Influence of the main agrotechnical techniques of cultivation on the yield of plague seeds (Setaria Italica (L.) P. Beauv) in the Lower Volga Region

For the arid conditions of Lower Volga region, plague is a promising forage crop. The article presents results assessing study effect seeding rate and sowing methods on yield seeds variety Stachumi 3, which made it possible to identify optimal option for obtaining maximum yield. was carried out experimental field Federal State Budgetary Scientific Institution Russian Research Institute Sorghum Corn Rossorgo, located in suburban microzone Saratov region geographically southern part chernozem zone region. climate sharply continental dry. soil chernozem. obtained were confirmed by analysis variance two-factor experiment six gradations factor A (seeding from 1.25 7.50 million pcs./ha) three B method with row spacing 70, 30 15 cm), according data revealed significant differences influence seeds.
