Joint research conducted by the National Soybean Research Center of Embrapa, Brazil, and the department of Biological Systems Engineering of University of Nebraska, Lincoln, was aimed at the design and development of new thresher/harvester concept for soybeans and other grain crops. The research, wich also was supported by ROTA industry of farm Machinery, from Brazil, resulted in an experimental prototype for threshing/harvesting soybeans and rice from standing, uncut plants. It used impact energy provided by nylon cords, fixed in a spiral path on opposite rotating shafts, striking the soybeans and the rice seeds from both sides of the plant row in upward direction. The device threshed 95.4% of the soybeans at average ground speed of 6.6km/h, being statiscally lower than 99% threshed at 3km/h. On the other hand, 25.8% of the material other than grain (MOG), removed at 6.6km/h, also was significantly less than the 32.1% of MOG remove at 3km/h. The 76.3% seed vigor value obtained at 6.6km/h was not significantly different from the 78.5% vigor of the hand threshed, but was significantly higher than the 67.1%, and 63.5% seed vigor values obtained when threshed by the device at 3km/h, and by a conventional combine, respectively. Tetrazolium and hypochlorite tests indicated that the numbers of mechanically damaged seeds caused by hand threshing and by the device working at the observed ground speeds, were not significantly different. However, they were statistically lower than the mechanically damaged and broken seeds resulting from conventional combining. The estimated average energy/ha required by the threshing device was approximately 4 MJ/ha, or about one-eight of that required by the tangentially fed threshing cylinder and concave of conventional combines. Preliminary tests with dryland rice showed 99.1% threshing efficiency and 8.6% MOG removed at a ground speed of 3km/h.

Biometric features and oil contents of macauba (Acrocomia aculeata) palms natively growing in sites representatives of the Brazilian Cerrados (Campo Grande ? CG, and Sao Gabriel do Oeste ? SGO), and Pantanal (Corumba ? CO, and Aquidauana ? AQ) biomes were studied. The objective was to obtain data that could assist better planning for the exploitation of natural populations, and knowledge to help selection and breeding programs. Plant (spines presence; stem circumference; number and length of bunches) and fruits characteristics (fruits per bunch; size; mass; proportion of components ? husk, pulp, shell and kernel; fruits moisture at ripening; pulp and kernel oil content) were measured from ten native palms from each site. There was variability in biometrics, biomass production potential and oil yield in the palms within each site and among the sites. No correlation was found between biometrics features and oil contents. On average, plants from CG showed better general productive characteristics than any other of the studied sites, but a large variability in fruits size. Palms from CO presented smaller fruits, but they were more homogeneous in size and with higher kernel oil contents. Fruits from SGO show bigger mass and size, but it did not result in higher fruit biomass production or oil yield. Although oil yields potential were almost half of what is usually measured in other areas of Brazil, results provided interesting data for a better planning to rational exploitation of native macauba groves in these areas. Variability within plants from all sites indicate that they could be a reserve of genetic materials for further development of cropping systems aiming production of oil and other useful products.
