Abstract: A field experiment was carried out at Agrometeorological Research Farm, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya (U.P.) during kharif season of 2021-22 and 2022-23 to study the effect of crop growing environment on growth and Development of kharif maize (Zea mays L.) cultivars. The experiment comprised nine treatment combinations and conducted in Randomized block design and replicated four times. Treatment consisted of three crop growing environment viz. 1^st July, 11^th July and 21^st July with three cultivars viz, Shweta, type-41 and Tarun. Results reveal that Plant height (cm), dry matter accumulation (gm^-2) and leaf area index increased significantly at all the stages of crop growth except 15 DAS. Highest values are recorded with the crop growing environment on 1^st July followed by 11^th July. Lowest values of all were recorded on 21^st July of crop growing environments. Among the varieties, Shweta took a relatively longer duration and ultimately matured 4 days delayed over Tarun and Type-41 when it was sown on 1st July crop growing environment. This study may help to select the suitable sowing time under climatic condition of eastern Uttar Pradesh.
