Student of Agricultural Mechanization, Department of Biosystems Engineering, Faculty of Agriculture, Shahid Chamran University of Ahvaz, Ahwaz, Iran Nasim Monjezi Assistant professor, Biosystems engineering Dept., Faculty of Agriculture, Shahid Chamran University of Ahvaz, Ahvaz Afrasiab Rahnama Ghahfarokhi Associate professor, College of Agriculture, Shahid Chamran University of Ahvaz, Ahvaz,Iran Mohammad Javad Sheikhdavoodi professor, Biosystems engineering Dept., Faculty of Agriculture, Shahid Chamran University of Ahvaz, Ahvaz, Iran Journal Article 2021 01 06 Background & objective Nowadays demand for producing agricultural products has been increasing. So to investigate the effect of tillage and planting pattern using crop residue for corn forage a research was carried out in the research field of in the Dezful city of Khuzestan province. <br />Methods & Materials A split strip plot design was applied using 3 replications based on randomized complete block design. Treatments tillage methods at three levels (tillage, minimum tillage and no-tillage) was as the main factor and management of wheat residues (Chamran cultivar) at two levels (maintaining residues standing and removing all crop residues from the soil surface) was as a secondary factor.<br />Results The results were shown that conventional tillage under no residue and no-tillage under residue condition product the most and the least emergence rate of 3.73 and 1.96 respectively. Also conventional tillage under no residue used 10230 m3/ha compared to no-tillage covered by residue 6341 m3/ha (p≤0.01).No-tillage with an average of 2.74 and conventional tillage with 2.19 kg/m3 showed the highest and lowest physical efficiency of water consumption, respectively (p≤0.01).<br />ConclusionThe use and development of conservation cultivation systems (especially minimum tillage) in corn can help maintain conservation of production resources such as water, soil and the environment. The use of conservation tillage systems along with the preservation of residues at the soil surface, increasing moisture storage, reducing irrigation water consumption, increasing soil organic matter and fertility and saving labor and time spent on tillage operations can be a model suitable for planting corn.
