Agro-economic evaluation on producing seeds of Sudanese grass in the steppe zone of the Lower Volga region of Russia

Abstract

The creation of a lump base for the livestock industry in the Nizhnevolzhsky region requires expanding the range of feed that can provide a complete diet for farm animals. Introduction of annual fodder grasses into the field crop rotations of the region is recommended, of which one of them is Sudanese grass with undeniable nutritional value. However, the most cost-effective sowing method for obtaining high-quality seeds of Sudanese grass in the Lower Volga region of Russia is the pre-requisite. Therefore, this work was carried out in 2020 to 2022 In a two-factor experiment established in the dry steppe zone, where the influence of sowing methods on the yield of Sudanese grass seeds was studied. Two factors were studied: variety and method of sowing. The results of the experiment were made using dispersion analysis. The assessment of economic efficiency was determined using data on the cost of seeds according to the seed service of the Federal Scientific Center of Agroecology of the Russian Academy of Sciences for 2020-2022.It has been determined that the most effective way for producing seeds is wide-row with a width of 45 cm between the rows and a seeding rate of 1.2 million pieces. germinating seeds/ha. By sowing seeds in this way, an average yield of 1.81 t/ha was obtained. The profitability of seed production is 1.4 times higher than when sowing seeds of Sudanese grass in an ordinary way, with a row width of 15 cm, with a norm of 1.2 million pieces. seeds/ha the reliability of the results of the study was confirmed by analysis of variance, the studied factor as a result of the experiment is 73.7%.
