Application of agribusiness and agriculture residues in the culture of Raphanus sativus L.

Abstract

The waste generated by agribusiness and agriculture can pollute the environment when disposed of incorrectly. The reuse of this waste is a sustainable alternative, enabling an environmental, economic and social balance for the planet. This work aimed to evaluate the different doses of chicken litter and Stevia rebaudiana (Bert.) Bertoni residues in the culture of Raphanus sativus L. (radish). An experiment was carried out in pots with a completely randomized design with six treatments, containing organic compounds which were: (T1) red latosol, (T2) 100% of the residue of S. rebaudiana, (T3) 100% of chicken litter, ( T4) 75% of the residue of S. rebaudiana and 25% of chicken litter, (T5) 50% of the residue of S. rebaudiana and 50% of chicken litter and (T6) 25% of the residue of S. rebaudiana and 75 % of chicken litter, with 10 repetitions each treatment. The evaluation was carried out 25 days after planting the radish seedlings. The variables evaluated were biometric parameters such as plant height, root length, number of leaves, leaf area and dry matter weight. The chemical analysis of the S. rebaudiana residue showed a considerable amount of potassium, indicating the presence of an important nutrient for the culture of the radish. Radishes grown with 100% of the S. rebaudiana residue (T2), showed a growth and development of the aerial part and larger roots in relation to the other treatments. Plants that were grown in concentrations greater than 50% of chicken litter, on the other hand, died early in development. The use of this agroindustrial residue S. rebaudiana, suggested benefits to the culture of the radish and, also, as a correct way of destination of this compound in the environment.
