Abstract:
Winter Wheat is an important cereal crop for the population of Uzbekistan. The objective was to study the effect of different sowing dates, irrigation regime and various levels of fertilization on the growth and development of Asr cultivar of winter wheat. The experiment was conducted on the field №119 of the Dildora-Bojimon farm of Yangibazar district of the Khorezm region during 2014-2016. Statistical analysis of the data showed that different sowing dates, irrigation regime and fertilization levels had a significantly affected on plant height (cm), number of total tillers and number of
productive tillers m-2 of winter wheat.

Abstract:
To evaluate the growth and development of winter wheat under 3 factors (sowing dates, irrigation regimes and rate of fertilization) in Khorezm region,
there was done an experiment using a winter wheat (Triticum aestivum L.) cultivar Kuma. For the experiment we used three sowing dates: D1=1st of
October, D2=10th of October, D3= 20th of October, 2 irrigation treatments, including 60-65-60, 65-70-60 and 2 fertilizaton treatments: the following doses of N150P100K75 kg ha-1 and N200P140K100 kg ha-1 , was conducted in the field №119 of the Dildora-Bojimon farm of Yangibazar district of the Khorezm region during the 2014–2016 growing seasons.
