Potassium fertilization in the cultivation of sour passion fruit under irrigation strategies with brackish water/Adubacao potassica no cultivo de maracujazeiro-azedo sob estrategias de irrigacao com agua salobra.

Introduction Sour passion fruit (Passiflora edulis) is a fruit crop of great socioeconomic importance and has stood out mainly among small and medium producers. Its

Article Description

This work had the objective to evaluate the effects of irrigation water salinity (EC) associated to application frequencies of bovine biofertilizer on chemical qualities of yellow passion fruits. The treatments were distributed using 5 × 4 factorial design corresponding the five EC of irrigation plant water of 0.5, 1.5, 2.5, 3.5 and 4.5 dS m, in four frequencies of application of the biofertilizer: without bovine biofertilizer (SB); with application one week before transplanting (1 SAT); application with intervals of 90 days after transplanting (90 DAT); and, with application one week before transplanting and at intervals of 90 days (1 SAT + 90 DAT). From the results it is verified that the increased salinity of water inhibited the pulp yield, the total soluble solids (TSS), pH, the ratio of total soluble solids and titratable acidity (TSS/AT) and vitamin "C"in juice, providing increased acidity and electrical conductivity of the juice. The increased frequency of application of the biofertilizer, despite increasing the electrical conductivity of the juice diminished the degenerative effects of salts of irrigation water to plants, resulting in an increase in pulp yield, vitamin "C" and also reduced the ratio TSS/AT and the pH of the pulp of yellow passion fruit.
