An experiment was conducted at the Agriculture Research farm of the Arunachal Universities of Studies, Namsai, Arunachal Pradesh during rabi season 2018-19 to study the response of different maize varieties to the planting densities. The experiment was conducted with twelve treatment combinations comprising of four planting densities viz., S1 (70cm x 20cm), S2 (60cm x20cm), S3 (50cm x 20cm), S4 (40cm x 20cm) and three varieties V1 (Bond NMH 007), V2 (HQPM-1), V3 (Local) in a split plot design with three replications. The results revealed that the variety Bond NMH 007 was superior to other varieties. Although maximum plant height (220.35cm) was observed in the Local variety whereas the other growth parameters were found to be the highest in variety Bond NMH 007 such as number of leaves (10.83), number of cobs (2.00), ear diameter (16.70 cm), cob length (21.53 cm), 50% tasselling (85.79), fresh weight (181.33 g), dry weight (141.78 g), number of seed per cob (315.96), grain yield per plant (126.37 g) and grain yield per plot (2.24 kg). Among different planting densities S1 (70cm x 20cm) recorded highest value for plant height at 120 days after planting (191.47cm), diameter of ear per plant (15.92cm), cob length per plant (20.58cm), days to 50% tasselling (81.22 days), number of seed per cobg (286.83). Fresh weight per cob (175.75g), dry weight (137.22g) and highest grain yield per plant(119g). The results also showed that planting density S1(70cm x 20cm) with V1(Bond NMH 007) variety obtained highest value for most of the parameters.
