Five (5) experiments, located in the peanut region of the State of São Paulo, Brazil, were installed in big plots, with the aim of studing the effect of lime applied at planting time on two peanut cultivars. Liming at planting time at the rate of 1,230 kg/ha of lime increased yield of the cultivar Tatu (Valencia vegetative type) in one of the experiments. The Tatuí cultivar (spanish vegetative type) gave on response to liming.
