The field experiments were conducted at the Main Oilseeds Research Station, Junagadh Agricultural University, Junagadh to assess the response of bio- phos (Chaetomium globosum) on castor and compared its efficiency with applied inorganic phosphorus through fertilizer during kharif season of year 2011-12 to 2013-14 on medium clay soil under irrigated conditions. The experiment consisted of eight treatment combinations of seed treatment with bio-phos @ 30g inoculants/50 g. castor seed (cv. GCH 7) seed with different doses of phosphorus (20 kg, 40 kg and 60 kg/ha). The seed yield of castor was increased due to seed inoculation with bio-phos to the tune of 309 kg/ha, 33 kg/ha, 188 kg/ha and 156 kg/ha over sole application of 0, 20, 40 and 60 kg P2O5 /ha, respectively. The increment in seed yield of castor with bio-phos was higher at 40 kg/ha applied P and decreased with addition of inorganic P. Castor seed yield improvement of 8.35%, net returns of Rs 36989/- and B:C ratio of 2.64 were recorded under application of 40 Kg P2O5 /ha along with seed inoculation of bio-phos.
