Data on growth were collected through systematic sampling up to 74 days. The adjusted growth curves, as an exponenetial and linear model, showed that total leaf P, K, Ca and Mg followed the ratio of 1:14:8:2. The Ca:Mg ratio was 4:1. The maximum absorption (mg/pot) for Zn (2.52), Cu (0,38), Fe (5,54), and Mn (0,65) was at 62,54, 60 and 54 days, respectively. The first approach for plant diagnosis could be K=2% (51 cmol/kg); P = 0,15% (4,8 cmol/kg); Mg = 0,29% (24 cmol/kg), and Ca =1% (50 cmol/kg). The Ca + Mg/K ratio was 1.5.  aArachis pintoi  aLeguminosa forrageira  aMineral nutrition  aNutricao mineral1 aPURCINO, H.1 aVIANNA, M. C. M.1 aFRANCA, C. C.
