Nursery experiment was conducted at Haru Agricultural Research Sub center of Jimma Agricultural Research Center, Western Ethiopia, to investigate biomass production and partitioning of Arabica coffee seedlings under different lime and coffee husk compost rates and establish optimum combination of these agricultural inputs that produce seedlings with better biomass production for field planting. The experiment was laid out in a factorial experiment arranged in randomized complete block design with three replications. The treatments included four levels of lime (0, 1.6, 3.2 and 4.8 t ha^-1) and coffee husk compost (0, 5, 10 and 15 t ha^-1). Biomass production and partitioning data of coffee seedlings were collected and subjected to analysis of variance using SAS package and treatment means were compared at 0.05 probability using least significance difference. The results revealed that lime and coffee husk compost rates significantly (P< 0.01) affected biomass production and partitioning of coffee seedlings. The highest biomass production of coffee seedling were obtained from the application of 15 t ha^-1 coffee husk compost and combined use of lime and coffee husk compost at the modest levels of 3.2 t ha^-1 lime and 10 t ha^-1 coffee husk compost with a nonsignificant variation. From the study, it can be concluded that application of 15 t ha^-1 coffee husk compost or combining 10 t ha^-1 of coffee husk compost and 3.2 t ha^-1 of agricultural lime could be a promising alternative amendment for acid soil management and production of vigorous coffee seedlings with high biomass production in Haru areas. But, further investigations should be continued under field conditions across locations and seasons to evaluate the effects of liming and coffee husk composts in ameliorating soil acidity, and improving growth, yield, nutrient uptake and quality of coffee varieties and establish their profitable levels for sustainable soil fertility management and production of Wollega coffee in western Ethiopia.
