A field experiment was conducted in Old Brahmaputra Floodplain soils (Sonatala series) of BJRI Farm, Kishoreganj to study the effect of phosphorus and sulphur in presence and absence of Urea-N and Rhizobium inoculation on peanut (Arachis hypogaea L.). The experiment was laid out in split plot design with 27 fertilizer treatment combinations, replicated thrice. Results indicated significant favourable effect of nitrogen treatments and sulphur on number and weight of pods per plant and pod yield. Application of P showed significant favourable effect only on pod number and pod yield. The interaction of P and S and of N, P and S has significant effect on number of pods per plant. Besides, there was significant positive correlation of weight of nodules, and number and weight of pods with pod yield indicating favourable influence of these plant characters on pod yield. Use of Rhizobium inoculant and application of 30 kg urea-N gave an increase in pod yield by 20% and 22% respectively over N control plots. Application of 20 kg and 40 kg S/ha increased pod yield by 11% and 13% respectively over So plots but the effect of P was not spectacular. The combination of urea-N (30 kg N/ha) and sulphur (40 kg S.ha) and that of Rhizobium inoculation and sulphur (20 kg S/ha) with 30 kg P/ha recorded the pod yield of 2.68 tons/ha (61% increase over control) and 2.53 tons/ha (52% increase over control), respectively.
