Response of pigeonpea (Cajanus cajana) to drought management practices under rainfed conditions

Arjun Sharma, Pandit S. Rathod, Mohan Chavan

Abstract


A field experiment was conducted during the rainy (Kharif) seasons of 2006, 2007 and 2008 at Agricultural Research Station, Gulbarga, University of Agricultural Sciences, Dharwad (Karnataka) on shallow black soils to know the effect of different drought mitigation practices on pigeonpea. There were 20 treatment combinations comprising of different drought mitigating practices with 3 replications. Results of pooled data indicated that application of 100% RDF along with FYM @ 5 t ha-1 + opening of shallow furrows between two rows recorded significantly higher seed yield (16.35 q ha-1), stalk yield (45.48 q ha-1), gross returns (Rs. 40,875 ha-1), net returns (Rs. 31,434 ha-1) aand B:C ratio (3.32).  However, it was on par with application of 50% RDF + FYM @ 5 t ha-1  + opening of shallow furrows between two rows for stalk yield (43.94 q ha-1), net returns (Rs. 27,667 ha-1) and B:C ratio (3.08). Significantly lower seed and stalk yield, gross returns, net returns and B: C ratio were recorded in the treatment receiving only 50 % RDF. Further, morphological parameters also showed that crop grown with the application of 100% RDF and FYM @ 5 t ha-1  + opening of shallow furrows between two rows maintained higher growth parameters indicating that crop did not show any moisture stress as compared to application of 50% and 100% RDF only.
