ارزیابی توان رقابتی کنجد (L. Sesamum indicum) و ماش (Vigna radiata L.) در دو بوم نظام تک کشتی و کشت مخلوط

Abstract

In order to study the productivity and competition ability of Sesame and Mung bean, a field experiment was conducted in Agriculture Faculty of Shahid Chamran University of Ahvaz at 2012. Experimental design was split-plot based of RCB with 3 replications. Main plot included 2 planting patterns and sub-plots included 5 plant density ratios. Our result showed that both 50 & 75 cm inter-rows in 50+50% density ratios had the highest intercrop grain yield, respectively (2.05 & 2 ton/ha) In most treatments, Sesame had the higher grain yield than Mung bean. Increasing of plant density had positive effect on yield improving of both crops. The harvest index (HI) was improved by increasing of inter-row due to increase in grain yield and decrease in biological yield. The LER index was higher than that one in all intercropping treatments that result of priority of intercropping systems than mono cropping systems. Sesame had higher competition ability than mung bean, so this crop was dominant crop in intercropping systems than mung bean.
