The effect of vermicompost on the agrochemical properties of soils and the quality of pepper in the conditions of Yakutia

Abstract

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”.
