Effect of Sowing Methods and Different Levels of Nitrogen on Yield Attributes and Yield of Maize

The field experiment was carried out at Research Farm, Integral University, Lucknow, Uttar Pradesh, India during Kharif season, 2021. The experiment envisages to study the effect of Sowing methods and different Nitrogen levels on yield and attributes of maize crop. The experiment was laid down in the Split Plot Design and the treatments was replicated three times. Among the sowing methods, the maximum length of a cob (18.52 cm) was obtained in the ridge sowing method (S1) while among nitrogen levels the maximum length of cob (19.51 cm) was obtained with the application of 25% N through granular urea + 75% N through Nano-urea (N5). Among nitrogen levels highest number of grains per row (40.76) were obtained in the application of 25% N through granular urea + 75% N through Nano-urea (N5). Seed Index was achieved to be highest in ridge method of sowing(S1) with the application of 25% N through granular urea + 75% N through Nano-urea (N5). Number of grains per cob were highest (385.55) in the N5 treatment among the nitrogen levels treatments. Among sowing methods, the maximum grain yield of 51.75 q ha-1 was founded in the ridge method of sowing. Among nitrogen levels the highest grain yield of 57.76 q ha-1 was obtained in N5 treatment. However, harvest index was found to be non-significant. Ridge method of sowing was found to be most effective than broadcasted method. Application of Nano-urea alone did not give good results. Granular urea along with nano-urea was found to be more effective in maize crop under this region.
