In order to know the effect of PSB seed treatment and P levels on P-fractions in different growth stages of groundnut a field experiment was conducted on a sandy loam soil at KVK, UAHS, Shimoga during kharif of 2013 The levels of phosphorus @ 0, 25, 37.5 and 50 kg P2O5 as DAP per ha-1 with or without PSB seed treatment were tried in a randomized complete block design with three replications and eight treatments. The result indicated in all the growth stages higher values of saloid – P and Ca – P fractions status in soil were recorded in treatment 50 kg P2O5 ha-1 as DAP with PSB seed treatment at similarly higher values of Al - P, Fe – P, red – P, occl – P, organic – P and total - P fractions were recorded in treatments involving P levels without PSB seed treatment compared to application of P levels with PSB seed treatment. The treatment which receives 50 kg P2O5 ha-1 as DAP recorded higher Al-P, Fe – P, red – P, occl – P, organic – P and total - P values in all the growth stages of groundnut.
