A field experiment was conducted during kharif season of 2014-15 on the topic entitled "Phase wise verification of climatic requirement on growth and development in rice cultivars." in sandy loan soil of N.D. University of Agriculture and Technology, Kumarganj, Faizabad (U.P.). The experiment consisted of nine treatment combinations comprised of three transplanting dates viz., I st dates of transplanting on July 5 (D1), IInd dates of transplanting on July 15 (D2) and IIIrd dates of transplanting on July 25 (D3) and three varieties viz., Sarjoo-52 (V1), NDR-359 (V2) and Swarna (V3).

A field experiment was conducted during kharif season of 2014-15 on the topic entitled "Phase wise verification of climatic requirement on growth and development in rice cultivars." in sandy loan soil of N.D. University of Agriculture and Technology, Kumarganj, Faizabad (U.P.). The experiment consisted of nine treatment combinations comprised of three transplanting dates viz., I st dates of transplanting on July 5 (D1), IInd dates of transplanting on July 15 (D2) and IIIrd dates of transplanting on July 25 (D3) and three varieties viz., Sarjoo-52 (V1), NDR-359 (V2) and Swarna (V3). It was observed that different phenophases of rice markedly varied with not only dates of transplanting but also different weather variables which ultimately creates the different crop growing environment to harvest the yield accordingly. As panicle initiation during 10-15 Sept (transplanted on July 15) recorded the highest yield as compared to 2 - 7 September PI stage. Variation in daily mean temperature & solar radiation during reproductive and ripening period also has marked affect. Mean temperature 29.5-300 C during vegetative stage & 26.60C - 28.80C during reproductive stage.
