Abstract:
A field experiment was conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner, Jaipur (Rajasthan) during rabi season of 2018-19 to study the effect of micro irrigation scheduling on growth, yield attributes and grain yield of barley. The experiment comprising of eight treatments of irrigation viz., flood, sprinkler and drip irrigation at 0.4, 0.6 and 0.8 IW/CPE ratios with 2 and 4 days interval was laid out in randomized block design and replicated thrice. The results showed that drip irrigation at different IW/CPE ratios, except drip irrigation at 0.4 IW/CPE ratio with 2 and 4 days interval, significantly increased growth parameters, yield attributes and grain yield of barley. The results further revealed that the drip irrigation at 0.8 IW/CPE ratio with 4 days interval, being at par with 2 days interval at same IW/CPE ratio, recorded significantly higher plant height at 80 DAS and harvest and dry matter accumulation per metre row length at 40, 80 DAS and at harvest, number of total tillers at 80 DAS and harvest and number of effective tillers/m row length (75.19), number of grain/spike (51.47), spike length (13.66), test weight and grain yield (55.51 q/ha) over lower IW/CPE ratio of drip irrigation as well as flood irrigation.
