Resumo: A sorghum (Sorghum bicolor (L.) Moench) field experiment was carried out in the experimental area of Botany Department of ESALQ/USP, in Piracicaba, SP, Brazil, during 1983/1984. The growth of BR 501, BR 503. BR 505 and CMS x S 623 cultivars of sorghum was compared through growth analysis; the concentration of macronutrients in leaves was determined, and technological analysis of stalks during maturity period was realized. Cultivar BR 503 showed highest biomass production, presenting highest values of dry matter production DMP), net assimilation rate (NAR), and relative growth rate (RGR); cultivar CMS x S 623 presented lowest biomass production. The order of nitrogen concentration decreased on leaves of CMS x S 623 > BR 503> BR 505> BR 501 cultivars. The concentration of P was higher on BR 501 and BR 505 cultivars than in CMS x S 623 and BR 503 cultivars. The order of potassium concentration decrease on leaves was BR 505 > BR 501 > BR 503 > CMS x S 623 sorghum cultivars. Cultivars BR 505 and BR 501 showed best technological characteristics for alcohol production.

Comparou-se a produtividade das cultivares de sorgo sacarino (Sorghum bicolor (L.) Moench) BR 501, BR 503, BR 505 e CMS x 5623,através da análise de crescimento; estabeleceu-se o nível de macronutrientes nas folhas através da análise nutricional; e efetuou-se a análise tecnológica dos colmos durante a maturidade. A cultivar BR 503 mostrou maior produção de biomassa, pois apresentou os maiores valores de taxa de produção de matéria, seca (TPMS), taxa assimilatória líquida (TAL) e taxa de crescimento relativo (TCR); e a cultivar CMS x S 623 revelou baixa produção de biomassa. A percentagem de N nas folhas das cultivares decresceu na ordem CMS x S 623 > BR 503 > BR 505 > BR 501; os níveis de P mostraram-se mais altos nas cultivares BR 501 e BR 505 do que nas cultivares CMS x S 623 e BR 503; os teores de K decresceram na ordem BR 505 > BR 50l > BR 503 > CMS x S 623. As cultivares BR 505 e BR 501 apresentaram as características tecnológicas mais adequadas para a finalidade de produção de álcool. Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCastro, Paulo R.
