Effects of supplemental irrigation on Chickpea (Cicer arietinum L.) yield in Low rain condition

An experiment was carried out in 2008 to investigate the effects of different irrigation regimes, and Chickpea cultivars on chickpea production in the Khorramabad Lorestan. The experiment was split–plot in a randomized complete block design with 3 replications. Supplementary irrigation AT 8 levels (1-rainfed without irrigation, 2-Irrigation after Sowing, 3-Irrigation at flowering, 4-Irrigation at pod fill, 5-Irrigation at Sowing+flowering, 6-rrigation at Sowing+pod fill, 7-Irrigation at flowering+pod fill, 8-Irrigation at Sowing+flowering+pod fill) was allocated to main plots, and the genotypes (Filip 93-93, Hashem, and Greet) was allotted to sub plots. Chickpea yield components was measured base on the 10 randomly selected plants from each plot, and grain yield was determined base on the middle rows of each plot. Among irrigation treatment the highest grain yield per area (762.2 kg/ha) was belonged to irrigation at sowing+flowering+pod fill. Three times irrigation treatment in comparison to rainfed increased grain yield per area by 251.7%. This is show the importance of supplementary irrigation for increase of chickpea yield. Among chickpea cultivars the highest level of grain yield per area (701.8 kg/ha) was achieved for Greet mass. Grain yield for Hashem cultivar was very low. In conclusion, Hasher cultivar dose not recommended for spring crop in regions with climatic condition like Lorestan, but Filip had appropriate compatibility.
