ABSTRACT
A field was conducted at Agronomy Instructional Farm, S.D. Agricul. University, Sardarkrushinagar during semi rabi 2013-14 and 2014-15 to find out a suitable irrigation scheduling and sources of nitrogen fertigation under north Gujarat conditions. The experiment comprised of four scheduling of irrigation (0.6 ADFPE, 0.8 ADFPE, 1.0 ADFPE) through drip system and surface method and three nitrogen fertigation (N1 : 50 % RDN, N2 : 75 % RDN and N3 : 100 % RDN (i.e. 80 kg/ha), thereby making twelve treatment combinations. The result revealed that to achieve profitable yield from semi rabi castor, follow irrigation at 1.0 ADFPE through drip in conjunction with fertigation of nitrogen @ 60 kg/ha through urea in four equal splits at 30, 60, 90 and 120 DAS, respectively. Additional 20 kg/N/ha along with 40 kg P2O5/ha need to be applied before sowing the crop.
