Effect of irrigation scheduling and thiourea on productivity of Indian Mustard [Brassica juncea (L.) Czern & Coss]

Effect of Irrigation Scheduling and Thiourea on Productivity of Indian Mustard [Brassica juncea (L.) Zern &  Coss] was evaluated at Agronomy Farm, S.K.N. College of Agriculture, Jobner during Rabi season 2019-20. The  experiment consisted of five irrigation scheduling viz., surface irrigation, sprinkler, drip irrigation at 0.4 IW/CPE  ratio, 0.6 IW/CPW ratio and 0.8 IW/CPE ratio, respectively and three levels of foliar application of thiourea  (control, thiourea @ 500 ppm and thiourea @ 750 ppm). The experiment was laid out in split plot design with  three replications. The results revealed that scheduling of irrigation at drip irrigation at 0.6 IW/CPE ratio, was at par with drip irrigation at 0.8 IW/CPE ratio and recorded significantly higher plant height, dry matter accumulation, siliquae per plant, seeds per siliqua, seed yield (2.12 t/ha), straw yield (6.62 t/ha), biological yield  (8.74 t/ha), net returns (` 70,661/ha) and B:C ratio (3.14) as compared to surface irrigation and at 0.4 IW/CPE  ratio. Foliar application of thiourea @ 500 ppm, was found at par with foliar application of thiourea @ 750 ppm,  leading to higher plant height, dry matter accumulation, siliquae per plant, seeds per siliqua, seed yield (1.98 t/ha),  straw yield (6.48 t/ha) and biological yield (8.50 t/ha), net returns (` 66,016/ha) and B:C ratio (3.14) as compared to control. Based on the above findings, drip irrigation at 0.6 IW/CPE ratio with foliar application of thiourea @ 500 ppm could be recommended in mustard crops Rajasthan.
