Barley Productivity and Protein Content: Fertilization Effect

Abstract

The results of study of yield and protein content in grains of chaffy and naked barley in the experiment with the increasing rates of mineral fertilizers were described. The relationship between the nitrogen content in the leaves of barley plants and protein content in grains were calculated. For the Acha variety the optimal fertilizer rate was based on the yield of 3.0 t/ha. Higher fertilizer rates were needed to realize yield potential of the Philadelphia and Nudum 95 varieties based on the yield of 5.0 t/ha. The highest protein content in the barley grain was formed in the options with the calculated rate of fertilizers for the yield of 5 t/ha: Acha-15%; Philadelphia-13.5%; Nudum 95-18%. A positive relationship was established between the nitrogen content in the leaves and the amount of protein in the grain: r = 0.934; 0.880; 0.877 for the Acha, Philadelphia, Nudum 95 varieties, respectively. In collecting protein from the area unit, the Acha variety has shown the best results, the advantage of which was 131 kg/ha compared to the Philadelphia variety, and 95-127 kg/ha compared to Nudum 95.

The yield and grain quality of barley varieties in the northern forest steppe of the Tyumen region

“…The problem of creating highly productive barley varieties for the intended use and the development of effective technologies for their cultivation was described in several works by the scientists (5,(9)(10)(11)(12)(13). As a promising technique, presowing treatment of wheat and barley seeds with fungicides together with growth regulators and stimulants was considered.…”
