Application of the preparations "Azofit N" and "Azofit P" with mineral fertilizers in the cultivation of spring wheat in the steppe zone of Altai Krai

Abstract

The article presents the results of a field experiment to study the effect of using agricultural biologicals “Azofit N” and “Azofit P” against the background of different rates of application of mineral fertilizers in field fertility zones and their aftereffect on the yield of spring wheat and economic efficiency. The experiment was laid down on the APC "Kolos" in the Romanovsky district of the steppe zone of Altai Krai in 2023 at three levels of fertilizer doses (85%, 70% and 50% of the control) in three field fertility zones (low, medium and high). The control one was the farm technology variant with the basic dose of mineral nutrition (100%) without the use of biopreparations. Field productivity zones were identified based on the “Cropio” digital platform. In 2024, the aftereffect of using the 2023’ experimental variants were studied by observing crops on the same basic sites, but without biopreparations and with the same dose of mineral nutrition. Based on the results of the experiments, the biological yield of spring wheat and the economic efficiency of the experimental variants were assessed over two years of observations.
