OPTIMIZATION OF THE MINERAL NUTRITION CONDITIONS OF MUSTARD

The article gives an assessment of one the promising and valuable oilseeds - mustard, cultivation which is provided by program diversification grain production in Kazakhstan, particular, crop production. It was revealed that conditions mineral nutrition mustard steppe zone Northern Kazakhstan were not studied. Therefore, experiments laid to study optimization for mustard. A 14-variant scheme presented create different levels phosphorus nitrogen soil order determine quantitative connection between level nutrients productivity varieties. purpose research (2019-2021) features fertilizer Kazakhstan. Their main directions were: requirements this fertility properties; properties its ability meet needs crops. conclusions suggest all year’s has developed under deficiency soil, average supply nitrogen, increased potassium. application nitrogenphosphorus fertilizers contributed increase content nitrates mobile 2-3 times determined amount applied.
