Abstract
ABSTRACT The effects of three levels of manure application (0, 4 and 8 ton/10 a) with basic fertilizer (N : P : K = 10:10:10 kg/10 a) on the yield and chemical composition of maize (Pioneer 32K61) and sorghum (FS501) forages were examined in 2 successive years, 2001–2002. Maize was harvested at yellow ripe stage, while sorghum at dough stage. Dry matter yield (DMY) of sorghum was significantly higher than that of maize in both 2001 and 2002. Although, DMY of both sorghum and maize were not significantly affected by manure levels in 2001, they increased with the level of manure in 2002. Maize had higher levels of crude protein (CP) and lower crude fiber concentration than those of sorghum in both 2001 and 2002. Manure application had no effect on chemical compositions of both maize and sorghum except for CP in both years and organic a fraction (Oa) concentration in 2002. The higher manure application might have greater effects on sorghum and maize production because of higher DMY in the second year without any increase in fiber fraction.
