Abstract

Fertilizers are a means of influencing both the value of the yield and its quality. The quality of the yield will vary depending on the types of fertilizer, the timing and methods of their application, and the balance of ratios for the main nutrition elements. Under the conditions of field experiments on sod-podzolic soil, the influence of various types of top-dressing on the yield and quality traits of barley grains of the cv. Novichok, Rodnik Prikamya and Pamyati Rodinoj was studied. High efficiency of application of all top-dressings on grain yield capacity of barley cv. Novichok has been established. The use of liquid mineral fertilizer KAS in the tillering stage contributed to an increase in the yield of barley cv. Rodnik Prikamya and Pamyati Rodinoj by 0.34 and 0.31 t/ha. The barley cv. Pamyati Rodinoj also responded positively to the input of the preparation Alfastim in the heading stage; the grain yield increase was 0.82 t/ha. The high efficiency of top-dressings on the physical properties of grains has been established in barley cv. Novichok and Pamyati Rodinoj. The protein content in the cv. Pamyati Rodinoj was increased during treatment of sowings with prepara-tion Amino Start in the tillering stage by 15.0–16.5 g/kg. In the cv. Novichok, when inputting the growth stimulant Alfastim at heading stage, an increase in protein content by 4.0–4.8 g/kg was noted. In terms of fiber content, the obtained grains of all cultivars meet the requirements of the first class grain.

Summary

Introduction

Barley is a unique culture, both in biological features and in economic-and-useful features. Its main advantages are drought resistance, high productivity, good feed quality and the possibility of universal use. In the Kirov region, the main sowing areas of barley are used to produce grain fodder and in mixed feed industry, since the grain of this crop is distinguished by a better balance of protein, including the main essential amino acids. An urgent solution to the problem of increasing grain productivity and quality could be the expansion of sown areas for new high-yielding domestic barley cultivars and the development of technologies for their cultivation for fodder purposes. In terms of yield capacity and grain quality, they are not inferior to cultivars of foreign breeding, but in unfavorable conditions exceed them [1, 2]
