Effect Type and Levels of Manure on Forage Production and Nutrient Quality of Sorghum (Sorghum bicolor (L.) Moench) Plant

Background and Objective: The high price of chemical fertilizers encourages the use of livestock manure as a replacement, the use of various types and dosage of cattle dung on sorghum plants will have an impact on the production and quality of forage, it was necessary in order to use it as ruminants feed. This study aims to determine the type and level of manure on the productivity and nutritional value of sorghum. Material and Methodology: The design used in this research was split plot design with the basic design of complete randomized design. The main plot: consisted of type of manure i.e. goats, cows, and chickens (K1, K2, and K3). Subplot consisted of dose use of manure (tones/ha): 0, 15, 20, and 25, each treatment was repeated three times. Each plot measuring 2 x 1.8 m2. Parameters measured include the production of fresh forage, nutrient content (protein,crude fiber, acid detergent fiber, netral detergent fiber). The data were analyzed by analysis of variance. Results: The results of analysis of variance showed that the type of manure was not significant (P> 0.05) to the production of fresh forage sorghum, but the level of manure doses significantly (P 0.05) to the proportion of sorghum stalks and leaves of plants. in the parameters nutrient content, the study showed significant effect on the water content and crude protein, while not significantly affect on crude fiber and netral detergent fiber content of sorghum. The highest yield in sorghum protein content (11.13%) contained in the fertilizer treatment cow manure at a dose of 25 tones/ha. Conclusion: The results showed that the highest production of sorghum forage and protein content was obtained at doses of fertilizer was 25 tons/ha.
