Effect of levels and depth of sprinkler irrigation for chickpea (Cicer arietinum)

An experiment was conducted on chickpea with levels and depth of irrigation water as variables in four replications during Rabi 2006–07 to 2008–09 at Agricultural Research Station, Sriganganagar. The treatments comprising of the combination of 3 levels of sprinkler irrigation (IW/CPE 0.5, 0.6 and 0.7) and 3 depths of irrigation (4, 5 and 6 cm) along with one control treatment of border strip irrigation (As per recommendation). The total ten treatments were replicated four times in Randomized Block Design.On the basis of experimentation, it was observed that under sprinkler irrigation system the seed yield of gram significantly increased with the increase in irrigation level up to IW/CPE 0.6. It increased 1.5% seed yield and saved 9.8% irrigation water over conventional boarder strip irrigation. The maximum water expense efficiency (8.77 kg/ha mm) was also recorded under IW/CPE 0.6. Further, the yield of gram was increased significantly with every increase in the depth of irrigation water. Highest seed yield (23.00 q/ha) was recorded with 6 cm depth.
