Irrigation levels influenced on morphophysiological characters of chickpea (Cicer arietinum L)

Abstract An experiment was conducted at the Research farm and laboratory of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur during November 2012 to April 2013 to evaluate Morpho-physiological attributes, of Chickpea (Cicer arietinum L.) varieties affected by irrigations levels. The experiment was laid out in split plot design with three replications. Four irrigation levels {I0-No irrigation (control), I1-30 mm irrigation one at pre-flowering stage, I2-30 mm irrigation one at pod formation stage and I3 (30+30=60 mm irrigation one at pre-flowering stage and one at pod formation stage } were considered as main plot treatment and three chickpea genotypes (Barichhola-6, Barichhola-7 and Barichhola-9) were considered as sub plot treatment. Experiment showed that most of the morpho-physiological characters such as plant height, number of branches plant-1, number of leaves plant-1, MRC, RLWC, chlorophyll content, number of total flower plant-1, number of effective flower plant-1 and distance from 1st pod to soil surface increased significantly due to application of irrigation. The above parameters were the maximum when the chickpea varieties were treated with I3 followed by I1 then I2 over the control. But proline content increased due to lake of irrigation and I0 produced the maximum proline content.
