The purpose of this paper is to presents the main results on the study of the effect of different doses of vermicompost on the growth and yield of pepper in the conditions of Yakutia. Experiments on testing fertilizers were carried out on peppers of the “Nezhnost” variety. In variant, there were 10 plants. Experimental scheme: 1 variant - was only with soil; variant 2 in addition to this vermicompost - 100 g; variant 3 vermicompost - 300 g; variant 4 vermicompost - 500 g; variant 5 - the biological product “Baikal EM 1” - 100 ml per well with 100 g semi-rotted manure. The optimal rate of application of vermicompost was determined at which plant growth increased by 20.89%, the total leaf area - by 36.55%. All this together affected the yield of pepper. The second best result was obtained when using the biological product “Baikal EM 1”. At the same time, plant growth indicators improved by 12.18%, the total area of the leaf increased by 24.72%. The data obtained complement the scientific base in the field of northern crop production in terms of the use of vermicomposts from local raw materials.

The purpose of this paper is to the results of experiments to study the effect of vermifertilizers on the agrochemical properties of soils and the quality of pepper in Yakutia. Experiments on testing vermifertilizers were carried out on peppers of the “Nezhnost” variety. Experiment scheme: 1 variant - was only with soil; variant 2 in addition to this vermicompost - 100 g; variant 3 vermicompost - 300 g; variant 4 vermicompost - 500 g; variant 5 - the biological product “Baikal EM 1” - 100 ml per well with 100 g semirotted manure. Vitamin C and nitrate content was studied in fruits. During the experiments, it was found that the optimal doses of vermicomposts made it possible to increase the content in soil mixture of nitrogen by 0.11%, P by 16.37%, K by 8.02% and organic matter by 0.34%. At the same time, vitamin C increased in the fruits of pepper and the content of nitrates decreased. The best result was obtained by the variant where 500 g of vermicompost was used, the second-best result was for the biological products “Baikal EM-1”.

The question of applying the most progressive technologies of cleaning work of efficient systems of machines is of paramount importance. In solving tasks to ensure the sustainable development of agricultural production, reliable supply of the population of the country, food in food is an important place to strengthen the material and technical base of the agro-industrial complex, its targeted technical re-equipment. In this regard, the goal of the work is to study the rational method of increasing the performance of the screw screw conveyor, allowing you to create a small-sized structure, is an increase in its revolutions. The article provides research in the method of increasing the performance of the screw screw conveyor, allowing you to create a small-sized design by increasing its revolutions. The technology of the work of conveyors-grab trucks was described, the work mechanism was investigated and the disadvantages of work were described, namely, in defective providing the possibility of grain transfer over long distances along the spatial track or complicates the technological scheme. Such an organization of harvesting on the scale of the country involves the creation and implementation of several systems of high-performance cleaning and transport equipment primarily in the main grain areas.
