N2  - Low crop production in the southern region of Ethiopia is due to decline in soil fertility. Organic fertilizers such as coffee husk/pulp (CHP) can be an alternative to chemical fertilizer whose price has recently increased. Evaluation of the residual effect of CHP was conducted for three consecutive seasons. Split plot in RCBD with three replications was used. The main- and sub-plot treatments were two levels of nitrogen fertilizer (O and 46 kg N/ha) and nine rates of CHP (O to 20 t/ha with an interval of 2.5 t/ha), respectively. Application of CHP has under unfertilized condition increased the mean yield over seasons. The increment was more than 5% over the check. On the other hand, in fertilized situation, relatively higher mean yield (5.5% more) was achieved from CHP when compared to yields from N-fertilized alone. It is found that CHP serves as a means to conserve moisture at times of moisture stress. In addition, application of CHP has resulted in grain yield increases of more than 230 kg/ha under both conditions. The result also indicated the carry-over effect of the pulp. In summary, a farmer who grows coffee can use the by-product as source of organic fertilizer to increase crop yield per unit area
