Abstract
Abstract The effect of chisel plow on corn / Maha cultivar was observed based on some technical indicators, under three plowing depth (14, 16 and 18 cm). The experiments were conducted in a factorial experiment under randomized complete block design with three replications. The 11-13% soil humidity was meaningfully best than 13-15% soil humidity in all studied parameters. For 11-13% soil humidity and 14cm plowing depth, the fuel consumption, machine efficiency, germination percentage, plant height, 1000 – weight grain, number of grains per ear and the corn productivity were 12.336 and 11.913l.ha −1 79.425 and 79.972 %;89.527 and 92.346 %; 148.85 and 153.70 cm; 218.85 and 226.58 g; 474.308 and 499.354 grain; 4.163 and 4.286t.ha −1 .
