Custo de produção de mudas de seringueira em bancada suspensa com utilização de substrato e impactos na implantação de seringais.

Abstract

Good agricultural practices start in agricultural nurseries, from seed selection to to quality seed marketing. São Paulo state’s law requires rubber tree seedlings to be free of nematodes and seed and bubble propagation materials not only to have good physical, physiological and sanitary quality, but also a well known and proven genetic origin. Seedling production using a substrate in a suspended nursery presents these characteristics. The objective of this work is to evaluate the cost of rubber tree seedling production under this system and to present eco-nomic result indicators for the activity using the operating cost methodology. It also aims to present a simulation of the impact of this technology on the cost of establishment of a rubber tree plantation. The results show a good profitability for seedling producers, although, at first, higher production costs are expected during the establishment phase, an issue that needs to be evaluated taking into consideration the benefits to be presented by this technology.
