Agronomic characteristics, yield and yield components of some rain-fed chickpea cultivars by supplemental irrigation

In order to study the effects of some agronomic traits of rain-fed chickpea cultivars on yield and yield components in supplemental irrigation condition, a field experiment was conducted at Mahidasht Agricultural Research Station of Kermanshah province during 2007 croping season. The experimental design was split plot based on randomized complete block design with three replicates, supplemental irrigation treatments including control (I0), Irrigation at 50% flowering (I1) and Irrigation at podding (I2) were considered as the main factor and four chickpea varieties of Bivaniej Local, ILC482, FLIP93-93 and Hashem were arranged in sub factors. Measured traits were plant height, number of pods per branch, number of pods per main stem, number of pods per plant, 100-grain weight, grain yield and grain size. Results showed significant effect of supplemental irrigation on plant height, number of pods per main stem, number of pods per branch, number of pods per plant, number of seeds per plant, grain size, grain yield, 100-grain weight and biological yield. Based on the results, supplemental irrigation at podding stage was the most effective traetment in increasing yield and yield components. Yield and yield components increase were also higher in FLIP93-93 and Hashem cultivar than others.
