Abstract:
The field experiment conducted at Agronomy farm, S.K.N. College of agriculture, Jobner during rabi season 2013-14to select appropriate drip irrigation schedule for maximizing productivity and profitability of fenugreek. The experiment consisted nine treatments of irrigation levels and planting pattern viz. Surface irrigation at 1.0 IW/CPE ratio with normal row planting, drip irrigation at 0.4, 0.6, 0.8 and 1.0 IW/CPE ratio with normal as well as paired row planting. The experiment was laid out in Randomized Block Design with three replications. The results showed that drip irrigation at different IW/CPE ratios, except drip irrigation at 0.4 IW/CPE ratio with normal and paired row planting, significantly increased growth parameters, yield attributes and yields over surface irrigation at 1.0 IW/CPE ratio (control). The results further revealed that the drip irrigation at 0.6 IW/CPE ratio with paired row planting, being at par with 0.6 IW/CPE ratio in normal row planting, drip irrigation at 0.8 and 1.0 IW/CPE ratios in normal and paired row planting, recorded significantly higher plant height and dry matter accumulation per metre row length at 40, 80 DAS and at harvest, number of total and effective root nodules and pods per plant (28.72) over drip irrigation at 0.4 IW/CPE ratio with normal and paired row planting. Results further revealed that the drip irrigation at 0.6 IW/CPE ratio with paired row planting, being at par with 0.6 IW/CPE ratio in normal row planting, 0.4 IW/CPE ratio in paired row planting, 0.8 and 1.0 IW/CPE ratios with normal and paired row planting, recorded significantly higher seeds per pod, pod length and N content in straw over 0.4 IW/CPE ratio with normal row planting. The further examination of data indicated that the irrigation at an IW/CPE ratio 0.8 with paired row planting, being at par with 0.8 IW/CPE ratio in normal row planting and 1.0 IW/CPE ratio with normal and paired row planting, recorded significantly increased number of branches per plant and total chlorophyll content over drip irrigation at 0.4 and 0.6 IW/CPE ratio with normal and paired row planting. Results further revealed that the drip irrigation at 0.6 IW/CPE ratio with paired row planting, being at par with 0.6 IW/CPE ratio in normal row planting, 0.4 IW/CPE ratio in paired row planting, 0.8 and 1.0 IW/CPE ratios with normal and paired row planting, recorded significantly higher seeds per pod and pod length over 0.4 IW/CPE ratio with normal row planting. Application of drip irrigation at 0.6 IW/CPE ratio with paired row planting proved to be best treatment in terms of growth and yield.
