Ten (10) experiments, located in the peanut region of the State of São Paulo, Brazil, were installed in big plots, with the objective of studying the effect of lime applied prior to planting on two peanut cultivars. Liming before planting at the rate of 1,230 kg/ha of lime increased yield of the cultivar Tatu (valencia vegetative type) in two of the ten experiments. The Tatuí cultivar (spanish vegetative type) gave no response to liming. There were differences neither among the seed/husk ratio in the treatments, nor among the experiment sites.
