Abstract
In this research, effect of tillage and planting methods (planting on permanent raised beds, no-till, and conventional tillage) on soil properties such as bulk density, moisture content, and organic carbon and water consumption, water productivity, and crop yield was evaluated in the form of randomized complete blocks experimental design with three treatments and six replicates in corn-wheat rotation. Results showed that the raised bed planting had the maximum forage corn (95.33 ton/ha) and wheat yield (7.01 ton/ha) and no-till had the minimum silage corn (87.06 ton/ha) and wheat yield (5.23 ton/ha) which had no significant difference with the conventional tillage. Forage corn consumed the maximum water (9531 m3/ha) in the conventional tillage and the minimum water (8155 m3/ha) in no-till; while, there was no significant difference between treatments from the water productivity point of view. Wheat consumed the maximum water (7177 m3/ha) in raised bed planting, but there was no significant difference between treatments from the stand point of water productivity. Results also showed that conservation tillage methods increased soil moisture content in forage corn planting (around 11%), but had no significant effect on the soil moisture content in wheat planting.
