Autores: Rosso,Ricardo B.; Peiter,Marcia X.; Robaina,Adroaldo D.; Ben,Luis H. Bahú; Mezzomo,Wellington.
ABSTRACT The need for crop rotation and profitability in lowland areas are the two main reasons for the introduction of soybean cultivation in the state of Rio Grande do Sul, Brazil. These areas have poor natural drainage, which impedes proper soybean growth. In this sense, this study aimed to assess the efficiency of using broad base ridges in comparison to the surface drainage for soybean cultivation in lowlands. The study was conducted during the 2014/2015 and 2015/2016 growing seasons in São João do Polêsine, RS, Brazil. The assessed drainage methods were the use of broad base ridges with different width dimensions (22.5, 15.0, and 7.5 m) and surface drainage. The results showed that the shoot dry matter and leaf area index have similar behavior. The...

First record of pantanal cat, Leopardus colocolo braccatus, in Bolivia
Provedor de dados: 81
Autores: Díaz Luque,José A; Beraud,Valerie; Torres,Pablo J; Kacoliris,Federico P; Daniele,Gonzalo; Wallace,Robert B; Berkunsky,Igor.
The Pantanal cat, Leopardus colocolo braccatus, has been reported for grasslands and subtropical humid forests in Brazil, Uruguay, Paraguay and Argentina. Here we report a dead Pantanal cat in the Moxos savannahs of the Beni Department of Bolivia, representing the first record of this taxon for Bolivia. This record, in combination with a reassessment of two previous records of L. colocolo in the lowlands of Bolivia, extends the distribution range of this subspecies ca.1000 km WNW from the nearest known locality in Brazil.

Planosol soil sample size for computerized tomography measurement of physical parameters
Provedor de dados: 63

Computerized tomography (CT) is an important tool in Soil Science for noninvasive measurement of density and water content of soil samples. This work aims to describe the aspects of sample size adequacy for Planosol (Albaqualf) and to evaluate procedures for statistical analysis, using a CT scanner with a 241Am source. Density errors attributed to the equipment are 0.051 and 0.046 Mg m-3 for horizons A and B, respectively. The theoretical value for sample thickness for the Planosol, using this equipment, is 4.0 cm for the horizons A and B. The ideal thickness of samples is approximately 6.0 cm, being smaller for samples of the horizon B in relation to A. Alternatives for the improvement of the efficiency analysis and the reliability of the results obtained...

Effect of root zone cooling and evaporative cooling in greenhouse on the growth and yield of potato seed by aeroponics in tropical lowlands
Provedor de dados: 111
Autores: Sumarni, Eni; Hardanto, Afik; Arsil, Poppy.
Temperature control of the rooting area with application of root zone cooling in an aeroponic system succeeded in maintaining the freshness of potato plant roots during planting to achieve tuber initiation. However, following the application of root zone cooling, many wilted plants that were burnt due to high temperatures above the plant surface remained. Therefore, effort is needed to improve the condition of the top of the plant, so that the growth of potato plants in the lowlands may be optimized. The results of some studies show that evaporative cooling can reduce the pressure of hot temperatures in the greenhouse and the area around the plant canopy. Therefore, integrated research on the aeroponic system for the application of root zone cooling and...
