Abstract:

Field experiments were conducted at Department of Agronomy of Tamil Nadu Agricultural University, Coimbatore. The main objective of the study is to evaluate various planting pattern and nitrogen scheduling approaches on yield attributes, yield and harvest index of maize. The experiments were laid out in split plot design and replicated thrice. Main plots treatments comprised of spatial pattern viz., 60 x 25, 30 x 30, 35 x 35, 40 x 40, 45 x 45 and 50 x 50 cm. Three nitrogen scheduling approaches were assigned to sub plots. Fixed growth stage based N scheduling approaches were compared with Leaf colour chart based (LCC) N management. The results of the study revealed that planting at 35 x 35 cm resulted more number of grain rows cob-1 (15.1 and 15.4). Whereas other yield attributes like of grains row-1 (34.04 and 34.53), of grains cob-1 (522 and 531) and test weight (42.27 and 44.97) were maximum under 50 x 50 cm pattern. LCC based N scheduling significantly increased the yield attributes. Outcome of this study indicated that spatial pattern of 35 x 35 cm with LCC based N management recorded maximum grain yield (11292 and 11558 kg ha-1), than other treatments.
