Biohumus “Sis” for the ecologically pure agricultural production

Abstract

This study aimed to investigate the influence of the microbial biohumus obtained from organic non-toxic wastes on the yield of three varieties of peppers, identification of the effect of biohumus on soil physicochemical parameters, to determine the ecological significance and economic feasibility of biohumus application. The photosynthetic activity of plants and accumulation of ascorbic acid in the tissues of peppers were investigated. The experiments in the vegetation cabin condition have been carried out according to the following variants: 1. Control, 2. Biohumus, 3. N60P60K60, 4. Biohumus + N60P60K60. The yield of a variety of Jermatnayin hska pepper in the vegetation cabin conditions in the Biohumus (237 c/ ha) variant was lower than in the “Biohumus + N60P60K60” variant and was higher from “N60P60K60” and “Control” variants (277c/ha, 229 c/ha, and 191c/ha respectively). The yield of a variety of Arajnek pepper in the Biohumus (286 c/ha) variant was lower than in the “Biohumus + N60P60K60” variant and was higher “N60P60K60” and “Control” variants (320c/ha, 265c/ha, and 228c/ha respectively). The yield of a variety of Loshtak pepper in the “Biohumus” (335.7 c/ha) variant was lower than in the “Biohumus + N60P60K60” variant and was higher in “N60P60K60” and “Control” variants (391.9c/ha, 314c/ha, and 239.8c/ha respectively).
