Abstract

An experiment was carried out to investigate about the influence of supplementary irrigation and cultivar in MORPHOLOGICAL CHARACTERISTICS of CHICKPEA. The experiment was done in dryland condition at factually of Agriculture, Lorestan University, Khorramabad, Iran with average annual precipitation of 482.42 mm in 2009-2010 farming year. The experiment was conducted split-plot, based on Randomized Complete Bloc Design (RCBD) with three replication an three factors, including supplementary irrigation at four levels including without supplementary irrigation (I0), one time irrigation at flowering stage (I1), one time irrigation at seed formation stage (I2) and Double time irrigation at flowering + seed formation stage (I3) and Tow row spacing (30 and 20 cm). The results of plant growth analysis on the basis of growth degree days (GDD) showed that supplemental irrigation increased dry matter accumulation (DMA), leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) in treatment Double time supplementary irrigation. Through less competitive MORPHOLOGICAL CHARACTERISTICS were highest in 30 Cm row spacing. The results showed that flowering and seed formation stages in CHICKPEA cultivars are sensitive to DROUGHT STRESS.
