Agriculture dominates the Ethiopian economy. It is the major supplier of raw materials to foodrnprocessing, beverage and textile industries. Application of fertilizer is one of the majorrninterventions made by the government to increase the productivity of the sector. The governmentrnfocuses on productivity improvement of smallholder agriculture through diffusion of fertilizersrnand improved seeds. However, the price of chemical fertilizer is increasing from time to timernwhich results in shortage of the supply and unaffordable to smallholder farmers. rnThe objective of the study was to (i) to see the effect of bioslurry from coffee husk on the macrornnutrients of the soil (ii) to assess the influence of bioslurry from coffee husk on soil organicrncarbon content (iii) to compare the effect of bio slurry on yield and yield components of the testrncrop (iv) To compare the economic benefit of bio slurry application from yield perspective.rnIn order to achieve the stated objectives, a pot study was conducted under greenhouse condition.rnSeven treatments were designed with combined and sole application rates of bioslurry and urearnto 5 kg soil potrn-1rnusing wheat as a test crop. rnThe results of the study revealed that combined and sole application of the bioslurry withrnchemical fertilizer positively increased the yield, yield component of the test crop and organicrncarbon soil. The conjugate application of bioslurry with chemical fertilizer at (3.1mrnbioslurryrn+62 kg urea) harn-1rngave the highest yield (4368.2 kgharn-1rn) and highest spike length was alsornrecorded with this treatment. The high application rate of bioslurry at (6.2mrn3rn) increased thernsoil organic carbon content over 100% compared to the control without any amendment. Thernsimple economic calculation based on economic efficiency indicated that the combinedrnapplication of bioslurry with chemical fertilizer at (3.1 mrn3rn+62 kg urea) ha-rn1rngave a net benefitrnof 23, 460.8 ETB.rnThe study showed that the appropriate utilization of bioslurry as soil amendment not onlyrnincreases soil fertility but also plays a great role in alleviation of climate change throughrnincrement of soil organic carbon which in turn serves as a carbon pool of planet earth.
