06.01.01 General agriculture, crop production (agricultural sciences)
Description
The article presents data from 3-year observations of the weather conditions influence on the effectiveness of applied fertilizers in the crops of the Yantar variety of coriander on leached black soil (chernozem) under the conditions of land use at the training and experimental station of the Stavropol State Agrarian University. The materials presented in the article indicate that the agrometeorological conditions of 2016 and 2017 as a whole were most favorable for the formation of a coriander crop. As studies have shown, the amount of precipitation during the spring-summer period of the growing season of the crop was 337 mm, which is 11% higher than the long-term average. The year 2018 in terms of climatic indicators turned out to be significantly worse than the previous two years, the amount of precipitation during the coriander vegetation period turned out to be 125 mm or 58% lower than the long-term average, which significantly affected the crop yield this year. In the most optimal agroclimatic indicators in 2016, the maximum increase in crop productivity was noted on the N60P60K60 variant - 0.49 t / ha, on the same option in moistened 2017, the increase level was 0.39 t / ha. Last year2018 was marked as extremely arid, the maximum increase in coriander yield was noted on the option with P60 and amounted to 0.35 t / ha. It was established that the maximum increase in the yield of coriander oil seeds on average in the experiment on leached chernozem was achieved with the options: P60 is 0.37 t / ha, N60P60 is 0.41 t / ha, N60P60K60 is 0.34 t / ha, which significantly higher than other fertilized experience options. The economic efficiency of the coriander seeds production, depending on the types and combinations of minerals, turned out to be most effective when applying a single mineral fertilizer, P60, compared with other options for experience, an increase in profit to 17500 rubles and the level of profitability of production by 23%

Description
Remineralization of leached chernozem was carried out by applying such rocks as loess-like loam, shell limestone, apatite phosphogypsum. We have revealed that the introduction of species didn’t change substantially the content of boron during the growing season. We have also displayed the seasonal dynamics of macro variants of the experiment and the increase in the content of food items in the phase of active growth of winter wheat. Seasonal dynamics of trace elements is expressed, but can not be expressed with certain regularity
