glyphosate application in burndown of biomass sorghum
The sorghum biomass is an alternative to a renewable energy generation by burning it in boilers, it stands out for its high productivity that occurs fully mechanized way. A common alternative to reduce the crop moisture is the application of herbicides. However, there is no researches showing the moisture reduction with burndown applications. Thus, this work aimed to evaluate the glyphosate application in drying of sorghum biomass. The experimental design was completely randomized in a factorial 2x5x4 consisting of: two cultivars of sorghum biomass (BRS 716 and CR 1342); five glyphosate doses (0, 720, 1,440, 2,160 and 2,880 g of the active ingredient ha-1) and four samplings of plants (7, 14, 21 and 28 days after application), with four repetitions. During the different samplings of plants were carried out evaluations of fresh and dry stem and dry matter percentage of culms. The application of glyphosate doses were not effective in the burndown process of biomass sorghum cultivars BRS 716 and CR1342.
