Studies on the effect of crop growing environment on growth and yield of Kharif maize (Zea mays L.) cultivars

A field experiment was carried out at Agrometeorological Research Farm, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj- Ayodhya (UP) during kharif season of 2019 to study the effect of crop growing environment on growth and yield of kharif maize (Zea mays L.) cultivars. The experiment comprised of nine treatment combinations and conducted in Randomized block design and replicated four times. Treatment consisted of three crop growing environment viz. 5th July, 15th July and 25th July with three cultivars Viz, Kanchan, Azad hybrid-1 and Azad hybrid-2.Results reveal that Crop growing Environment of 5th July (100000 plants ha-1) was found suitable for optimum growth and yield of Kharif maize. Among crop growing environments on 5th July recorded higher days taken from sowing to maturity. Crop growing Environment on 5th July and cultivar Kanchan recorded higher heat use efficiency from sowing to maturity of Kharif maize.
