Production and Quality of Okra Fruits Submitted to Doses and Types of Biofertilizers

Abstract

This study aimed to evaluate the yield and the quality of the fruits of two okra cultivars (Abelmoschus esculentus), due to the varying doses and types of biofertilizers. The experiment was conducted the period September to December of 2017, at the experimental Piroás Farm, in the city of Redenção-CE, Brazil. The experimental design used was entirely randomized, in factorial design 5 × 2 × 2, referring to the five doses of the biofertilizer (0, 0.5, 1, 1.5 and 2.0 L plant-1 week-1), versus two types of liquid biofertilizers (bovine and caprine under aerobic fermentation) and two okra cultivars: Santa Cruz 47 and Clemson Spineless. The number of the fruits per plant, the average mass of the fruits, yield, the length and diameter of the fruit and peel thickness of the okra fruit, were increased according to the increase on the biofertilizers doses. The cultivar “Santa Cruz 47” presented higher values in the length of the fruit, whereas the cultivar “Clemson Americano 80” was superior in the variables “average fruit mass” and “diameter of the fruits”.
