Résumé:
The objective of this work was to evaluate the effect of irrigation levels and potassium
rates applied through irrigation water by drip irrigation on the yellow passion fruit yield. The
experiment was accomplished in the Experimental Field at Embrapa Meio-Norte, in Alvorada of
Gurguéia – PI, Brazil. It was used experimental design of randomized block in plot subdivided with
four replications. The treatments resulted from the combination among five irrigation levels (L1 = 0.25
EVA; L2 = 0.50 EVA; L3 = 0.75 EVA; L4 = 1.00 EVA and L4 = 1.25 EVA) in that, EVA is the Pan
Class A evaporation and five potassium rates (K0 = 0.00, K1 = 0.225, K2 = 0.450, K3 = 0.675 e K4 =
0.90 kg plant-1 year-1). The passion fruit commercial yield was influenced (P<0.01) by potassium rates,
irrigation levels and by interaction of those factories. Lower irrigation levels showed linear increase of
the yield with the elevation of potassium rates. On the other hand, for highers irrigation levels, the
obtention of values maximum required application of higher potassium rates
