Performance Evaluation of Napier Grass (Penisetum Purpuruem (L.) Schumach) accessions under rain fed and Irrigation System at Wondo Genet

Aman Getiso* and Diribi Mijena

Six Napier grass accessions (Penisetum purpuruem) that have been tested and identified for their better agronomic and yield performance at different national and regional research centers were collected and tested at Wondo genet Agricultural Research center under two sets (under irrigation and rain fed) conditions. The experiment was conducted in randomized complete block design with three replications. Under supplementary irrigation there was no significant difference (P>0.05) of mean yield and yield components observed among accessions both under fertilizer application and without fertilizer application with fresh biomass yield (t/ha) ranged from 43.73 to 70.24 and that of dry biomass yield (t/ha) ranged 11.54 to 20.32. Under rainfed condition the combined mean analysis for tiller number per plant, plant height, node number per plant and internodes length per plant did show significant (P<0.05) while fresh biomass yield and dry matter yield didn’t show significant (P>0.05) difference. Fresh biomass yield (59.11 t/ha) and dry matter yield (16.17 t/ha) for fertilizer application is significantly higher (p<0.05) than fresh biomass and dry matter yield of 40.51 t/ha and 10.51 t/ha respectively for non-fertilizer applied Napier accessions under rain fed condition. Both under supplementary irrigation and rainfed conditions, Napier accessions 14983, 15743 and 16788 responds better mean fresh and dry biomass yield. Hence, among tested genotypes 14983, 15743 and 16788 Napier grass accessions will be encouraged in the study area and similar environment.
