Abstract
Field trials were conducted in 2004-2007 wet and dry seasons at the National Cereals Research Insti E, 70.5 metres above sea level) in the Southern Guinea Savannah ecological zone of Nigeria to study the effect of fertility rates on weed and yield of chewing sugarcane. Randomized complete block design was adopted for the study in which seven fertility rates evaluated were -: F0 = Control (no cattle manure no inorganic fertilizer), F1 = 120kgN/ha 26kgP/ha 37kgK/ha (NCRI recommended rate for sole chewing sugarcane), F2 = 10 t/ha of cattle manure alone (NCRI recommended rate for sole chewing sugarcane), F3 = 10 t/ha of cattle manure + 120kgN/ha 26kgP/ha 37kgK/ha, F4 = 10 t/ha of cattle manure + 60kgN/ha 13kgP/ha 18.7kgK/ha, F5 = 5 t/ha of cattle manure +120kgN/ha 26kgP/ha 37kgK/ha and F6 = 5 t/ha of cattle manure + 60kgN/ha 13kgP/ha 18.7kgK/ha The results showed that the combined cattle manure10 t/ha + 120kgN/ha 26kgP/ha 37kgK/ha, 10 t/ha of cattle manure + 60kgN/ha 13kgP/ha 18.7kgK/ha, 5 t/ha of cattle manure + 120kgN/ha 26kgP/ha 37kgK/ha and 5 t/ha of cattle manure + 60kgN/ha 13kgP/ha 18.7kgK/ha consistently resulted significantly in better weed performance , stalk girth and stalk yield than the separate application of cattle manure at 10 t/ha and 120kgN/ha 26kgP/ha 37kgK/ha. Among the combined rates, the effect of lowest combined rate of 5 t/ha of cattle manure + 60kgN/ha 13kgP/ha 18.7kgK/ha on stalk girth and stalk yield was significantly similar compared with higher combined rates but volume of weed obtained from the lowest combined fertilizer was significantly lower than the remaining combined rates.
