Field experiments were conducted during 2014-15, 2015-16 and 2016-17 at Zonal Agricultural and Horticultural Research Station, Babbur farm, Hiriyur, Karnataka, India to study the efficiency of bio-phos and phosphate solubilizing bacteria on castor yield at different levels of phosphorus fertilizer under rainfed conditions. The experiment was laid out in randomized block design with three replication and nine treatments. Three years pooled results indicated that there was a linear response of seed yield (1620 kg/ha) and higher economics like gross return (Rs. 54320/ha), net return (Rs. 35135/ha) and B:C ratio (2.6) due to application of 40 kg P2O5/ha + PSB 20g/kg castor seed has compared to control and seed treatment with biophos alone, respectively. Further in the farmer’s field yield of Rangappa s/o Badagi (1627 kg/ha), Palanna s/o Kamaiah (1748 kg/ha) and Prahalada s/o Obalajja (1695 kg/ha) was recorded in the improved practice treatment as compared to farmer practice. The average yield of three demos was (1690 kg/ha), gross return (Rs. 60840), net return (Rs. 36259) and B:C ratio (2.46) showed highest in the improved practice as compared to farmer practice.
