Effectiveness of biohumus under beet in the steppe of Western Siberia

In studies on meadow-chernozem soil of the Omsk region it is established that the joint introduction of vermicompost and mineral fertilizers has a positive effect on productivity of root crops of table beet. The average for years of research yield increase of red beet depending on the dose of vermicompost ranged from 7.66 to 22.95 t/ha With mineral fertilizers in doses equivalent to the increase of a crop of beetroot was of 20.48 to 57.40%. In the best case with the application of vermicompost 8 t/ha yield in average years of research to 65.14 t/ha, and in the variant with mineral fertilizers N64P72K64 - 66.41 t/ha. In the studies the ratio of root: foliage changed, 1.06 to 1.59. The most effective options in terms of a yield of 8 t/ha of vermicompost and N64P72K64 ratio was the smallest of 1.54 and 1.59, respectively, while in control the highest was 1.06. In these embodiments, the content of nitrate nitrogen in soil in the phase of 8-10 leaves was 12.9 and 14.8, mobile phosphorus - 262 and 242, exchange potassium - 823 and 455 mg/kg soil and the control, respectively 8.5, 227 and 392. That is, there is a significant increase in the concentrations of elements in soil. Joint application of organic and mineral fertilizers positive impact on the content of total nitrogen in the roots of table beet. In the phase of cleaning the nitrogen content in the leaves amounted to 0.22-0.57, phosphorus 0.07-0.13%, potassium 0.32-0.47 percent; in the roots, respectively 0.14-0.41, 0.07-0.20 and 0.32-0.47%.
