INFLUENCE OF INOCULATION OF OAT AND PEA SEEDS WITH BIOPREPARATIONS WHEN USING MINERAL FERTILIZERS IN DIFFERENT DOSES ON THE YIELD AND QUALITY OF GREEN MASS

Abstract

Within three years, the effectiveness of the use of various biological products for inoculation of oat and pea seeds when using mineral fertilizers, as well as their influence on the yield and quality of green mass has been studied. The experiment was laid out at the experimental station of Ivanovo state agricul-tural Academy. The soil is sod-podzolic medium loamy. As a result of the agrochemical analysis of the soil on the experimental site, the content of humus in the soil was 1.7%, mobile phosphorus 190 mg/kg and mobile potassium 156 mg/kg, pH -5.6. Inoculation of seeds with biopreparations was carried out on the day of sowing, before sowing soil treatment mineral fertilizers were introduced, in some variants bi-omineral fertilizer was used. Mineral fertilizers in the form of ammonium nitrate, double superphosphate and potassium chloride were introduced under presowing cultivation according to the scheme of experi-ence. On the day of sowing, oat seeds were treated with extrasol at the rate of 100 ml per hectare. The inoculation of pea seeds previously treated with rizotorfin, was performed with mushroom of arbuscular- vezikuliar mycorrhizae in the dose of 400g. Biomineral fertilizer was prepared by mixing Bisolbifit with mineral fertilizer in the dose of 40 g per 1 kg of fertilizer. According to the results of the research it was found that the combined use of biopreparations for inoculation of pea and oat seeds with phosphorus-potassium and complete mineral fertilizer allowed to obtain a reliable increase in yield and a positive trend was observed to increase the yield and quality of the green mass.
