A field experiment was conducted during rabi season, 2013 to study the effect of different IW : CPE ratios and crop geometry on yield and economics of maize. The IW: CPE ratio of 1.0 produced significantly higher grain and stover yield which was at par with I2 (IW: CPE ratio of 0.8). With regard to crop geometry, significantly higher grain yield was obtained at a spacing of 30/90 × 20 cm, whereas higher stover yield was obtained at a spacing of 60 × 15 cm. The highest B:C ratio was obtained at IW:CPE ratio of 1.0 with a spacing of 30/90 × 20 cm.
KEY WORDS: Crop geometry, Irrigation, Rabi maize,
