Evaluation of Some Important Indicators of Silage Corn Production in No-Tillage Systems

Abstract

Conventional tillage increases soil compaction and 25% water and wind erosion. It also causes decrease soil porosity and water capacity. In order to prevent this situation; conservational tillage is considered as an effective strategy. Conservational tillage have important role in soil erosion and improve its quality. Every year Moghan Agro-Industrial & Livestock (MAIL) Company costs a lot to do conventional tillage. In order to achieve the objectives of this study, an experiment was conducted in factorial pattern with completely randomized design with two factors, tillage method (Conventional tillage & No-tillage) and irrigation method (traditional irrigation & Sprinkler irrigation). Results showed that yield, average fuel consumption, traffic, water consumption and fuel consumption productivity index in No-tillage method is better than conventional tillage. Also, the results of the MCDM Engine software showed the Combination of No-tillage system with Sprinkler irrigation with CL*=0.98 (The relative proximity of the option to the ideal solution) is best method for minimum cost of production and maximum yield in silage corn. Therefore, No-tillage system with Sprinkler irrigation can be suitable method for sustainable production of Silage Corn in Moghan region.
