Agromeliorative methods of cultivation of a new variety of soybeans Volgogradka 2 under irrigation conditions

Abstract

Abstract The Volgogradka 2 variety is highly responsive to irrigation water, especially under differentiated irrigation regimes with an average of 3.18-3.23 t/ha compared to the control (2.87 t/ha). In favorable years, it provides grain harvesting up to 3.52 t/ha, in dry years – less (up to 3.28 t/ha). The average crude protein content is high - 39.5…41.6%, especially in 2014 - 40.6…43.9%. The process of fat accumulation is less subject to variability over the years – 14.6…19.5%. Complex-valuable indicators, such as the gross collection of protein, fat and their total output significantly increases in the options of fractional irrigation mode compared to the control – by 5.8-7.3%. Over the years of research, the productivity potential of the new soybean variety Volgogradka 2 has been significantly realized, which contributes to improving water management, increasing productivity, grain quality, and spreading the area under cultivation. Thus, a fundamentally new soybean variety with a complete type of stem growth during the period of mass flowering, a low lodging-resistant stem and high attachment of lower beans, a short growing season was developed using traditional breeding methods, which contributes to a significant increase in the yield and quality of grain in terms of protein content relative to standard varieties VNIIOZ 76 and VNIIOZ 86. The introduction of the new variety will expand soybean crops in the Lower Volga region and increase the production of domestic soybeans.
