Sowing qualities and yield properties of Sudanese grass depending on fractionation

Abstract

Research have been conducted on the development of recommendations for the obtaining and preparation of seeds of Sudanese grass for sowing, because in modern conditions increased demands are made on the quality of the sowing material. In the problem of realizing the genetic potential of a variety, an important role is given to the quality of the seed material. Therefore, all agrotechnical measures should be aimed at preserving and increasing the viability of seeds during their origin, growth, development and storage, that is, a special technology for growing seed should be developed and applied. Only with high seed quality the potential of the variety can be realized. The dependence of the yield of green mass of Sudan grass on the fraction of seeds and the seeding rate was revealed. In years with different weather conditions, seeds with the highest specific gravity had the best germination ability. On these options, the highest yield of fodder mass of Sudanese grass was noted. It was found that using the CAD separator, it is possible to select biologically valuable seeds of Sudanese grass, formed in the middle part of the panicle, remove lightweight impurity, improve the quality of seed and significantly increase the yield of green mass by 13%.
