Abstract

The paper presents the results of 50 accessions of soybean research hay use of the base collection of the National Center of Plant Genetic Resources of Ukraine. The protein content in the green mass at various harvesting time: the beginning of flowering, formation beans and bean filling was studied. It is highlighted that the soy green mass is the richest in protein content in dry matter in the phase of the flowering beginning – 26.2%. In the next phase of development the protein content is gradually decreased. In the phase of filling of beans, it did not exceed 16% of dry matter. The greatest impact of weather conditions on the protein content in the green mass of soybean was observed in the beginning of flowering stage, and declined in subsequent development phases. Two stocks of high protein content in the green mass of soybean independed of the phase of plant development are identified.
