| In order to evaluate the effect of different levels of irrigation and plant density on grain yield and its components in chickpea cv. Kaka, a field study was conducted at Research Field Station of Agricultural Faculty, Mohaghegh Ardabili University during 2006 cropping season. Treatments were arranged as split plot in randomized complete block design with three replications. Different irrigation levels (full irrigation, irrigation to flowering stage, irrigation after flowering stage and no-irrigation) were assigned to main plots and sub-plots comprised of different plant densities (16, 32 and 64 plants/m2). Results showed that irrigation and density levels significantly affected pod number per plant, 1000-grain weight, grain yield per unit area and harvest index. Number of pod per plant, 1000-grain weight, grain yield and harvest index were greater in full irrigation and irrigation to flowering stage in comparison to other irrigation levels. Grain yield per plant, pod number per plan, 1000-grain weight and harvest index were greater at 16 and 32 plants/m2 in comparison to 64 plants/m2. In contrast, grain yield per unit area at 64 plants/m2 were significantly greater than other plant densities. Interaction of irrigation × plant density indicated that the highest and the lowest grain yield was achieved in 64 plants/m2 in full irrigation and no-irrigation. However, there was not significant difference between 64 and 32 plants/m2 in no-irrigation treatments. It is concluded that irrigation to flowering stage and 64 plants/m2 produced reasonable grain yield under the conditions of this study. |
