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.

Ушбу изланишнинг мақсади Хоразм вилояти шароитида кузги буғдой Аср навининг ўсиш ва ривожланишини ҳар хил экиш муддатлари, суғориш тартиблари ва ҳар хил ўғит меъёрларига боғлиқ ҳолда ўзгариши таҳлил этиш ва ўрганиш. Дала тажрибаларини Хоразм вилоятининг Янгибозор тумани «Дилдора-Божимон» фермер хўжалиги №119 контур рақамли ер майдонида 2014-2016 йилларда ўтказилди. Статистик тахлил натижаларига кўра хар хил экиш муддатлари, суғориш тартиблари ва ўғит меъёрлари кузги буғдойнинг бўйига, умумий ва маҳсулдор поялар сонига сезиларли таъсир кўрсатади
