The study was conducted in Jinka agricultural research center south agriculutural research institute Southern Ethiopia with objective of identifying effect of planting space and fertilizer rate on productivity of desho grass. Planting of Desho grass has been conducted in four planting space (level1= 0.25cm between plants and 0.5cm between rows, levele2= 0.5cm b/n plants and 0.75 b/n rows, level 3= 0.75cm b/n plants and 1meter b/n rows, level 4= 1 meter b/n plants and 1.25 meter b/n rows) and five fertilizer rates (control, 0.5 DAP and 0.5ql urea, 1 ql DAP and 1.5 ql urea, 1 ql DAP and 2 ql urea, 1.5 ql DAP and 2 ql urea ). The experiment has used a plot size of 3m x 4m. Field trial was arranged in a randomized complete block design (RCBD) with three replications. Plant height, number of tiller per plant and dry matter yield were recorded. The results indicated that planting space evaluated showed statistical significant variation (p<0.05) in dry matter yield (t/ha-1) and number of tillers while there is no statistically significant difference in plant height at harvest (m). It is recommendable that utilization of fertilizer at treatment level 2 is important for farmer whereas it is better to apply treatment level 4 for youth/ non-employed group and investors who are participated in forage seed production. Cost benefit analysis has to be conducted through hay making or animal response.
