A field experiment was conducted during the rainy (Kharif) seasons of 2015 and 2016 at the Main Agricultural Research Station (MARS), University of Agricultural Sciences Dharwad, Karnataka, India. The treatments were laid out in a split plot design wherein three dates of sowing i.e., I-FN June, II-FN June, and I-FN July (DS1, DS2, and DS3) with four improved but currently cultivated with a medium maturity group of maize hybrids (Nithyashree, NK-6240, GH-0727, and 900-M-Gold) i.e. (H1, H2, H3, and H4) were included. Date of sowing (DS) and hybrids (H) were allotted to main and sub plot, respectively. The soil of the experimental plot was clay in texture. Crop phenology, growth and yield component data were collected, and analysed using SAS version 9.3. The highest plant height (192.9 cm) at harvest was recorded by NK-6240. The highest LAI of 4.53 was recorded during DS2, but was on par with DS3. The highest grain number per cob of 354.8 was recorded by DS2 followed by DS2 which recorded 347 grain per cob. The highest total shoot biomass (187.9q ha-1) and grain yield (94.8 q ha-1) were recorded by DS2. But almost similar total shoot biomass (TSB) values were recorded by DS1 and DS3 as well. Among the tested hybrids the highest grains per cob (367.7) was recorded by 900-M-Gold. With respect to hybrids the highest TSBH total shoot biomass per hectare (194. 8 q ha-1) and grain yield (96.8 q ha-1) were recorded by NK-6240 and 900-M-Gold, respectively, but the total shoot biomass was on par with 900-M-Gold.

Key words: Date of sowing, Hybrids, LAI, Biomas, Grain yield.
