Growth and production of yellow passion fruit in a soil of low fertility treated with liquid biofertilizers

Abstract

The effects of simple and supermagro liquid biofertilizer, applied in soil, on the vegetative growth and production of yellow passion fruit plants (Passiflora edulis f. flavicarpa Deg.) were evaluated from November 2002 to July 2003. The biofertilizer was applied at 30, 60 and 90 days after planting, in volumes of 0, 0.0.6, 1.2, 1.8 and 2.4 L plant^-1, corresponding to 0, 25, 50, 75 and 100% levels of 15 L m^-2 of water: biofertilizer proportion 1:1. Both biofertilizer simple and supermagro had no influence on time of pruning of the main stem, lateral branches and the number of productive branches. Supermagro  biofertilizer inhibited the stem diameter, mean weight of fruits and yield of yellow passion fruit in relation to simple biofertilizer.
