Water use efficiency and economics of Indian mustard (Brassica juncea L.) influenced by drip irrigation and micronutrient application methods

A field experiment was conducted in split plot design with drip irrigation levels (0.4, 0.6 and 0.8 IW/CPE ratios) in main plot and micronutrient application methods (control, soil, foliar and fertigation) in sub plot during Rabi season 2018 at S.K.N. College of Agriculture, Jobner (Rajasthan). The scheduling of drip irrigation at 0.8 IW/CPE ratio recorded significantly higher plant height, dry matter accumulation, siliquae per plant, seeds per siliqua, test weight and seed yield over 0.4 IW/CPE ratio, however remaining statistically at par with 0.6 IW/CPE ratio. Drip irrigation at 0.8 IW/CPE ratio recorded higher net return. Among micronutrient application methods, fertigation significantly increased plant height at 80 days after sowing and at harvest, dry matter accumulation at all growth stages, siliquae per plant, seeds per siliqua and seed yield over all other application methods. Significantly higher net return and B: C ratio was also recorded under fertigation method of micronutrient application.
