Analysis of a number of groundnut cultivars for several years showed variation in Zn concentration in seed with year, field and crop responsiveness to Zn fertilizers. Its concentration ranged from 21 to 67 mg/kg with a mean value of 42 mg/kg and with application of 1-2 kg Zn, increased to 24-78 mg/kg with a mean of 49 mg/kg. Twenty high Zn density groundnut cultivars with more than 50 mg/kg were identified for use as food.
