A field experiment was conducted to study the determination of crop age based on leaf number and photosynthetic rate was under taken at the Agricultural College farm, Bapatla duringrabi 2016-17. The experiment was laid out in randomized block design with six maize hybrids as treatments in four replications. The stage at which the reproductive growth was attained in all maize hybrids, based on number of leaves expanded on the stem at 42DAS, vary among hybrids differently. Pinnacle (V12-12.50), DKC9142 (V12-12.25), DKC 9042 (V12-12.00), 900MGOLD (V11-11.75) and DKC 9081 (V11-11.50).The hybrids DKC 9142 (36.35) and Pinnacle (36.30) continued its dominance of significance in net photosynthetic rate till 63DAS. However, the maximum net photosynthetic rate was recorded among all maize hybrids during crop growth period at 70DAS ranged from 37.80 to 39.95 but all hybrids are at a par in Pn values.
