ЭФФЕКТИВНОСТЬ ПРИМЕНЕНИЯ МИКРОУДОБРИТЕЛЬНОЙ СМЕСИ МЕГАМИКС НА ПОСЕВАХ ЯРОВОЙ ПШЕНИЦЫ ПРИ РАЗНОЙ НОРМЕ ВЫСЕВА

Abstract

The aim of the work is to improve the methods of cultivation of spring wheat when using the micro-fertilizing mixture Megamix in the pre-sowing preparation of seeds, processing on vegetation of crops with different seeding rates in the forest-steppe of the Middle Volga region. The effectiveness of the use of stimulating drugs "Megamix" in the seed treatment system and the use of drugs for vegetation is considered. The paper presents the results of studies of the effect of drugs on the development of spring wheat plants at different seeding rates (4.0; 4.5; 5.0 million vsx. sem/ha). The analysis of the effectiveness of the use of Megamix preparations and their effect on the dynamics of dry matter accumulation, indicators of photosynthetic potential and net productivity of photosynthesis, as well as on the yield of spring wheat, is done. It has been established that the use of stimulating drugs Megamix during seed treatment and during the growing season have a positive effect on the photosynthetic potential of crops. This indicator increases with the use of Megamix drugs. It reaches its maximum performance when processing seeds with Megamix Seeds 2 l/t, when processing spring wheat plants with Megamix Pro 0.5 l/ha (in the tillering phase) + Megamix Nitrogen 0.5 l/ha (in the flag leaf phase). A significant increase in the yield of spring wheat was found when using the drug Megamix Seeds 2 l/ t (seed treatment) – 4.08 t / ha. It is established that in the conditions of the forest-steppe of the Middle Volga region, the increase in the yield of spring wheat on average for all variants occurs with an increase in the seeding rate to 4.5 million crops/ha. With a further increase in the seeding rate to 5.0 million vsx. sem. / ha, the increase in yield is suspended.
