An investigation was carried out during kharif 2017 at Department of Agricultural Meteorology, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, entitled “Performance of maize hybrids (Zea mays L.) under different sowing windows” The experiment was laid out in a FRBD design where main plots were assigned to five sowing dates and sub-plots to two Cultivars of maize, with ten treatment combinations and replicated thrice. The treatment comprised the five date of sowing i.e. 25th MW, 26th MW, 27th MW, 28th MW and 29th MW and two cultivars, H1 (Pioneer 3501), H2 (Monsanto 9126). The results revealed that among the five different dates of sowing. D1-25th MW sowing and hybrid H1 (PIONEER-3501) resulted in crop sown with higher growth and yield parameters significantly i.e. Plant height, functional leaves, days to 50% tasseling, days to 50% silking, Number of cob per plant, length of cob, diameter of cob, Number of grain per cob and test weight also first date of sowing D1 25th MW significantly highest grain yield (4969 kg/ha-1) followed by D2 (4816 kg/ha-1), D3 (4627 kg/ha-1) D4 (4424 kg/ha-1) and D5 (4131 kg/ha-1) and among hybrid H1 (PIONEER-3501) (4609 kg/ha-1) and H2 (MONSANTO-9126) (4578 kg/ha-1) respectively. The highest total GDD was observed with D3 27th MW sowing date i.e. 2498.7 0C day and hybrid H2 (Monsanto 9126) i.e. 3008.9 0C day similarly the highest HTU was observed with D3 27th MW sowing date i.e. 13521.2 0C day/hr and hybrid H2 (Monsanto 9126) i.e. 16723.3 0C day/hr. PTU observed during total crop growth period was highest in D4 28th MW i.e. 37321.2 0C day/hr as compare to remaining treatments. In case of hybrid PTU was highest in H2 (Monsanto 9126) i.e. 38283.9 0C day/hr. The highest GDD, HTU and PTU was observed in hybrid H2 (Monsanto 9126) as compare to H1 (Pioneer 3501). In case of date of sowing the highest GDD and HTU in D3 27th MW and PTU was highest in D4 28 th MW.
