Abstract

Field experiment was conducted during 2006–2007 to study the effect of phosphorus management in greengram-safflower sequence in a Vertisol. The twelve treatments and three replications designed in RBD consisted of 100% RDF (20: 40: 20 NPK kg/ha to greengram and 25: 25: 25 NPK kg/ha to safflower), 50% recommended P, No P, 50% recommended P + PSB (25 g/kg seed), 5tFYM/ha, 5tFYM/ha + PSB applied in various combinations to greengram in kharif and safflower in rabi season. The results indicated that application of 100% recommended P along with recommended N and K significantly enhanced the yield of greengram and safflower. However, these results were comparable with application of 50% P (20 kg/ha to greengram and 12.5 kg/ha to safflower) + PSB along with recommended dose of N (20 kg/ha to greengram and 25 kg/ha to safflower) and K (20 kg/ha to greengram and 25 kg/ha to safflower) to greengram and safflower in crop productivity with higher nutrient uptake and apparent nutrient balance. The higher P use efficiency was observed with the application of 50% recommended P to both the crops alongwith PSB.
