REUSE OF WASTEWATER FROM MILKING IN CACTUS PEAR UNDER DIFFERENT IRRIGATION AND FERTILIZATION FREQUENCIES
The aim of this study was to evaluate the performance of cactus pear cv. ‘Miúda’ (Nopalea cochenillifera Salm Dyck) in dense cultivation under different fertilization and irrigation frequencies with reuse water in the semiarid region of Sergipe.

| Sumario: | The aim of this study was to evaluate the performance of cactus pear cv. ‘Miúda’ (Nopalea cochenillifera Salm Dyck) in dense cultivation under different fertilization and irrigation frequencies with reuse water in the semiarid region of Sergipe. The design was in split plots, with three replicates of four irrigation plots (7, 14, 21 and 28) and one control (no irrigation) and four fertilizations: organic fertilization levels 1 (35t bovine manure ha-1), organic fertilization 2 (35t sheep manure ha-1), chemical fertilization (150 kg N ha-1) and fertigation (wastewater). Growth variables (Height, TCV-Vertical Growth Rate; TCH-Horizontal Growth Rate; TApC- Cladode Appearance Rate) showed no differences in relation to irrigation frequency with control; NCT- Total Cladode Number, CC- Cladode Length, EC- Cladode Thickness, VT- Total Volume and EUA- Water Use Efficiency, were similar among treatments and LC-Cladode width was inversely proportional; irrigation frequencies of 7 and 14 days were similar and greater than 21 and 28 days. In the control treatment (rainfed), yield was 23.84 t DM ha-1, the lowest obtained when compared to the highest yield of the 14-day irrigation frequency, which was 30.11 t DM ha-1. Irrigation frequency of 7 days promoted better morphological results in cactus pear. It could be inferred that, at 18 months of age, if the water factor is not limiting, cactus pear cv. ‘Miúda’ can reach its maximum growth point, which is when the 5th order of appearance of cladodes is reached. |
