Evaluation of yield and productivity indices in planting ratios of chickpea (Cicer arietinum L.) and canola (Brassica napus L.) intercropping
Abstract:   (4598 Views)
To evaluate yield and productivity indices of chickpea and canola intercropping with different planting ratios, a field experiment was conducted in randomized complete block design with four replications at Agricultural Research Station of Mazandran province in Ghaem-Shahr, in 2010. The planting ratios were 0:100, 25:75, 50:50, 75:25 and 100:0 (chickpea: canola) using replacement method. Results showed that intercropping had significant effect on yield and some yield components of both crops. The number of branch and silique.plant-1, 1000-seed weight and grain yield of canola as well as shoot height, number of pod.plant-1 and kernel yield of chickpea were significantly affected by different planting ratios. Calculation of land equivalent ratio (LER) revealed that planting ratio of 50:50 (LER= 1.26) and 25:75 (canola- chickpea) (LER= 1.18) had the highest efficiency by 26% and 18%, respectively. Canola in the planting ratio of 50:50 had the highest relative crowding coefficient (KB= 2.36) as dominant crop and chickpea had the least RCC (KC= 0.72) in the ratio of 75:25 (canola- chickpea) as the in dominant crop. Results also indicated that the interference type was positive and complementary and the observed yield of canola and chickpea were not different from their expected yields in all planting ratios. It is concluded that increased number of branches and siliques.plant-1 in canola, in intercropping with chickpea, were the main reasons of yield benefit.
