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.Collection: CIMMYT Publications Collection
