Influence of fertilization with green manure and treatment on yield, economic and energy efficiency of spring barley

Abstract

The influence of the application of fertilizers with green manure and soil treatment on the yield, economic and energy efficiency of spring barley has been studied. The aim of the work was to identify the impact of the implemented tillage systems with elements of minimization and fertilization with elements of biologization on the productivity and economic performance of spring barley. It is established that in the conditions of the Right-Bank Forest-Steppe of Ukraine the aftereffect of application of high norms of organic and mineral fertilizers on typical chernozem has a positive effect on spring barley yield, increasing it, compared to control, by 0.55–1.10 t/ha per plowing, by 0, 65–1.35 t/ha for deep tillage and 0.55–1.30 t/ha for shallow tillage. It was found that the highest crop yield (3.85 t/ha) was obtained against after shallow tillage and aftereffects of fertilizer application with manure. The use of fertilizers helped to increase the protein content in the grain of spring barley. The influence of tillage systems on the protein content of barley was reliably noted only in the variant of fertilizers with straw & green manure. The use of shallow tillage with organic manure and fertilizer provides a decrease of 142.9 UAH/t of the cost of production, an increase of 886 UAH/ha of net profit and a 21.2% reduction in energy consumption compared to plowing.
