Initial growth and fruit quality of Physalis plants, fertilized with different doses of ovine vermicompost

Abstract

The experiment was conducted in a greenhouse at the Eliseu Maciel Agronomy College (FAEM)
of the Federal University of Pelotas (UFPel), Pelotas-RS, from October 2016 to March 2017, with
the objective of effect of different sheep vermicompost doses on initial development and fruit
quality of Physalis plants. The experimental design was completely randomized, with four treatments
and six replicates. The treatments consisted of the combination of four doses of ovine
vermicompost (30, 60, 90, 120 g pot-1). The following evaluations were carried out: height and
number of leaves per plant, stem diameter (above lap), leaf area, lateral and transverse diameter
of fruits, mean fruit mass, total soluble solids (TSS), fruit average pH, Total productivity. The ovine
vermicompost provided an increase in the growth rate of Physalis plants, especially from the
dose of 60g potassium-1. The fruits presented values of degree ° Brix high, being in the range
of 14,0°Brix. The pH of the fruits as the dose increases tends to be more acidic.
