Abstract: A field experiment was conducted from winter season 1997-98 to rainy season 1999 at Fatehpur-Shekhawati (Sikar), Rajasthan, to study the effect of residual phosphorus, sulphur and biofertilizers on productivity, economicsand nutrient content of pearl millet [Pennisetum glaucum (L.) R. Br. Emend Stuntz] in fenugreek (Trigonella foenum-graecum L.)-pearl millet cropping sequence. Increased application of P up to 35.0 kg/ha, increased the grain yield of fenugreek by 23.1 and 6.7% compared with the control and 17.5 kg P/ha respectively. Application of P (35.0 kg P/ha) in fenugreek increased the grain and stover yield of succeeding pearl millet by 33.3 and 39.0% over the control, respectively, and N and P content of pearl millet grain (7.1 and 59.1%) and stover (29.2 and 20.0%) over the control. However, this treatment could not significantly affect the S content. Residual sulphur (100 kg S/ha) significantly increased the grain (12.5%) and stover (10.6%) yield of pearl millet compared with the control. This treatment also significantly increased the sulphur content in pearl millet grain (13.3%) and stover (11.1%) over the control. Fenugreek seed inoculation with Rhizobium + phosphate-solubilizing bacteria increased the seed yield of fenugreek by 3.4% and stover yield of succeeding pearl millet by 3.9% over no-seed inoculation. Seed inoculation with Rhizobium and Rhizobium + phosphate-solubilizing bacteria significantly increased the N content of soil after harvest of fenugreek by 3.5 and 4.8% and after harvest of succeeding pearl millet by 0.3 and 4.1% compared with no-seed inoculation.
