Abstract
The purpose of the study was to explore the effectiveness of various modifications of the preparation Megamix and complex macrofertilizers in cultivation of the spring wheat variety Ulyanovskaya 100 in the forest-steppe of the Middle Volga region. The factors used in the experiment contribute to a yield increase by 0.37 - 3.12 c / ha. The use of the Megamix-Zinc modification with complex mineral fertilizers gives the greatest yield increase compared with the control group which amounts to 11%. All modifications of the Megamix preparation have a positive effect on the structure elements of the spring wheat yield. The highest test weight is observed in the Megamix-Zinc option with previous application of mineral fertilizers. The increase in this indicator from the factors used was 4.8 - 18.7 g / l, depending on the option. Under the influence of the studied factors, the vitreousness of the spring wheat grain increases by 1.28 5.83%. Top dressing has a positive effect on the weight of 1000 seeds. This indicator increased by 0.49 - 2.80 grams, compared with the control option.
Highlights
The studies focused on the development of adaptive technologies for cultivation of crops to get high yields, to increase plant resistance to adverse environmental factors, to decrease pesticide load and, to improve the mineral nutrition of plants with macro- and microelements are playing a significant role [1,2]
The mechanism of action of growth regulators presupposes activation of all metabolic processes in the plant, which in turn helps to increase the yield of agricultural crops by 15-30%, reduce the amount of mineral fertilizers used, optimize the mineral composition of plant biomass, and reduce crop losses
Special attention has recently been paid to the introduction of technologies for the use of physiological biochemically active substances in cultivating crops, including spring wheat
Summary
The studies focused on the development of adaptive technologies for cultivation of crops to get high yields, to increase plant resistance to adverse environmental factors, to decrease pesticide load and, to improve the mineral nutrition of plants with macro- and microelements are playing a significant role [1,2]. There are many methods and techniques that can be applied to increase yields without compromising product quality One of these methods is pre-sowing seed treatment, as well as foliar treatment of vegetating plants with preparations of growth-regulating and growthstimulating action [2,3,4,7,8,9]. Such preparations are an extensive group of natural and artificial organo-mineral substances that, in small doses, activate the metabolism of cultivated plants. More than five thousand preparations of growth-regulating and growth-stimulating action are known [311]
