REYES-MORENO, Manuel et al. Fertilization in rambutan (Nephelium lappaceum L.) for improving the quality of the fruits. Ecosistemas y recur. agropecuarios [online]. 2020, vol.7, n.1, e2412.  Epub May 30, 2020. ISSN 2007-901X.  https://doi.org/10.19136/era.a7nl.2412.

The objective was to evaluate the effect of two fertilizer applied to productive rambutan trees (Nephelium lappaceum L.) including conventional edaphic fertilization, for improving the quality of the fruits. The treatments were: Biofertilizer more Bayfolan® (T1), Biofertilizer (T2), Bayfolan® (T3), without fertilizer (T4). The experimental design was completely randomized, with five repetitions and a tree as experimental unit. It was measured: appearance of the fruit (AF), color of the pericarp, loss of weight, firmness (F), fresh weight (FW), titratable acidity and oBx. The AP improved by 28% in T1 and in T3; the combination of fertilizers improved the quality of the fruit at harvest, up to 16% oBx and 10% in FW. The fruits of the remaining treatments lost weight (up to 35%) and F (up to 41%) to the eight days after the harvest. Conventional and foliar fertilization improve postharvest quality and shelf life of rambutan fruits.
