With a view to compare the effects on fruit bearing, pruning of fig trees was carried out in Campinas, State of São Paulo, during the dormant season of the plant, at 5 different dates, namely on the 1st day of each of the months of May, June, July, August and September. Pruning was started as soon as the plants became more or less dormant in the fall and was continued until vegetation again appeared at the end of winter. The pruning operation took place for two following years and at the dates mentioned all the new branches were cut back to short stubs. The experimental plot consisted of 30 trees of the variety "Roxo de Valinhos" (San Piero) spread apart 7 by 13 feet and was laid out in randomized blocks with 3 replications. The results of this trial can be summarized as follows: a) Trees pruned on August 1st gave the highest yield followed by those pruned on July 1st. While the difference between these two results was not statistically significant both yields were, however, significantly better than those obtained from trees pruned in the three other months. b) There was observed a tendency for heavier ripe figs and earlier ripening of the crop, which was exactly due to the pruning at the proper time.
