Comparative effect of chemical fertilization and manure on the grain yield of hybrid maize in the forest zone of Nigeria

Abstract

Field trials were conducted at the International Institute of Tropical Agriculture, Ibadan, Nigeria (IITA) experimental field in 1985 and 1986 to compare the effect of chemical fertilization and organic manure on the grain yield of hybrid maize Variety: TZSRY. The result shows significantly lower grain yield from the untreated plots (the control, where no fertilization was carried out) than plots treated with manure together with inorganic fertilizer.
