The concentration of the harvest in a period of the year is a great economical problem for growers because of the fall of prices when the offer increases. Winter harvest attains the best prices of the year, but they occur when the trees produce few fruits. With the aim of getting out-of-harvest season, several treatments were applied, including those involving branch pruning and application of urea to the foliage, in two orchards in Veracruz, México, one in Cuitlahuac and another in Tlalixcoyan, during November and December, respectively. In Cuitlahuac, branch pruning and foliar application of urea 5 % got 31.5 flowers per square meter, versus 7.6 % of the control, but the number of fruits was similar to the control, as well as fruit weight and total weight of fruits per tree. In Tlalixcoyan, pruning and foliar urea 10 % (T1) showed better results on blooming (118.75 flowers per square meter) than the control (6.5); greater (20.2) number of fruits per square meter than the control (2.33), and the highest values for harvestable fruits.
