Abstract:

A field study was undertaken in Pakistan during rabi 2002-03 to evaluate newly developed chickpea genotypes (CM-98, 92A048, 93A111, 92A207, 93A086, 92A217, 92A186 and PC2000) under water application and rain-fed management system. Highly significant differences were observed between genotypes and between two management practices for all the traits except primary branches per plant, which were non-significantly different between two managements. The interaction between genotypes and managements (G × M) was non-significant for number of primary branches and number of secondary branches. The yield and most of the yield components were improved with the application of irrigation. On average basis 48% increase in number of pods per plant, 36% in total dry weight and 17% in grain yield was recorded due to irrigation. On the contrary, the grain size was reduced by 16% and the number of primary and secondary branches remained un-affected due to irrigation. The genotype 93A086 with grain yield of 14.37 g per plant was better under irrigation while 92A207 with grain yield of 12.60 g per plant performed better under rain-fed planting. It may be inferred from the present study that any genotype that responds positively to irrigation with respect to seed size coupled with increase in number of pods per plant will be most suitable for irrigated areas.
