Nutrient accumulation curves help us understand the nutritional demands of a crop. The aim of this study was to evaluate the growth and accumulation of macronutrients by the sweet sorghum cultivars CVSW80007, CVSW80147, CVSW82028, CVSW82158. The experiment was conducted in a renewal sugarcane ratoon area at Uchoa county, SP, being deployed in January 2012. The plants were collected in 15 days intervals from the 10th after emergence (DAE). The greatest content of dry matter, N, P, Mg and S, was due to by the CVSW82028 cultivar, while the CVSW82158 extract the greatest amount of K and the CVSW80147 of Ca. The stalks represented the highs percentage of dry matter and nutrient content, except nitrogen and phosphorus, in which grains corresponded to the higher percentage of total absorption. The CVSW80007, CVSW82028 and CVSW82158 cultivars showed the following decreasing nutrient extraction N>K>Ca>Mg>P>S and the CVSW80147, K>N>Ca>Mg>P>S. Considering only the stalks harvest, the decreasing nutrient exportation is the same for all cultivars: K>N>Ca>Mg>S>P. Whereas the decreasing nutrient exportation sequence considering stalks and grain harvest is the following for the CVSW80007, CVSW80147 and CVSW82158 cultivars: K>N>Ca>Mg>P>S and K>N>Ca>Mg>P>S for the CVSW82028.

Due to its nutritional characteristics sorghum has been indicated as substitute cereal to corn and wheat. Besides, in Brazil sorghum is not used for human feeding unlike corn, witch reduces its costs in almost 20% in comparison to corn costs. This research was conducted at UNESP, in Botucatu and Jaboticabal Campus, São Paulo, Brazil, with the purpose to evaluate the grinding effect on two sorghum genotypes grain (with and without tannin) preserved dry or ensiled humid above the degradability in situ of the dry matter, crude protein and starch. Three rumen fistulated sheep were used, distributed in an experimental block design, at 2 x 2 x 3 factorial outline, with two sorghum genotypes (with and without tannin), two forms of conservation (dry grain and high moisture grains silage) and three grinding ways (undivided, thick grinding and fine grinding) and the time as sub-portion. According to the results the grinding is recommended to sorghum grains because it increases the ruminal and effective degradability of the dry matter, crude protein and starch. The presence of tannin in sorghum grain changed the degrability potential of crude protein and starch. The thick grinding in dry grain without tannin was the better treatment.
