Field experiments were conducted at eastern block farm, Tamil Nadu Agricultural University, Coimbatore during kharif 2022 and rabi 2022-2023 seasons to find out the effect of different nitrogen levels and spacing on the growth and yield attributes of maize. The field trials were laid out in split plot design with three replications. Main plots different nitrogen levels viz., N1, N2, N3 and different spacing viz., S1, S2 were taken as subplot. The results revealed that different nitrogen levels and spacing had significant influence on growth and yield attributes of maize. Higher values of plant height were recorded with S1- 45 25 with N3-125% RDN during the kharif and rabi season. Yield parameters viz., cob length, cob girth, cob weight, number of grains per cob, and 100 grain weight were higher under S2-60 25 with N3- 125% RDN when compared to other treatments.
