Figure 2 - Fruit weight (kg) of hybrid papaya UENF / Caliman 01, grown under field conditions in water levels in the Catolé do Rocha microregion, Paraíba state, Brazil. Although the analysis of variance showed no significant effect on the number of fruits per plant and productivity, there were variations of these variables in different irrigation depths. The maximum amount of fruit occurred in the irrigation water depth corresponding to 75% of ETo, providing an increase of 5.5% related to the level 1 (50% of ETo) and 8.3% when related to Level 4 (125% of ETo). The maximum productivity (41.84 Mg ha -1 year -1 ) was found by applying 75% of ETo, decreasing from that point (5.7%). The lowest value (32.81 Mg ha -1 year -1 ) was obtained by applying 50% of ETo, indicating interference of moisture content on the available soil productivity. 4. Conclusions - The highest number of fruits per plant and maximum productivity is achieved in the rate of 75% of ETo. - The hybrid UENF/Caliman 01 can be cultivated in the semiarid region of Paraiba state with replacement rate of 75% ETo, without compromising the performance of crop yield.
