Abstract


A field experiment was conducted during rabi seasons 2010 and 2011 on clayey soil of Junagadh (Gujarat) to study the response of sweet corn (Zea mays L. var. saccharata Sturt) to irrigation (0.6, 0.8 and 1.0 IW:CPE) and fertilizer (control, 90-45, 120-60 and 150-75 kg N-P2O5/ha). The results revealed that irrigation at 0.8 IW:CPE being at par with 1.0 IW:CPE enhanced growth and yield attributes and thereby green cob and fodder yield along with higher net returns and B:C ratio over irrigation at 0.6 IW:CPE. Application of 120-60 kg N-P2O5/ha being at par with 150-75 kg N-P2O5/ha improved growth and yield attributes and ultimately higher green cob and fodder yields with higher net returns and B:C ratio over control and 90-45 kg N-P2O5/ha. Therefore, irrigation at 0.8 IW:CPE and fertilizer dose of 120-60 kg N-P2O5/ha could be applied for higher yield and economical realization from rabi sweet corn along with appreciable saving of water and fertilizer under climate change conditions.
