Abstract: Studies of growth and yield were carried out on onion hybrids Banco F1, Hilton F1, Exacta F1, Gladstone F1, Rossa de Ference F1, Manas F1 in 2008-2015. The soil of the experimental plot humus contained 0,62-1,26%. Studies have shown that the formation of a crop of onion is deficiency mainly nitrogen and phosphorus. Examining the growth of onion at different stages of ontogenesis has shown a change in its speed even under optimal growing conditions. The growth rate is determined by the thermal regime of the beginning of growing season. In cold prolonged spring growth and slow down development somewhat. But at the beginning of summer crops is rapidly increasing vegetative mass. The original method developed of forecasting of productivity of onion presented on light-chestnut soils. The influence identified of factors aggravating the conditions for plant growth in intensive technologies. Predictive model is calculated on the basis of long-term data on education of herbal weight. They allow to prove necessity of use of means which reduce the effect of stress and to identify the efficiency of production of hybrid plants of different maturity.
