| 520 | |a The present study was conducted to generate new information about agronomic properties and nutritional quality of the five varieties of Napier grass. The specific objectives of this study was to identify the growth characteristics, measured dry matter yield, leaf to stern ratio and the nutritional quality of five different varieties of Napier grass. Five varieties of Napier grass were grown in a randomized complete block design with three replications to characterize and compare their production, agronomic properties and nutritional quality. The varieties of Napier grass which known by their common names were Silver Napier (SN), Dwarf Napier (DN), India Napier (IN), Purple Napier (PN) and Common Napier (CN). The Napier grass varieties was harvested three times with harvesting interval at five weeks each harvest. The growth characteristic measured were plant height, tiller number and leaf number per tiller and was collected on weekly basis. The dry matter yield and leaf to stem ratio was measured at every harvest. While, the chemical composition parameters measured were crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL) and ash. In terms of agronomic properties, there are significant differences (p<0.05) in height and tiller number of the varieties but no significant differences in leaf number per tiller among all varieties. For plant height, Dwarf Napier (DF) were significantly highest compared to others varieties. While for tiller number, Dwarf Napier (DF) were the highest average number of tillers (47.44) compared to other varieties. On the other hand, there was significance differences (p<0.05) in leaf to stem ratio among varieties with Dwarf Napier (DF) had the highest leaf to stem ratio compared to other varieties. The DM yield (DMY) among all varieties with Common Napier (CN) showed the significantly highest average DMY with 96.7 t/ha/yr, compared to other varieties. While for nutritive quality, there was a significances (p<0.05) in CP, NDF, ADF and ash between all varieties with on average DN varieties (CP content 14.82%) outperformed others. While for ADL content, there was no significance differences between all varieties (ADL<6.0%). In conclusion, these results showed that different Napier grass varieties have differences in production, agronomic properties and nutritional quality. DN shows better in nutritive quality (higher CP% content), higher tiller number and stem to leaf ratio compared to other varieties. CN showed higher DM yields compared to others in term of DM production. (KEYWORDS: Napier grass, Morphological differences, Nutritive Quality) | ||
