A field was conducted at Experimental Farm, Agronomy Section, College of Agriculture, Latur. The experimental field was levelled and well drained. The soil was medium and black in colour with good drainage. The soil was clayey in nature and slightly alkaline (7.8) in reaction, low in nitrogen (118.86 kg ha-1), medium in available phosphorus (17.7 kg ha-1) and rich in available potassium485.89 kg ha-1). The environmental conditions were favorably congenial for normal growth and maturity of pigeonpea crop. The experiment was laid out in Factorial Randomized Block Design with two factors and replicated thrice. Whereas first factor comprises levels of phosphorus viz., 0 (control), 40, 50 and 60 kg P ha-1, second factor comprises seed inoculations with biofertilizer viz. alone inoculation of Rhizobium @ 6 ml kg-1 seeds, alone inoculation PSB @ 6 ml kg-1 seeds and dual inoculation Rhizobium + PSB each of @ 6 ml kg-1 seeds. The experimental site having gross and net plot size was 5.4 x 4.5 m2 and 4.2 x 3.9m2 respectively. The application of phosphorus @ 60 kg ha-1 given significantly higher growth and yield attributes, gross monetary return and net monetary return over the rest of the levels of phosphorus. Whereas NMR was remained at par with 50 kg P ha-1. Among three biofertilizer treatments, dual seed inoculation with Rhizobium + PSB was recorded higher growth and yield attributes, gross monetary return and net monetary return than the individual seed inoculation of Rhizobium or PSB.
