The experiment consisting of four dates of sowing (15th June, 25th June, 5th July and 15th July) in main plot and five maize (Zea mays L.) hybrids of different maturity group namely, HQPM-1 (long), HM-4 (medium), HM-5 (long), HM-6 (early) and HM-7 (extra early) in sub plot was replicated three times in split plot design. Ten days advance, normal and 10 days delay sowing being at par recorded significantly higher plant height, dry matter, crop growth rate, as compared to delay in sowing by 20 days from normal sowing. Plant population and relative growth rate did not differ significantly due to date of sowing. Among hybrids, HM-5 recorded highest dry matter followed by HQPM-1, HM-4, HM-6 and lowest in case of HM-7. HM-5 recorded higher crop growth rate from 60 DAS to maturity. Days to 50 % tasseling, 50 % silking and maturity were delayed in last date of sowing. HQPM-1 recorded highest plant height at harvest followed by HM-4, HM-7, HM-6 and lowest in HM-5. HM-6 and HM-7 recorded lowest crop growth rate between 60 DAS to harvest. HM-7 and HM-6 took lower number of days to attain 50 % tasseling, 50 % silking and maturity stage. HQPM-1 and HM-5 being at par took higher number of days to 50 % tasseling, 50 % silking and maturity as compared to HM-4.
