The influence of mineral fertilizers and soil treatment methods on the yield of oats

Abstract

The article summarizes the results of studies (2013 and 2018) conducted on leached heavy loam Chernozem in the Republic of Mordovia. The object of study is oats (Horizon variety). In the experiment, against the background of plowing, tillage and disking, the effect of mineral fertilizers was studied, which were represented by a complete mineral fertilizer (N32P32K32 –background), and fertilizing with mineral nitrogen in doses of 30 and 60 kg of active gradient/ha against this background. Analysis of oat yield shows that the collection of grain plowing in options without the use of mineral fertilizers (2.34 t/ha) had an advantage over the tillage and disking (2.15 and 2.04 t/ha), and in general, the experience increased the yield of oats by 0.43 and 0.53 t/ha. The maximum yield increases from the use of mineral fertilizers were obtained from the background of plowing, their value ranged from 0.49 to 1.03 t/ha compared with the option without fertilizers, there were less increases on the background of non-dump treatment of 0.21–0.57 t/ha and disking of 0.22–0.62 t/ha. Fertilizing with mineral nitrogen at a dose of 30 kg of active gradient/ha regardless of the methods of tillage showed an almost equivalent increase in the yield of oats by 0.20–0.24 t/ha compared with the background options (2.83, 2.36 and 2.26 t/ha, respectively, plowing, dump-free processing and disking). The most effective (an increase of 0.54 t/ha) was fertilizing with nitrogen at a dose of 60 kg of active gradient/ha against the background of applying a full mineral fertilizer using plowing.
