Flax productivity in seven-field crop rotation on sod-podzolic light loamy soil by using fertilizers and biopreparation
New experimental data have been obtained in the stationary multi-year field experiment on sod-podzolic light loamy soil in 2016-2017. Actual yields of flax straw and seeds of «Levit 1» flax variety in 7-fields system with different levels of fertilizer doses are calculated using balance coefficients in «Mizorin» biological preparation application and without it. The influence of the mineral nutrition level and biological preparation on the indicators is studied, such as: the number of plants per 1 m2 before harvesting, the total and technical length of stems, the thickness of stems, the average number of fruitcases per plant, the average number of seeds in 1 fruitcase, the mass of 1000 seeds.
The productivity of winter rye on sod-podzolic light loamy soil by using fertilizers and a microbiological preparation
The results of field research conducted on soddy-podzolic light loam soil in the Vologda region established that the use of fertilizers significantly increased the yield of winter rye grain both against the background of the flavobacterin biofungicide and without its use. Depending on the doses of fertilizers and bacterialization with a microbiological preparation, the productivity of straw of winter rye naturally increased, the content of nitrogen, phosphorus, potassium in the production increased, the collection of crude protein by grain and the productivity in feed units increased.
