The following is based largely on the authors' summary of this further part. Field experiments in the Sudan Gezira in 1959-64 showed that when strains of Egyptian-type cotton resistant to blackarm were sown about the beginning of August and adequately protected from flea-beetles, the resultant crop was of higher yield and considerably better average quality than that from normal sowing in the latter half of August.
