ASSESSMENT OF THE EFFECT OF SPECIAL FERTILIZERS OF AO «SHCHELKOVO AGROKHIM» WITH DIFFERENT METHODS OF THEIR APPLICATION ON THE YIELD OF BUCKWHEAT
2021
Z.I., Glazova
The article presents the results of two-year research on the use of special agrochemicals of AO «Shchelkovo Agrokhim» for pre-sowing treatment of seeds, introduction into the soil and foliar dressing on crops of buckwheat variety Dasha. It was revealed that to obtain an additional yield of buckwheat grain at the level of 0.11-0.42 t/ha, it is more efficient to use the combined use of tested fertilizers, i.e. pre-sowing seed treatment (Biostim Start - 0.7 l/ha) + application to the soil before sowing (Biocomposite Correct -3.0 l/ha) + foliar dressing during the branching-budding period (Biostim for grain ‒ 2.0 l/ha + Biostim Bor 1.0 l/ha) and foliar feeding during the period of fruit formation (Biostim for grain ‒ 2.0 l/ha + Biostim Growth ‒ 2.0 l/ha). This interaction is very significant for increasing yields and varies from 10.1 to 17.6% depending on the conditions of the year. The share in the formation of the crop of the separate application of fertilizers is less significant and amounts to 3.0-7.0%. It should be noted the high degree of dependence of the effect of fertilizers on external conditions, determined by the input and temperature regime in each growing season: in 2019, their share in the formation of an increase in the buckwheat grain yield ranged from 2.2 to 12.0%, and in 2020 - from 5.4 to 18.3%, which is 1.52-2.45 times more. In order to increase the yield of buckwheat, along with organic-mineral complex fertilizers produced both abroad (2) and in Russia (3), it is advisable to use agrochemicals of AO "Shchelkovo Agrokhim" with different methods of their application.
