dc.description.abstractFourteen maize samples were analysed to investigate Lhe influence of variety and fertilizer treatment on the moisture, ash, lipid, mineral, carbohydrate and amino acid contents., Five varieties, namely TZB, 096, S 123, Bomo Local and western yellow were used for the influence of v trietal differences study while 9 groups of trv- variety used for the influence of fertilizer treatment study. The fertilizers were applied singly and in combination in the ".lowing doses: S.- (no fertilizer), S2 (25kg N/ha) , So (50kg N/ha), s4 (30kg P/ha), s5 (60kg P/ha), Sg 50kg K/ha), S7 (100kg K/ha), S« (25, 30 and 50kg N, P and K/ha respectively) and Sg (50, 60 and 100kg N, P and K/ha respectively). The samples used for the influence of varietal differences study, S1 Q (Bomo Local), sl a (S 123), S1 2 (096), S1 3 (TZB) and S14 (Western Yellow) all received combinations (120kg N/ha, 60kg P/ha, 60kg K/ha). Both fertilizer treatment and varietal differences had significant effects on the moisture and protein contents. Fertilizer treatment had significant effect on the ash and lipid contents while varietal differences had no significant effect on these. Analyses were done on the maize samples for the identification of 9 minerals namely, calcium, copper, iron, manganese, zinc, sodium, phosphorus, magnesium, and potassium. Fertilizer treatment and varietal differences had significant effects on the calcium, iron, manganese, sodium zinc and phosphorus contents. In addition, while fertilizer treatment had significant effects on the copper and potassium contents, varietal differences had none. Both factors had no significant effects on the magnesium content. The carbohydrates of the maize samples were characterised into their different fractions namely soluble carbohydrates, hemicelluloses, cellulose and lignin. Fertilzier treatment and varietal differences had significant effects on the soluble carbohydrate, hemicellulose and cellulose contents while only fertilizer treatment had significant effect on the lignin content. The soluble carbohydrates were further fractionated into fructosan, fructose, pentoses and "other sugars". Both fertilizer treatment and varietal differences had significant effects on the four fractions. All the maize samples had low lysine and high leucine contents. These gave leucine/lysine ratios greater than 4.6. Maize protein is therefore not nutritionally safe as a major source of protein. It is suggested that samp] S13 (TZB , 120, 60 and 60kg N, P and K/ha respectively) distributed to farmers for planting at the institute: for Agricultural Research, Samaru, Zaria. This suggestion is based on its leucine/lysine ratio.en_US
