Foliar potassium fertilization of passion fruit (Passiflora edulis) in the production stage.

Abstract

The objective of this research was to determine the effect of foliar potassium fertilization on the passion fruit (Passiflora edulis) crop at the Mishilí-Santo Domingo de los Tsáchila farm: T1(1 cc), T2 (3 cc), T3(5 cc), T4 (7 cc) and T5 (9 cc), implemented in a Block Design Completely Randomized (DBCA), with two replications. The variables evaluated were: leaf area (cm2), fruit number, fruit diameter (mm), fruit weight (g), peel weight (g) and pulp (g). The results showed that the doses of potassium fertilizer improved the response in passion fruit (Passiflora edulis), being that of 1cc of K per liter of water on leaf area (49 and 47.75 cm2) and T4 (7cc of K) on the number of fruits per plant (2.75). Regarding fruit physical characteristics, it was concluded that K doses influenced fruit diameter at 15 days (T2: 3 cc of K with 86.08 mm) and at 60 days (T5: 9cc of K with 76.52mm); for fruit weight at 30, 45 and 60 days (T4: 7cc of K with 185.11; 177.46 and 171.29 g), as for pulp weight at 15 days (T2: 3 cc of K with 114.76 g) and 30 and 60 days it was T5 (9 cc of K) that caused weights of 84.41 and 84.53 g.
