Effect of cutting interval on dry matter production and nutritive value of three varieties of Napier (Pennisetum purpureum) grass /
Forages plots were established to evaluate the effect of cutting interval and forage varieties on the quality and productivity of napier grass. The varieties were Pennisetum purpureum cv Princess, Pennisetum purpureum cv Bajra and Pennisetum purpureum cv Taiwan. Grasses were sampled at 35 days and 4...

| Summary: | Forages plots were established to evaluate the effect of cutting interval and forage varieties on the quality and productivity of napier grass. The varieties were Pennisetum purpureum cv Princess, Pennisetum purpureum cv Bajra and Pennisetum purpureum cv Taiwan. Grasses were sampled at 35 days and 42 days and then analyzed for ash, crude protein (CP), crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE), nitrogen free extract (NFE), total digestible nutrient (TDN), calcium (Ca) and Phosphorus (P). Significant differences (P<0.05) in height of plant, crude protein (CP) and neutral detergent fiber (NDF) and nitrogen free extract (NFE) were observed among the napier varieties where Pennisetum purpureum cv Bajra and Pennisetum purpureum cv Taiwan were significantly higher than Pennisetum purpureum cv Princess. Significant differences (P<0.05) in height of plant, dry matter production, ash, crude protein, crude fiber and acid detergent fiber were observed at different cutting interval. The dry matter production, height of plant, ash and crude fiber percentage were superior at the 42-days cutting interval compared to the 35-days cutting interval. However, result of the study showed that there was a reduction of crude protein when the cutting interval increased. No significant different (P>0.05) observed in leaf percentage, EE, NDF, NFE, TDN, Ca and P at different cutting interval. There were significant different (P<0.05) crude protein between varieties and cutting interval. No interactions (P>0.05) were observed among varieties and between cutting interval. |
