Assessment of the influence of agrometeorological conditions on the productivity of oats under conditions of application of various doses of sewage sludge

Abstract

The article considers the effect of increasing doses of sewage sludge (OSV) on the productivity of oats in various agrometeorological conditions, as well as the effect of different doses of OSV on some agrophysical properties of the soil and humus content. In the course of the study, it was proved that with an increase in the dose of OSV, there is an increase in the lowest moisture capacity, which characterizes the water-holding capacity of the soil. With the introduction of OSV in the soil, the humus content increases (with an increase in the sediment dose to 10 t /ha of dry matter, an increase in the percentage of humus is observed by 0.1%, with the introduction of sediment at doses of 25 and 30 t /ha, the humus content in the soil increases to 1.3%). The analysis of the data allows us to conclude that the agrometeorological conditions of the year have a significant impact on the yield of oats when using different doses of OSV. Thus, in wet years, the grain increase is from 6.0 to 11.5 c/ha (20 and 25 t/ha of WT), and in normal years – from 9.5 to 20.5 c/ha (25 t/ha of WT) compared with the yield of oat grain in dry years.
