A field experiment was conducted during rabi 2016-2017 on silty loam soils at Agronomy Research Farm, Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) to study the “Agro-physiological attributes of maize as influenced by Planting geometry and Moisture regimes”. The experiment was laid out in split plot design with four planting geometries viz., 60× 10 cm, 60 × 15 cm, 60 × 20 cm, 60 × 25 cm and four moisture regimes viz., 0.6 IW/CPE ratio, 0.9 IW/CPE ratio, 1.2 IW/CPE ratio, 0.9 IW/CPE ratio up to silking and 1.2 IW/CPE ratio for rest of the crop season which were replicated thrice. Results showed that higher plant height (cm) and leaf area index (LAI) at harvest was recorded with 60 × 10 cm planting geometry and 1.2 IW/CPE ratio which was statistically at par with 60 × 15 cm and 0.9 IW/CPE ratio up to silking and 1.2 IW/CPE ratio for the rest of the crops season. Dry matter accumulation (g m-2), stem girth (cm) at harvest was higher in 60 × 25 cm and 1.2 IW/CPE ratio which was at par with 60 × 20 cm and 0.9 IW/CPE ratio up to silking and 1.2 IW/CPE ratio for the rest of the crop season. Number of days taken for 75% tasselling, silking and maturity was lower with 60 × 25 cm and 1.2 IW/CPE ratio while higher with 60 × 10 cm and 0.6 IW/CPE ratio. Interactive effect of planting geometry and moisture regimes on Agro-physiological attributes under study were found to be non-significant.
