Avaliação agronômica de cultivares de sorgo biomassa

Abstract

The strong demand for energy has led to the search for alternative sources recently biomass has been used to generate electricity in cogeneration systems. Thus, the sorghum biomass becomes a prominent culture for power generation, as it has several advantages in relations to other cultures, as its rapid growth and especially for presenting a high productive potential. This study was established to evaluate 36 biomass sorghum cultivars developed by the breeding program of Embrapa Maize and Sorghum. The experiment was conducted at White Grass Farm belonging to the Federal University of Uberlândia, located in Uberlândia, MG. Each experiment consisted of 36cultivares whose experimental design was a randomized complete block design with three replications. The plots consisted of two rows of 5 m long, spaced 0.50m. Data were submitted to analysis of variance (ANOVA) by F test and to compare the means by Scott-Knott test at 1% significance level. Data analysis was performed by the computer program, GENES. The characteristics evaluated were: plant height, total panicle weight, total green mass weight (without panicle), total dry weight (without panicle) .Among encoded Hybrids can be said that the vast majority showed a significant result for the experiment. Among the commercial hybrids, the one who stood out positively was the BRS716.
