N2  - To find out the effect of enriched farm yard manure (FYM) on grain yield of maize, an experiment was conducted on farmers' fields around Bako during 2000 and 2001 cropping seasons. The experiment "as laid out in a randomized complete block design (RCBD) with two replications. Enrichment of conventional FYM was done separately with 25% and 50% each of recommended nitrogen (N) and phosphorus (P) fertilizers and their combinations from urea and diammonium phosphate sources. Enrichment of conventional FYM improved the quality of FYM. Total N and P was increased from 1.8% and 0.35 ppm in conventional FYM to 2.43% and 1.05 ppm in enriched FYM, respectively. The growth and yield of maize were increased significantly ,with the application of enriched FYM. Enriched FYM increased grain yield by 40% compared to conventional FYM. However, the residual effect of enriched FYM was very marginal. Application of 25% NP enriched FYM gave the highest marginal rate of return of 296%. This remained robust when maize price decreased by 20% and fertilizer Cost increased by 10%. It was concluded that application of enriched FYM is superior to conventional FYM and on par with recommended mineral fertilizers on maize grain yield. By following enrichment technology 75% of mineral fertilizers cal1 be saved for maize production in Bako area
