Weed Management in Sesame Field (Sesamum indicum L) Using Wheat Straw and Tillage or no Tillage Systems

摘要

A field trial was achieved to test the response of weed and sesame crop to use wheat straw and tillage or no tillage systems. The experiment treatments were include; no tillage without straw, tillage without straw, tillage with straw, incorporated with soil and straw as cover crop (no tillage). The result shown that weed density and biomass have high significantly suppression when wheat straw applied as cover crop and without tillage soil compared with soil tillage without straw treatments, while no significant different noticed between treatment that no tillage without straw and tillage with straw incorporated with soil treatments. Using wheat straw as cover crop significantly improved sesame yield and yield components about 50% more than using wheat straw as incorporated with soil treatment and no tillage without straw treatment. This increase in sesame yield can be attribute to amended of capsules number per plant (53.2 capsules) and number of seed per capsule (54.6 seed) compared with 18.1 capsules per plant and 53.6 seed per capsule in tillage without straw treatment . The results of this study have led to the conclusion of possibility using wheat straw hopeful approach to amended sesame planting when used as cover crop.
