Experiment was conducted with the aim of comparing the effect of various farm manure sources on yield and nutritive values of Pearl Millet according to Randomized Complete Block Design (RCBD). There were 5 treatments; farm manure 1.5 ton/rai combined with chemical fertilizer (grade 15-15-15) 15 kg/rai (T1), poultry manure (T2), swine manure (T3), cattle manure (T4), mixed farm manure (T5) at the rate of 3 tons/rai for T2, T3, T4, and T5. Four times of harvesting was employed. It was found that at the first cut of Pearl Millet, T2 showed similar yield to T1, T3 and T5 but significantly higher than T4 (P0.05). Total yield of grass in T2 tended to be greater than T1, T5, T3 and T4 respectively. Stem sweetness of grass (using digital refractometer) in T2 showed significantly higher than T1, T3, T4 and T5 (P0.05) at the first cut. Averaging data from the 4 harvesting, it was observed that Pearl Millet growing by T2 tended to be more accumulated sugar in stem as compared with other treatments. It was also observed that crude protein and NDF contents with T2 seemed to be superior than T1, T3, T4 and T5 but no statistical significance whereas ADF of Pearl Millet tended to be less accumulated in stem as compared with other treatments. The results indicated that poultry manure was more effective utilization for Pearl Mellet growing than swine and cattle manure it can be given a better yield and better nutritive composition for ruminants than the use of swine and cattle manure.
