| O aproveitamento de resíduos agroindustriais tem motivado muitos estudos e aplicações, podendo-se extrair desses materiais compostos como polissacarídeos, lipídeos e proteínas com valor comercial. Esses resíduos, ou subprodutos, são matérias-primas disponíveis, geralmente de baixo custo e seu uso diminui o impacto ambiental gerado pelo seu descarte. Óleos são materiais tradicionalmente obtidos de subprodutos como as sementes de frutas geradas após a extração da polpa. Atualmente, graças a vários programas de incentivos públicos, como, por exemplo, o Programa de Aquisição de Alimentos (PAA), em sinergia com cooperativas e associações de produtores familiares, o processamento de frutas nativas tem aumentando (Araújo et al., 2016). Isso tem despertado o... |

| ABSTRACTThis study aimed to evaluate the residual effect of sewage sludge fertilization on yield and nutrition of sunflower in its second cycle. The experiment was carried out from April to August 2012. The treatments consisted of four doses of sewage sludge (0, 10, 20 and 30 t ha-1, dry basis) applied in the first cycle of sunflower, distributed in a randomized block design, with six replicates. Sunflower stem diameter, plant height, capitulum diameter and yield increased with the increment in sewage sludge doses, with maximum values observed with the dose of 30 t ha-1. The contents of calcium and magnesium in the soil, pH, sum of bases, effective and potential cation exchange capacity and base saturation increased, while potential acidity and the... |

| ABSTRACT Peeling of crambe fruits, besides increasing the yield of mechanical oil extraction, can increase its apparent specific mass from about 330 to 700 kgm−3, reducing transport and storage operating costs, as well as increasing cake protein content. However, there is no information on the quality of the oil extracted from the stored unpeeled crambe. This study aimed to assess the possible effects of peeling fruits submitted to different storage systems. For nine months, peeled and unpeeled crambe fruits were stored in conventional (permeable) and hermetic packages and water content, fatty acid, and acidity and oil peroxide indices were monitored. The experimental design was a completely randomized design in a 2 x 2 x 3triple factorial, with three... |

| The study which follows is an ex-ante analysis of expected returns to investment in agricultural research on groundnuts and sesame in Uganda. Studies have shown that it generally takes a minimum of six to ten years for new technologies to begin to have an impact on agricultural production practices. In the case of Uganda, Michigan State University was asked to measure the impact of a program which only began the process of rehabilitating the collapsed national agricultural research system in 1985 and began support for commodity research on groundnuts and sesame as recently as 1989 and 1991. As a result, the assessment which follows relies upon the projection of expected future benefits. While every effort has been taken to make reasonable projections based... |

| Biotech crops have now been grown commercially on a substantial global scale since 1996. This paper examines the production effects of the technology and impacts on cereal and oilseed markets through the use of agricultural commodity models. It analyses the impacts on global production, consumption, trade and prices in the soybean, canola and corn sectors. The analysis suggests that world prices of corn, soybeans and canola would probably be, respectively, 5.8%, 9.6% and 3.8% higher, on average, than 2007 baseline levels if this technology was no longer available to farmers. Prices of key derivatives of soybeans (meal and oil) would also be between 5% and 9% higher, with rapeseed meal and oil prices being about 4% higher than baseline levels. World prices... |

| High tariff and nontariff protection of the Indian oilseed sector imposes costs on consumers, supports an inefficient processing industry, and has led to negligible gains in oilseed output. Model-based simulations indicate that higher levels of protection would increase the burden on consumers, but do little to meet key policy goals of supporting producers and reducing import dependence. A shift to direct support of oilseed producer prices would increase output, but may be complex to implement and subject to WTO discipline. Liberalization of oilseed imports, by permitting large gains in processing efficiency, could generate a stream of benefits that would allow producers, consumers, and processors to be better off, and also improve the trade balance. |

| O pinhão-manso (Jatropha curcas L.) é uma oleaginosa que apresenta grande potencial produtivo para a região semiárida, podendo ser cultivado para a produção de óleo biodiesel. Contudo, seu cultivo necessita de estudos para se estabelecer e validar práticas adequadas de manejo. O objetivo deste estudo foi avaliar o desenvolvimento de plântulas de pinhão-manso submetidas a diferentes condições de estresse hídrico na região semiárida. O estudo foi desenvolvido em área experimental da Embrapa Semiárido, em Petrolina, PE. Sementes de pinhão-manso foram plantadas em vasos de polietileno contendo 8 L de solo e submetidas a diferentes níveis de reposição hídrica (100%, 75%, 50% e 25%) baseados na capacidade de campo (CC do solo). Quanto maior o estresse, menores... |
