The field experiment was conducted during kharif season of 2016 on deep black soil at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, Karnataka, India under potential condition. The experiment consisted of 36 maize hybrids (21 private and 15 public sourced) replicated twice and laid out in Randomised Complete Block Design. The phenology, leaf area index, yield traits and grain yield were recorded and statistically analysed for comparison amongst the hybrids. The study showed that private hybrids outperformed the public hybrids in both growth and yield parameters. The private hybrids had mean LAI value of 2.26, 4.27 and 2.51 at 30 DAS, 70 DAS and at harvest compared with mean LAI values of 1.85, 3.54 and 1.59, respectively, by public hybrids. The highest grain yield among the private hybrids was recorded by DKC-9141 (11492 kg ha-1) compared to the highest among public hybrid GH-15305 (9227 kg ha-1), and the difference was 19.8 per cent. The lowest yield of 6631 kg ha-1 was recorded by a public hybrid GH-1314 which was 22.1 per cent lower than the lowest yield of 8511 kg ha-1 recorded by the private hybrid NMH-145.
