The mineral fertilizers affect positively on plant growth and development. It was shown that the positive dependence between increased doses of mineral noutrition (in the gap from 0 to 120 kg. per hectare) and the growth of generative and vegetative plant organs. Application of NPK fertilize (120-120-120) was optimal to produce the maximum yield of marketable bulb onion 43.1 tons/hectare, with additional increase 22.8 tons /hectare as compared with standard. Seed plants also produced 1065 kg/hectare of seeds; that was more than 100 % compared with standard.
