Desenvolvimento e acúmulo de biomassa na cultura do pimentão amarelo sob coberturas de solo e adubações.

Abstract

The nutrient content in plant tissues is responsible for the growth and development of plants and depends on various physiological, morphological and environmental factors. Therefore, plants conducted under favorable conditions tend to obtain higher yields due to the conditions offered. The objective of this work was to evaluate the development and accumulation of biomass in pepper plants under soil cover and organic and mineral fertilization types. The experiment was conducted at the Federal University of Campina Grande, located in the municipality of São Domingos - PB. The experimental design was in randomized blocks (DBC), in subdivided plots 4 x 5. The plots consisted of four soil coverages: C1 - soil covered with weeding (dry vegetation after weeding); C2 - ground carnauba straw; C3 - cobble and C4 without soil cover, subplots with five types of fertilization: A1 - 100% organic and 0% of mineral fertilization; A2 - 100% of organic fertilization and 50% of mineral fertilization; A3 - 50% of the organic fertilization and 50% of the mineral fertilization; A4 - 50% of organic fertilization and 100% of mineral fertilization and; A5 - 0% of organic fertilization and 100% of mineral fertilization, with four replications, each repetition consisting of five plants spaced 0.30 x 0.80 m. The organic fertilization was as a source of bovine manure and the dose incorporated into the soil was calculated based on the amount of nitrogen required for the crop. Up to 60 days after transplanting, plant height and number of leaves are increasing in favored yellow pepper plants with soil cover with weeding or with shavings. The production of biomass of plants and fruits of yellow pepper is increased with organomineral fertilization. Fertilization with 100% of the recommended dose with the use of mineral fertilizer without soil cover promotes lower plant height and leaf numbers until 60 days after transplanting and reduction in fresh mass of yellow pepper plants.
