Production of Ornamental Pyramid Pepper With Reflective Material on Benches in Different Environments

Abstract

Pepper trees have great ornamental value due to the varied colors of their fruits. Thus, the objective was to evaluate the Pyramid cultivar's production in different cultivation environments using benches with reflective material. The experiment was carried out in two protected environments: a) agricultural greenhouse with 42-50% shade screen under the plastic film and b) agricultural screen with black monofilament screen with 18% shade. Inside the environments, the production system was tested with and without reflective material on the cultivation bench. The experiments were conducted in a completely randomized design, with four replicates and six plants per plot. Joint analysis was used to compare environments. At 45, 60, and 75 days after transplantation, plant height, stem diameter, number of leaves, canopy area, and number of fruits were evaluated. The agricultural greenhouse with a 42/50% shade screen under the plastic film provided the formation of higher plants with greater stem diameter, greater number of leaves and fruits, and greater top diameter than the screen with 18% shading. The reflective mirror material showed positive results only for plant height.

Silicon Mitigates the Attack of Pests and Diseases on Ipê-Roxo (Handroanthus impetiginosus) Seedlings

“…In hot climate regions, such as the one in the present study, the temperature inside the protected environment is strongly related to the precipitation of the period, and the greater and better distributed over time, the more similar the monthly averages of internal and external temperatures (Silva et al 2021b) as verified in the present study. In winter, the average monthly temperatures also tend to balance the internal and external environments (Paula et al 2017).…”

“…Both the Dickson quality index (Figure 4B) and dry matter of the Handroanthus impetiginosus seedlings (Figures 3B and 4A) were not influenced by the application of silicon, and the best seedlings were formed in full sun. With a significance level of 10%that is, with a 90% probability of occurrence-it was observed that silicon could minimize the severity of production environments, with significant differences, are related to the type of plastic covering film associated or not with the shading screen, as well as the individual use of the shading screen in coverage (Paula et al 2017;Silva et al 2021a;Silva et al 2021b).…”
