Abstract

An experiment was conducted to evaluate the effects of different levels of N on forage yield and silage quality of three sorghum cultivars. The sorghum cultivars Viz: Speed feed, Jumbo, and Syahzan, a native strain, were cultivated in four levels of N fertilizer (0, 50, 75, and 100 Kg/ha). Their yield and quality were compared in a Completely randomized block design with split - polt layout and three replications. Seeds were hand sown in a density of 20 plant/m2 in late spring 1997. The CP, CF, Ash and pH content of the harvested plants were measured by the appropriate procedures. Laboratory silages were made from the harvested and chopped plants with DM content of 18.9 to 22.2 in a polyethylene 20 liters containers for 6 weeks in ambient temperature. Nitrogen application of 100 Kg/ha produced the highest forage dry matter as well as silage production in Syahzan cultivar. Jumbo cultivar significantly produced the highest forage and silage dry matter than the other cultivars (14 and 13.5 tons DM/ha), respectively. There was a significant difference (p<0.05) among cultivars for protein component, crude fiber percentage and ash content. The native strain (Syahzan) and Speed feed produced highest protein percentages and protein yield as well as the highest crude fiber, respectively. Ensilage caused an increase in protein, crud fiber and ash content for all cultivars.
