Study of the effectiveness of the use of organic fertilizers on forage crops

As a result of two-year studies, a significant effect of granulated organic fertilizer "Greenex" on morphometric indicators and productivity of biomass and seeds of the studied crops was found. The use of fertilizer at a dose of 200 kg / ha proved to be the most effective. So, the pre-sowing application of this dose of fertilizer provided a reliable excess of indicators relative to the control on all variants of the experiment. To improve growth processes, the maximum effect was found in soybeans and grain sorghum. It was revealed that the increase in yield when using fertilizer compared to the non-fertilized control was 12.99-29.33% for crops.
