Application times and doses of bovine and sheep biofertilizers in the morphophysiological characteristics of green pepper plants

Abstract

This study aimed to evaluate the morphological characteristics and leaf area of Solário hybrid green pepper plants under different doses and times of application of organic fertilizers based on manure and enriched organic compounds. Two experiments were carried out with applications of organic fertilizers based on manure and enriched organic compounds, using bovine manure (CBF) and sheep manure (SBF). A randomized block experimental design was used was in factorial scheme 4 x 3 + 1, with three replications, composed by the doses of biological fertilizers (100, 200, 300 and 400 dm³ ha^-1), application times (0, 30 and 60 days after transplantation - DAT) and control. The following variables were evaluated: plant height (AP); canopy width (LC); stem diameter (DC); leaf number (NF); leaf length (CF); leaf width (LF); and leaf area (PA). The dose of 100 g L^-1 of Bovine biofertilizer (CBF) applied at 30 and 60 DAT is indicated for hybrid green peppers cv Solário cultivation since it promoted greater expansion of leaf area. Bovine and sheep fertilizer are indicated to promote plant height, canopy width, stem diameter and number of leaves in hybrid green pepper cv Solário plants.
