Title: Effect of Nitrogen and Phosphor-as Fertilizers on Growth and Yield of Some Gramin,%ceous Forages
Author: Abusuwar, Awad
Abstract: An experiment was conducted for two consecutive seasons (1987/88 and 1988/89) at the Demonstration Farm of the University of Khartoum in Shambat to test the response of some graminaceous forages to nitrogen and phosphorus fertilizers and to examine the residual effects of these fertilizers on ratoon yield. The tested crops were Abu Sabein (SLYghum bicolor (L.) Moench), sudangrass (Sorghum sudanense), Pioneer 988 (Sorghum bicolor x Sorghum sudanense), and napiergrass (Pennisetum purpureum). Four levels of fertilizer combinations of urea and superphosphate, namely ONOP (control), ON2P, 2NOP and 2N2P were used and arranged in a randomized complete block design with three replicates. Nitrogen fertilizer significantly improved growth and productivity of the graminaceous forages, whereas phosphorus had no effect on growth attributes but it significantly improved the productivity in the second season. Among the graminaceous forages, napiergrass outyielded the others due to its high tillering capacity.
