Analysis of the effect of the products «Agromaximum 5» and «Agroverm master» on the economically valuable traits of winter wheat cultivated in the Penza region

Abstract

The current paper deals with the results of analyzing the effect of optimal application rates of the biological products «Agromaximum 5» and «AgroVerm Master» and their impact on winter resistance, productivity, and grain quality. The biological products «Agromaximum 5» and «AgroVerm Master» are complex fertilizers containing nitrogen-fixing bacteria, phosphate-mobilizing bacteria, potassium-mobilizing bacteria, humic acids, and amino acids. They are used for plant nutrition, both for pre-sowing seed treatment and foliar application, which improves nutrition and productivity, and protects against diseases. The purpose of the current study was to study the efficiency of the biological products «Agromaximum 5» and «AgroVerm Master» at specified doses to improve winter resistance, productivity, and grain quality. In the control variant, seeds were treated with the fungicide Kinto Duo at a dose of 2.5 l/t. In the second variant, the biological product «Agromaximum 5» (1.25 l/t) was added to Kinto Duo (2.5 l/t). In the third variant, in addition to Kinto Duo and «Agromaximum 5» the seeds were treated with the biological product «AgroVerm Master» at a dose of 1.5 l/ha during late tillering to early booting stage. The obtained data have shown that pre-sowing treatment of seeds with 1.25 l/t of the biological product «Agromaximum 5» significantly increased the aboveground biomass (by an average of 15.7%), a tillering coefficient (by an average of 27.8%), a depth of the tillering node (by an average of 21.8%), a number of nodal roots (by an average of 22.2%) and winter resistance (by an average of 6.7%). The treatment of crops with the biofertilizer «AgroVerm Master» during late tillering to early booting stage has improved productivity of the winter wheat variety Fotiniya by 0.66 t/ha (or 10.3%) and all indicators of individual grain productivity.
