MORPHOPHYSIOLOGICAL INDICES AND PEPPER PRODUCTION PRODUCED ON DIFFERENT SUBSTRATES BASED ON ORGANIC RESIDUES IN PROTECTED ENVIRONMENT

Abstract

The pepper (Capsicum annuum L.) is one of the ten vegetables of major economic importance in the Brazilian market. The use of substrate for pepper production is an alternative, for intensive use alone. And the demise of soil diseases that affect the production of this vegetable. The objective of this work was to evaluate morphophysiological indices and pepper production in different alternative substrates in the city of Paragominas, Pará. The experiment was carried out at the Federal Rural University of Amazonia, using an experimental design in a 5x2 factorial scheme with two cultivars, being substrate and two cultivars, the substrates being: 1 - control; 2 - Soya residue; 3 - rice straw; 4 - Black earth; 5 - Black soil + Rice straw + Soybean residue, and hard shell cultivars Ikeda and Rubi Gigantic and four replicates. With averages compared by the Tukey test at 1% probability. The plant height (cm), leaf diameter (mm), fresh mass (g), number of fruits, dry mass (g), foliar area, leaf area ratio (RAF) (AFP), leaf specific weight (PEF), amount of water in the aerial part (QAPA) and leaf area index (LAI). The cultivar Casca dura Ikeda presented satisfactory results, referring to the characteristics evaluated in the climatic conditions of the municipality of Paragominas. Regarding the substrate performance, the cultivar Casca Dura Ikeda presented better yield in the substrate soy residue. KEYWORDS: Alternate substrate, Capsicum annuum, Organic waste.
