ABSTRACT
An experiment was conducted during rabi season on Vertic Ustochrepts of Navsari (Gujarat) with three levels each of irrigations and mulches to study the effect on growth parameters, yield attributes, yield and economics of castor cultivation. In almost all cases 0.8 and 0.6 IW/CPE ratios were at par but both were significantly superior to 0.4 ratio. Irrigation scheduled at 0.8 IW/CPE recorded higher seed yield of 2803 kg/ha but it was at par with 0.6 IW/CPE (2677 kg/ha). Mulching with black plastic showed it's superiority over sugarcane trash mulch and unmulched control in almost all the characters. Significantly higher seed yield was obtained with black plastic mulch treatment (2745 kg/ha) which was followed by sugarcane trash mulch (2501 kg/ha). Irrigation scheduled at either 0.6 or 0.8 IW/CPE with 60 mm depth was found more remunerative than at 0.4 IW/CPE ratio. Similarly, mulching with sugarcane trash recorded higher net profit Rs 29035/ha as compared to rest of the mulching treatments.
