The objective of this study is to determine the effects of the different harvesting ages (45 days, 60 days and 75 days) on the chemical composition of five Napier grass varieties. This research was conducted at Universiti Sultan Zainal Abidin (UniSZA) Farm in Pasir Akar, Besut, Terengganu. The proximate analysis was used to analyze the chemical compositions of moisture, ash, crude fiber, crude protein and fat, while the mineral compositions of magnesium, potassium, aluminium, phosphorus, and calcium were analyzed and measured using the dry ashing method and Induced Couple Plasma Optical Emission Spectrometry (ICP-OES). The findings of this study showed that most chemical compositions of five Napier varieties were decreased (p < 0.05) as harvesting age increased. The proximate composi-tions of all varieties show significantly decreased (p < 0.05) as age increased which is the moisture, ash, crude fiber, crude protein, and fat were decreased at age 75 days. Among the five varieties, Dwarf Napier shows the highest of crude protein (25.51%) followed by In-dia Napier (22.44%), Uganda Napier (18.45%), Red Napier (18.26%) and Zanzibar Napier (16.78%), respectively.
