Abstract

In semiarid regions the irrigation is essential for obtaining high yields and fruit quality of pineapple. 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 vegetative growth, flowering, production and fruit quality and slips production were evaluated. The plants of pineapple that have received regarding the irrigation at 30, 50, 70, 100 and 150% of PAN do not differ for the characteristics of productivity, fruit weight with and without crown diameter and fruit length, skin color, total soluble 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 productivity is greater in depth corresponding to 85% of PAN.
