Produção de rabanete com diferentes tipos de adubações orgânicas

Abstract

The radish (Raphanus sativus L.), as well as the other tuberous vegetables, stores in its root a significant percentage of nutrients present in the soil. It is extremely nutritionally demanding and nutritional deficits can hardly be reversed, which leads to a drastic loss in relation to production. It is of great importance to execute a proper management with the use of appropriate techniques to meet these needs. Organic fertilization is a sustainable and low-cost alternative for the producer, reducing environmental impacts and the use of chemicals. In this way, this research intends to evaluate the development of radish grown with different organic residues, of vegetable and/or animal origin. Four treatments were performed: T1 - Control; T2 - Vegetable fruit peel residues; T3 - Eggshell; T4 - Poultry litter. The experimental design was completely randomized, with three repetitions of each treatment. After 45 days, parameters such as fresh and dry shoot biomass, fresh and dry tuberous biomass, length of the main root, diameter of the tuberous root and plant height were evaluated. The data were evaluated by analysis of variance and the means between treatments compared by the Scott-Knott test at 5% significance. Radish plants grown with vegetable residues showed better growth and development, while the use of poultry litter significantly impaired the production of this vegetable.
