dc.description.abstractField trials were conducted at Samaru over a period of two years 1991/93 to study the differential susceptibility of three maize cultivars (Ag-Kaduna, mega hybrid and T2BSR-Y) to zinc deficiency. The zinc application rates were 0, 1.0, 2-5, 5-0 and 7-5kg Znha-1. There were response in cob length diameter, 1,000 grain weight and grain yield of maize with increase in zinc rates- A zinc rate of l-0kg Znha-1 appeared to be good for optimum yield of maize- Ag-Kaduna appears to be less susceptible to zinc deficiency than the other two varieties- When the nutrient concentrations were compared with zinc rates there appeared a markedly decrease in the concentration of Iron (Fe) and Phosphorus (P) as zinc rate increased- This shows that the absorption of Fe and P in the varieties appear to be the cause of differential susceptibility to zinc deficiency.en_US
