AGROECONOMIC EFFICIENCY OF USING MICRO-AND ORGANOMINERAL FERTILIZERS IN THE CULTIVATION OF BUCKWHEAT
2023
Glazova, Z. I.
The results of studies (2019-2021) to determine the effectiveness of the influence of the timing and methods of applying various micro- and organomineral fertilizers on buckwheat yields are presented. It has been established that the use of tested fertilizers: Biocomposite Correct (3.0 l/ha) - application to the soil; Biostim Start (0.7 l/t) - pre-sowing seed treatment; Grain Biostim (2.0 l/ha) + Biostim Bor (1.0 l/ha) - foliar top dressing during the period of branching-budding; Biostim grain (2.0 l/ha) + Biostim Rost (2.0 l/ha) - during the period of fruit formation provides the largest increase in grain yield by 0.11-0.42 t/ha, or 10.1-29.5%, as well as receiving a conditionally net income of up to 8290 rubles/ha. It was revealed that the application of fertilizers during certain periods of the growing season of buckwheat is agroeconomically justified, the additional grain harvest ranged from 0.12 to 0.19 t/ha and income from 4.73 to 5.89 thousand rubles per hectare. A detailed analysis of the yield of buckwheat showed that the effectiveness of fertilizers is in close dependence (r = 0.93 ± 0.12) on the conditions of crop development, determined by weather conditions. In the event of an unfavorable 2019, the share of the influence of fertilizers varied from 2.7 to 6.4%, and in 2021 this figure increases to 15.4-20.5%. Therefore, in order to optimize the mineral nutrition of buckwheat during the growing season, it is advisable to use corrective fertilizers produced by «Shchelkovo-Agrokhim» JSC, which may contain several microelements, as well as macro- and mesoelements, and therefore quickly eliminate nutrient deficiencies during critical periods of development
