Description A field experiment with sunnhemp (Crotalaria juncea L.)-wheat (Triticum aestivum L.emend Fiori & Paol.) cropping system was conducted during 2004 and 2005 to study the effect of phosphorous and farmyard manure levels on yield and nutrient uptake of sunnhemp and their residual effect on wheatand changes in soil fertility status. Application of farmyard manure @ 5 tonnes/ha recorded an increase of 13.9% in fibre yield over the no farmyard manure. Fertilizer phosphorus significantly increased the fibre yield of sunnhemp of 14.69% over the no phosphorous at 40 kg p2o5/ha. The highest fibre yield (0.90 tonnes/ha) was recorded with combined application of 60 kg p2o5 and 7.5 tonnes farmyard manure/ha which was 45.2% higher than the yield of without phosphorous and farmyard manure. thThe total nitrogen, phosphorousand potassium uptake by sunnhemp increased significantly with applied phosphorous up to the maximum level of 60 kg p2o5/ha but the favorable effect with farmyard manure was recorded up to 5 tonnes/ha only. The increase in nitrogen, phosphorous and pottasium uptake with 60 kg p2o5/ha were 20.5, 44.0, 54.9% respectively over no phosphorous. Grain and straw yield of wheat straw increased significantly with farmyard manure at 5 and 7.5 tonnes/ha applied in sunnhemp over no farmyard manure although the yield recorded with 5 and 7.5 tonnes farmyard manure/ha were at par.The increase in grain and straw yield under 5 tonnes farmyard manure/ha was 6.60 and 14.05% respectively. Combined dose of 60 kg p2o5 with 7.5 tonnes farmyard manure/ha applied in sunnhemp recorded highest grain yield of wheat(4.55 tonnes/ha) which was 21.3% higher than that of without phosphorous and farmyard manure. The nitrogen, phosphorous and potassium uptake by wheat crop increased significantly due to the residual effect of farmyard manure and phosphorous applied in sunnhemp crop. Application of phosphorous and farmyard manure had significantly improved the organic carbon and available nitrogen, phosphorous and pottasium status in post-harvest soil after 2 years of cropping.
