Abstract

A field experiment was conducted during summer and rainy seasons of 2007-08 at Sunnhemp Research Station, Pratapgarh, Uttar Pradesh to study the influence of organics in combination with inorganics on fibre productivity, nutrient uptake by sunnhemp (Crotalaria juncea L.), and residual effect on  rice (Oryza sativa L.) and soil fertility. Integration of Rhizobium, PSB and FYM with 50 and 75% NPK recorded equivalent fibre yield of sunnhemp (1.04 and 1.14 t/ha respectively), which were at par with 100% NPK (1.04 t/ha) and 100% NPK + FYM (1.12 t/ha). The highest grain yield of residual rice (4.45 t/ha) was recorded with 75% NPK + Rhizobium + PSB + FYM which was at par with 50% NPK + Rhizobium + PSB + FYM (4.30 t/ha) and 100% NPK + FYM (4.36 t/ha). The residual soil fertility improved considerably with the combined application of inorganic fertilizer and organics. It was concluded that integration of organics (Rhizobium, PSB & FYM) with inorganics led to 50% saving of inorganic fertilizer without scarifying the yield of sunnhemp-rice cropping sequence and improved soil fertility status.
