increase in fertilizer rates from Р30К20+N30 to N60Р90К60+N60 caused a 9.8–13.1% increase in yield. The highest level of grain harvest of winter wheat was provided against the fertilization background of N60Р90К60+N60 with the simultaneous treatment of crops with test preparations in the fall. The highest yield of grain was obtained as a result of the joint use of Antistress, Mars-EL and a complex of essential amino acid preparations – by 10.6% more than in the control variant.
