CRESCIMENTO, PRODUÇÃO E QUALIDADE DO ABACAXIZEIRO ‘PÉROLA’ SOB DIFERENTES LÂMINAS DE IRRIGAÇÃO

In semiarid regions the irrigation is essential for obtaining high yields and fruit quality of pine- apple. The objective of this work was to evaluate the vegetative characteristics, fruit and slips production and fruit quality of pineapple, under different drip irrigation depth. The experiment was conducted in a randomized block design with five treatments replacement of class A evaporation pan (PAN), with 4 replications. The vege- tative growth, flowering, production and fruit quality and slips production were evaluated. The plants of pine- apple that have received regarding the irrigation at 30, 50, 70, 100 and 150% of PAN do not differ for the char- acteristics of productivity, fruit weight with and without crown diameter and fruit length, skin color, total solu- ble solids (TSS), total titratable acidity (TTA), TSS / TTA and pH of the pulp. The pineapple 'Perola' has greater vegetative growth in irrigation depth applied between 67,1 and 79,1% of PAN. The natural flowering cumulative total is greater in depth corresponding to 70% of PAN. The slips production per plant and slips pro- ductivity is greater in depth corresponding to 85% of PAN.
