Abstract: A field experiment was conducted during winter season of 2003-04 to study the effect of enrich, an organic source of plant nutrients on the production of rapeseed in the incsptiso/s of West Bengal. Highest seed yield of 1528 kg/ ha was obtained when full doses of NPK (80:40:40 kg ha\\\"1 N:P20 5:K20 respectively) were applied along with the Enrich 1500 kg/ha followed by full NPK Enrich 1250 kg/ha (1367 kg/ha) and both showed significantly higher rapeseed yield as compared with the full doses of only NPK (1033 kg/ha). Plant h~i~ht, branches I plant and siliqua I plant showed similar tfend of variations as recorded in case of se~ yield. The chemical analysis of available nitrogen, total phosphorus and total potash In the soil taken at initial stage and after harvesting clearly indicates the benefits of using Enrich with NPK over sole application of NPK. Population on non-symbiotic nitrogen frxing bacteria and PhospHorus solubilizing bacteria in the rhizosphere soil of rapeseed also increased due to the application of Enrich. Key words: Enrich, production, rapeseed.
