Economic Efficiency of Mineral Fertilizers Applied for Sorghum Growing in the Forest-Steppe Zones of the Southern Urals

Abstract

During the period 2016-2018, field experiments were conducted in the Scientific Training center of Bashkir State Agrarian university. The aim of the experiments was to study the effect of introducing calculated doses of mineral fertilizers on the expected sugar sorghum fresh-yield in the southern forest-steppe zone of the Republic of Bashkortostan. The purpose of the research work is to determine the amount of mineral fertilizers applied to get the expected sugar sorghum fresh yield. During the research work, it was revealed that doses of mineral fertilizers applied for sugar sorghum growing should be defined taking into account the expected fresh yield and yield removal rates. According to the result of the studies, the highest fresh yield of 65.0 t/ha was received from Seville sugar sorghum during the second sowing period (21-30 of May). N₈₅P₃₇K₃₉ rate of mineral fertilizers applied to get the expected harvest contributed to the yield increase by 166.4% in comparison with the control rate and yielded 40.6 t/ha.
