DESENVOLVIMENTO INICIAL DA CANA-DE-AÇÚCAR FERTILIZADA COM ORGANOMINERAL DE LODO DE ESGOTO E BIOESTIMULANTE

Abstract

The culture of the sugarcane (Saccharum spp. L.) it is of great importance economic for the fact that Brazil is the largest world producer. The southeast stands out in this production, and the main states producers are São Paulo, Goiás and Minas Gerais. It is of addition importance to study the use of fertilizers mineral organic, because these generate great expectations as efficiency, economy, and sustainability of the manurings, the sewer mud (bio-solid) it is a solid residue resulting from processes of biological treatment of sewer, and it is one of the alternatives mineral organic for the fertilization of cultures of economical value. It was aimed at to evaluate the initial acting of the culture of the sugarcane, fertilized with mineral fertilizer and associated mineral organic the bio-stimulant, through of analyses vegetable covering of the soil, area to foliate of the culture, tillering, stem diameter and height of plants. The experiment was accomplished in the Federal Institute of Education, Science and Tecnologia Goiano - Campus Morrinhos - GO. The combinations of the treatments in function of the recommendation of planting manuring (470 kg have-1 formulated 04-21-07) during the cycles of the culture they were: 100% of the mineral source; 0; 60; 80; 100 and 120% (Without bio-stimulant) and 0; 60; 80; 100 and 120% (With bio-stimulant) source mineral organic of bio-solid. The different ones percentile of planting manuring they were indifferent as vegetable covering, area to foliate, stem diameter and height of plants, the bio-stimulant application promoted increments in the results of vegetable covering, tillering, and area to foliate of the sugarcane plants on the soil to 150 DAP.
