SWEET SORGHUM IN DIFFERENT ROW SPACING AND PLANT DENSITIES IN MINAS GERAIS STATE, BRAZIL

The objective of this study was to evaluate the productivity and quality of the juice of sweet sorghumcultivars at different row spacings and plant densities. Experiments were carried out in three localities of Minas GeraisState, Brazil. In each site the trial was conducted in a randomized complete block design, in a factorial 2 x 4 x 4 scheme,with four replications, comprising two genotypes (BRS 506 and BRS 507), four plant densities (100, 140, 180 and 220thousand plants ha-1), four row spacings (50, 70, 90 and 110 cm) and three locations in the State of Minas Gerais (NovaPorteirinha, Leme do Prado and Jaíba). Plant height, productivity of green matter, juice yield and Brix of the juicewere analyzed. The increase in population provided higher productivity of green matter and juice in the two cultivars.The location affected the green matter productivity, juice productivity and Brix of sweet sorghum, independent ofplant arrangement. Reduction of row spacing caused higher productivity of fresh mass and juice mass as a function oflocation.
