Author(s): Pushpanathan KR, BJ Pandian, G Mariappan and P Jeyakumar
Abstract: Field experiments were conducted in farmer’s field at Kokalai village, Namakkal during rabi 2011-12 and 2012-13 to study the effect of drip irrigation regimes and fertigation levels on biochemical characters and castor equivalent yield in castor + onion intercropping system. Experiment was laid out in split plot design with three replications. Castor + onion intercropping system showed significant influence in the biochemical parameters and castor equivalent yield of crops under drip fertigation system. Results revealed that drip irrigation at 80 per cent CPE with application of 100 per cent RDF as water soluble fertilizer (WSF) registered better biochemical characters viz., total chlorophyll; chlorophyll stability index, soluble protein and castor equivalent yield than 60 per cent and 40 per cent CPE during both the years. Whereas water stress at 40 per cent CPE with 75 per cent RDF as conventional fertilizer registered more leakage of cell membrane characters and more proline accumulation, during both the years compared to other treatments
