Response of Rainfed Cassava to Methods of Application of Fertilizer-Nitrogen in a Coastal Savannah Environment of Ghana

Abstract

A study was carried out during the 2004/2005 and 2005/2006 cropping seasons to evaluate the response of two cassava genotypes Afisiafi and Akwetey to methods of application of fertilizer-nitrogen. The objective was to quantify, in relation to three methods of application of fertilizer-nitrogen, total dry matter, fresh root yield, accumulated nitrogen and apparent recovery of fertilizer-nitrogen by the cassava genotypes, Afisiafi and Akwetey, grown under rainfed condition in the coastal savannah environment of Ghana. The two cassava genotypes were grown on the field under rainfed condition and 60 kg N ha was split-applied using 1
