Abstract: In order to understand the effects of different planting patterns on agronomic characters and yield and provide the reference for high yield level planting of sesame.Six treatments including single ridge with sowing before mulching(T1),single ridge with mulching before sowing(T2),double ridges with sowing before mulching(T3),double ridges with mulching before sowing(T4),double ridge without mulding(T5) and flat-planting(CK) were disigned with sesame cultivar Jizhi128.Experimental data were analysed using GGE biplot.The results showed that sesame agronomic characters and yield appear significant differences in different planting patterns,among which the treatment of T3 and T4 were the best planting pattern for sesame.The sesames stem diameter were wider,first capsule height were lower,green leaf number were more,leaf fallen height were lower,infertile top length were shorter,disease index were less,capsules per plant were more,1 000-seed weight were heavier and seed yield per plant were higer in T3 and T4 treatments than others.GGE biplot can show the best treatment in fig and provide an effective method to select planting patterns
