Choosing species with high phytomass production to be cropped in no tillage system is extremely important in dry winter regions. The purpose of this research was to study plant biomass production and accumulation of nutrients in shoots of Giant Guinea sorghum plants (Sorghum bicolor subspecies bicolor race Guinea) sown in different sowing dates. A randomized complete block design with six treatments and four replications was performed. Treatments consisted of six sowing dates (09/25/2000; 10/25/2000; 11/24/2000; 12/22/2000; 02/22/2001 and 04/03/2001). At flowering, dry matter production, number and diameter of stems and plant height were evaluated. Macro and micronutrient levels and accumulation were determined as well as C/N ratio. Plant cycle decreased as sowing date was delayed and, consequently, dry matter production and C/N ratio decreased as well. The opposite was observed for nutrient contents. ?Giant Guinea? sorghum is sensitive to photoperiod thus late sowing reduces plant development, which leads to low biomass production and nutrient accumulation. ?Giant Guinea? sorghum cultivated as cover crop is a good option when implementing no tillage system due to high dry matter production and N, P, and K recycling. |

The use of timber forest resources has historically been a source of income and livelihood for families in lowland forests in the Brazilian Amazon. However, many of these woods are used without the knowledge of their properties. Studying the technological properties of these species is fundamental to subsidize their use and management, especially in shorter cycles of forest asset utilization. The objective of this research was to characterize the physical properties of the wood of Calycophyllum spruceanum of 12 years of age. The analysis were performed according to the radial position of the trunk (medulla-bark direction) and the traction wood and opposite wood, marked by the eccentricity of the medulla. Four trees were harvested for sampling and were furthermore analyzed. The density of the wood increased in the radial direction, with higher values closer to the bark. There were no significant differences between the two types of wood, traction and opposite, for the physical properties. |
