Study is devoted to definition of cotton water consumption regularities, reclamation and weather parameters and parameters of cotton development during vegetation for preparation of model to predict cotton irrigation schedule in Hunger Steppe new development zone. Climate-continental; relief-hilly alluvial plain; soils-loess-like loam, slightly saline. Ground water table is 1.5-3. 5m. Irrigated area under cotton is ISOOha, area of plot is lOha. Irrigational canal is lined by concrete slabs. Plot is equipped with means of measurement. Multiyear study allowed to calculate average for decade air temperature and humidity, wind speed, soil temperature, total evaporation, radiation balance, turbulent heat exchange and heat influx into the soil as well as cotton development parameters that allows to predict moisture distribution in root zone by mathematical model and operative regime of irrigation for one-two decades. Results are recommended for practical application.

Key words
