| Resumo: Uma representação acurada do território é crucial para uma avaliação adequada da sustentabilidade da produção de alimentos e bioenergia. No Brasil, três culturas com ambos os usos (soja, milho e cana) ocupam 3/4 da área agrícola do país. A área de uso agropecuário da terra, a frequência de cultivo e a área de cultivo na segunda safra são parâmetros essenciais para um grande número de modelos de uso da terra. Entretanto, os autores detectaram inconsistências nas estimativas da FAOSTAT e da literatura quanto a esses parâmetros. O objetivo deste trabalho é apresentar os resultados de uma iniciativa conjunta entre a Embrapa e a FAO para atualizar esses parâmetros com base em estatísticas oficiais. A atualização dos dados da FAOSTAT levou a uma mudança... |

| Faced with the imminent opening up of the trade in México in 2008, cultivation sugar cane (Sacchrum spp.) It has a strong competitive pressure from other producing countries that are operating with cost and low prices. Hence the need to seek production alternatives that could improve the profitability and competitiveness of this crop. For this propose was raised in this paper which compares the production systems of drip irrigation (high-tech) and irrigation by gravity (traditional technology). To performe the evaluation was used prior to the technical evaluation methodology for determinig the financial Internal Rate of Return (IRR) and Net Present. To make risk analysis, Trusts Institutions regarding Agriculture, it was used two packages that use computer... |

| We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market, multi-commodity international FAPRI (Food and Agricultural Policy Research Institute) model. The model incorporates the trade-offs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade. We examine land allocation by type of crop, and pasture use for countries growing feedstock for ethanol (corn, sorghum, wheat, sugarcane, and other grains) and major crops competing with feedstock for land resources such as oilseeds. We shock the model with exogenous changes in ethanol demand, first in the United States, then in Brazil, China,... |

| ABSTRACT The cultivation of sugarcane hybrids (X Saccharum officinarum L.) is an important revenue source for the Brazilian economy. Herein it is reported the evaluation of the cytotoxic activity of mid-polarity sugarcane extracts against human cancer cell lines, as well as the isolation of steroids sitosterol, stigmasterol and campesterol, phenolic acids p-hydroxybenzoic, p-hydroxycinnamic, vanillic and ferulic acid, terpenoids α-tocopherol and β-carotene and a novel substance in sugarcane, the flavonoid aglycone tricin (5,7,4-trihydroxy-3,5-dimethoxyflavone). The presence of large amounts of phenolic acids and the flavonoid tricin may explain the cytostatic activity observed for the mid-polarity crude extract and filtrates. |

| Abstract: Sugarcane is a major commercial crop grown in India and across the world. Hence, several elite varieties have been developed now-a-days to overcome many obstacles including abiotic stresses and diseases. The present study was undertaken to screen genetic variation among twenty four sugarcane varieties that are commonly cultivated across Northern Karnataka, India with reference to physicochemical characters. Experiment was conducted in triplicate following randomized complete block design (RCBD) at S. Nijalingappa Sugar Institute, Belagavi, Karnataka, India during February 2016-17. Physiological parameters such as internode length, stalk height, plant height, stalk girth, number of internodes, single cane weight, single cane volume of juice, cane... |
