Influence of fertiliser systems with elements of biologisation and cultivation on the yield, economic and energy efficiency of spring barley

Abstract

The influence of the use of fertiliser systems with elements of biologisation and tillage on the yield, economic and energy efficiency of spring barley is investigated. The purpose of the study is to identify the impact of the implemented tillage systems with elements of minimisation and fertiliser with elements of biologisation on the productivity and economic indicators of spring barley. It is established that in the conditions of the Right-Bank Forest-Steppe of Ukraine, the aftereffect of applying high rates of organic and mineral fertilisers on typical chernozem has a positive effect on the yield of spring barley, increasing it, in comparison with the control, by 0.55-1.10 t/ha for ploughing, by 0.65-1.35 t/ha for deep chisel cultivation and by 0.55-1.30 t/ha for shallow. It was identified that the highest yield of the crop (3.85 t/ha) was obtained against the background of shallow flat tillage and the aftereffect of organo-mineral fertiliser using manure. The use of fertilisers contributed to an increase in the protein content of spring barley grain. The influence of tillage systems on the content of barley protein was reliably observed only in the fertiliser variant with the introduction of straw, green manure, and mineral fertilisers. The use of shallow chisel tillage against the background of organo-mineral fertiliser provides a reduction in the prime cost of production by UAH 142.9/tonne, an increase in conditional net profit by UAH 886/ha, and a 21.2% reduction in energy costs compared to ploughing
