Abstract

The use of organic fertilizers is essential for the sustainable production of vegetables. In this context, the aim of this study was to evaluate the effect of different doses of cattle manure on plant nutrition, yield, extraction and exportation of nutrients in the snap bean cultivar “macarrão trepador”. The experiment was held in EPAMIG-southeast, in Oratório-MG. The randomized block design was used, with four replications and five doses of cattle manure (0, 10, 20, 40 and 80 t ha-1). The content of nutrient in the leaves, yield components and the extraction and exportation of nutrients were evaluated. The content of all nutrients are in the adequate range, except for K and Ca. The extraction and exportation of nutrients raised with the growing doses of cattle manure. The application of 67.5 t ha-1  of cattle manure provided the highest yield, in which the quantity of each nutrient exported by pods were 45.6 (N), 5.2 (P), 16.1 (K), 4.6 (Ca), 3.8 (Mg) and 2.02 (S) in Kg.ha-1 and of 88.8 (Zn), 89.5 (Fe), 100.5 (Mn), 11.4 (Cu) and 33.1 (B) in g.ha-1. The greatest values for pod length (14.51 cm), number of pods per plant (58.34) and yield (14.86 t ha-1) were estimated with 56.7, 66.6 and 67.5 t ha-1 of manure, respectively. The application of cattle manure fertilizer improves the nutritional state of plants and yield, which, in this study, soared from 7.56 t ha-1 in the control to 14.86 t ha-1. These results are promising for the organic cultivation and sustainability of the production systems.
