Multiplicação de cana-de-açúcar pelo método de mudas pré-brotadas (MPB)

Abstract

With the advancement of the sugarcane industry, sugarcane planting became mechanized and required a large amount of stalks to plant a new area. The activity became increasingly competitive and, in this scenario, small producers were losing space due to the difficulty of accessing machinery and quality planting material. Due to the high demand for stalks in the conventional system, the Agronomic Institute of Campinas (IAC) developed the Pre-sprouted Seedling (MPB) production system, which allows a great reduction in the demand for stalks, in addition to providing seedlings with high vigor and phytosanitary standards. This alternative can allow small producers to remain in the activity. The present work aimed to reproduce the methodology of sugarcane multiplication by the MPB method at the School Farm of the State University of Maranhão-UEMA, Paulo VI campus, and to disseminate this technology to students of Agronomy, Animal Science and producers. The following steps were performed: removal of the stalks, cutting and preparation of sugarcane mini-stems, treatment of the buds, sprouting, individualization, acclimatization 1, acclimatization 2, and dissemination of the MPB method through a lecture. To prepare the seedlings for demonstration purposes, 1056 mini-stems were sown in trays, of which 770 sprouted, obtaining 73% sprouting. Of these sprouts, 720 became viable seedlings (93.5%). Lectures and field visits were given to 19 agronomy and animal science students
