Development of Vigna unguiculata (L.) Walp submitted to concentrations of laminar and bovine composting

Abstract

The objective of this work was to evaluate the development of string bean (Vigna unguiculata) under two composting systems in different concentrations, the first one being leaf, litter and ground, the second being the base of cattle manure, ash and Earth. For the preparation of the experiment were used waste such as bags, crates and others, for the production of the compost. After the treatment preparations, they were diluted in sand to give the concentrations of 25, 50, 75 and 100% (v/v), where they were placed in PET containers and bean seeds were used to conduct the evaluations. Weekly evaluations were performed after the germination of each plant, and the height in centimeter (cm) was collected at weekly intervals. The data showed that the concentrations of insecticides showed higher growth, being the concentration of 75% had the best growth, independently of the type of compost. It is possible to observe that from the 42 to 49 days, the results of the treatments began to differ significantly, being also found that in the growth curves, these evaluations were those that presented the highest rates of development among the measurements. It is recommended for the cultivation of the bean-of-rope composting the base of mats.
