Abstract:
A field study was executed in rainy seasons of 2017 and 2018 to know the impact of drought management strategies on pigeonpea under rainfed situations. The trial was laid out in randomized block design with three replications. The findings of the investigation revealed that all the drought mitigation techniques resulted superior performance in aspects of growth, yield components and grain yield over check. Highest seed yield of 2448 kg ha-1 was registered with inoculation of VAM fungi @12.5 kg ha-1 and crop residue mulching@ 5 t ha-1 followed by addition of 100% P which was statistically commensurate with VAM fungi @12.5 kg ha- 1 and supply of 100% P (2370 kg ha-1). However, the highest monetary values of gross returns (Rs.1,08,660/-) and net returns (Rs. 72,306/-) were realized with inoculation of VAM fungi @12.5 kg ha-1 followed by crop residue mulching @ 5 t ha-1 and supply of 100% P but B:C ratio was higher (2.03) with VAM fungi @12.5 kg ha-1 and supply of 100% P.
