The study was conducted in the instructional and research farm during the period 10th February to 11th September 2023 in a randomized block design (RBD) method. The first sowing dates started on 10th February, followed by 20th February, 2nd March, 12th March, 22nd March, 1st April, 11th April, 21st April, 1st May and 11th May, respectively, at 10 days intervals.  The growth parameters like seed germination, number of leaves per plant, plant heights, number of cobs per plant, number of grains per cobs, 100 grain seed index, leaf area index and grain yield per hectare has been observed and evaluated. On evaluation it was noted that maize sown on 1st April gave highest seed germination of 95.87%, tallest plant of 198.83 cm, maximum number of 20.33 leaves per plant, highest leaf area index of 582.56, maximum number of 8.00 cobs per plant, maximum number of 31.27 grains per cob, highest seed index of 41.33 and highest grains yield of 9.31 kg/plot when compared to all other sowing dates. The germination (r= 0.704), plant height (r= 0.641), number of leaves (r= 0.966), leaf area (r= 0.709), number of cobs per plant (r= 0.994), number of grains per cob (r= 0.698) and seed index (r= 0.968) are positively stimulated yield response in hybrid maize. Thus, sowing on 1st April has a paramount effect on the production of hybrid maize in Namsai conditions. Further study may be needed to investigate precise sowing dates of local maize in the Namsai region.

Keywords: Maize, growth parameters, yield, correlation, sowing dates.
