The effectiveness of the use of micronutrient fertilizers and growth stimulants on the annual white melilot in the forest-steppe of the Samara Trans-Volga region
In 2016-2018 in the Volga NIISS, a study was made of the influence of physiologically active preparations on the feed productivity of varieties of annual white clover varieties of early maturity. The results of field experiments showed that the use of micro and biofertilizers, growth regulators makes it possible to fully realize the potential of white clover varieties, increasing productivity and increasing the collection of nutrients per unit area. On average, over the years of study, the most effective were the options with treatment with the growth regulator Mival-Agro and humic fertilizer Gumostim, the yield increase was 12.6-21.3 % in the early ripening variety Srednevolzhsky and 12.3-18.0 % in the mid-ripening variety Povolzhsky.
