The influence of farming system elements on the yield of barley in the forest-steppe zone of the Trans-Urals

Abstract

The results of long-term stationary studies on the influence of farming system elements on the yield of spring barley in the forest-steppe zone of the Trans-Urals are presented. In the experiment, the role of the precursor; the main tillage (plowing and surface scarification); three levels of mineral nutrition were studied. The variation of the barley harvest for 2004-2014 under the influence of weather conditions that have direct and indirect impact on the formation of the yield of cereals is shown. The yield of barley primarily depends on the level of mineral nutrition. The average yield of barley sown after peas was 3.52 t/ha, with a variation in the range of 2.40-4.24 t/ha. In the variant where the precursor was oat, the yield of barley was 3.39 t/ha with a variation from 2.11 to 4.72 t/ha. The share of the contribution of the growing season weather conditions is 49% (the precursor is peas) and 72% (the precursor is oat). The minimum yield over the years of research was 1.44 t/ha on the variant where the precursor was oat, fertilizers were not applied, and the main tillage was surface scarification. The maximum yield was 5.57 t/ha on the variant with a dose of fertilizers N54P52K52 kg/ha, which were introduced by plowing.

“…Short summers and harsh winters require farmers to make quick decisions on growing crops and developing a farming system for them. The achievements of modern breeding, agrochemistry, and agriculture have ensured the advancement of agriculture to the north, where 100 years ago no one thought of cultivating grain crops, developing animal husbandry and poultry farming [6,7,8,9]. In digitalization era, it became possible to develop optimization models on a mathematical basis, which made it possible to increase the productivity of arable land with expanded fertility reproduction [10].…”
