| Summary: | Abstract The article presents the research results of the effect of vermicompost based on horse and cattle manure on the productivity of tomatoes in Yakutia. The conducted experiments have established that only half of the manure (50%) is converted into biohumus from all processed raw materials. Fertilizing with the obtained vermicompost helps to improve the properties of greenhouse soil mixtures. It was found that fertilizers help to optimize the physical properties of soils, while increasing the microbiological activity in the soil. The vermicompost derived from horse manure in the composition of greenhouse fertile soils contributed to better development of tomato seedlings. When fertilizing with the vermicompost the best development of seedlings up to 10-30% is noted. Further increase of biofertilizers application inhibits the development of plants, reducing their biometric indicators. The experiment also studied the effect of increasing doses of vermicompost from 100 to 500 g / plant when applied locally. The efficiency of the lowest application dose of vermicompost 100 g / plant (6.2 kg / m 2 ), which corresponds to increasing tomato productivity by 8.8%. Further increase in the rate of biofertilizers does not give a significant increase in productivity. Thus, it justifies the vermicompost application for the enrichment of the greenhouse soil and increasing tomato productivity in conditions of Yakutia. |
