Abstract
The study was carried out during the chickpea growing season to study the effect of seed size on yield and yield components of chickpea. Ten chickpea genotypes NKC-5-S13, NKC-5-S24, NKC-5-S17, NDC-122, NDC-4-20-6, NKC-5-S16, KARAK-2, NDC-4-20-1, NIFA-88 and NIFA-95 were used in this study. Randomized complete design (RCBD) was used with three replications. Data were recorded on days to 50% flowering, plant height, primary branches plant-1, secondary branches plant-1, pods plant-1, seeds pod-1, number of seeds plant-1, 100 seed weight, biological yield plant-1, harvest index, leaf area, leaflet leaf-1, seed yield plant-1, seed yield plot-1. Significant differences were observed for all traits. Ranges of different parameters were recorded as 138-149.3 for days 50% flowering, 53.3-67.8cm for plant height, 1.6-4.5 for primary branches plant-1, 4.1-9.7 secondary branches plant-1, 25-69.2 for pods plant-1, 1-1.7 for number of seeds pod-1, 34.8-69.5 for number of seed plant-1, 18.4-31.1g for 100-seed weight, 9.9-40.5g for biological yield plant-1, 29-51.1g for harvest index, 290.1-716g seed yield plot-1, 4.5-20.5g for seed yield plant-1, 3.8-8cm for leaf area and 12-14.9 for number of leaflets leaf-1.The effect of seed size on yield and yield components was significant for most of the traits.
