The effect of different doses of mineral fertilizers and their combinations on productivity of grain and grass crop rotation

On the experimental field Federal Rostov Agricultural Research Center, at the hospital To the Department of Agrochemistry and mineral nutrition of plants in 2015-2017 studied the impact of individual species and fertilizer application rates, both individually and in different combinations, on the productivity of grain (fruit) crop rotation. As a result of the research, a positive effect of each of the studied dosages of fertilizers on the productivity of crop rotation was established. The maximum yield was obtained when introducing a complete mineral fertilizer 42.5 quintals of grain units per hectare, which is 16.3 centners per ha of grain units on hactar more control variant.
