| This project aims to develop an enzymatic route for biodiesel production, using ethanol and palm oil as raw materials. Currently, biodiesel is obtained by a chemical reaction between an oil and an alcohol, accelerated by a chemical catalyst - mainly sodium hydroxide. The use of this catalyst, however, causes a number of problems, such as high energy consumption, difficult glycerol recovery and the generation of a large volume of effluent. In addition, it causes saponification when acid oils, suc Status: Completed Start date: Tue Jan 01 00:00:00 GMT-03:00 2013 |
| Agribusiness is one of the pillars of the Brazilian economy and a considerable part of the trade surplus achieved in recent years is due to exports of agricultural products . The product list is quite long , but some species are characterized by high demand and high production , such as soybeans , coffee and cane sugar.

| The culture of Palm Tree Oil ( Elaeis guineensis Jacq.) has great socio-economic importance in the state of Pará, the country's largest producer. This culture has risen the growth potential in Brazil, by its oil demand, great productivity and competitiveness when compared to other cultures, availability of altered areas prone to offer favorable soil and weather conditions, generate jobs and income, and protect the soil due to its perennial character. However, the fatal yellowing of palm o ... Status: Completed Start date: Wed Sep 01 00:00:00 GMT-03:00 2010 |
| Garlic cultivation has a major social impact, generating four direct and four indirect jobs per hectare planted in the production chain. More than 60% of Brazilian garlic production is in family-based properties. Since 2004, as planted area has been reduced to an average of 8,000 hectares, there was an estimated loss of 24,000 direct posts. In 2008, Brazil imported a volume equivalent to the production of 15,000 hectares, corresponding to 130,000 jobs outside Brazil. There has been a significant Status: Completed Start date: Sun Nov 01 00:00:00 GMT-03:00 2009 |

In family farming system, farmers and their families are responsible for agricultural work and for the management of small and medium property. Often, the low purchasing power of the majority and the lack of appropriate technical guidance make farmers adopt undesirable practices while growing maize. The range of satisfactory yields depends, among other factors, on a good soil fertility, seeding in appropriate times, an effective management of insect pests and diseases, and especially quality ...Status: Completed Start date: Sat Oct 01 00:00:00 GMT-03:00 2011 |
| The silvopastoral systems are a viable option to avoid degradation of pastures due to their potential to control erosion and the ability of some tree species to add nitrogen and other nutrients to the pasture, improving soil fertility. However, an important aspect in these systems refers to the competition for light between the tree/shrub and herbaceous components. Tiller production and the consequent density of inflorescences, directly related to seed production and, therefore, to natural resee Status: Completed Start date: Wed Aug 01 00:00:00 GMT-03:00 2007 |
| Brazilian native fruit species are excellent generators of income and job opportunities to family farmers and micro-entrepreneurs especially from the Northern and Northeastern regions of Brazil. Species such as the Platonia insignis, Myrciaria dubia, Byrsonima crassifolia and the Spondia mombin L. have been frequently cited as economically promising in the field of family farming, due to the myriad of business possibilities linked to the ever increasing demand of Status: Completed Start date: Fri Feb 01 00:00:00 GMT-03:00 2008 |
| The state of Pará is slowly adopting practices to modify altered areas by means of reforestation, and the agriculture producers have been requesting seeds and seedlings in order to apply Agro-forest Systems. However, a great obstacle to this program has been the lack of knowledge about seed germination technologies and seedling production, on a commercial scale and with quality standards. To address these deficiencies, this project aims to research native species with potential use in these syst ... Status: Completed Start date: Mon Dec 01 00:00:00 GMT-03:00 2008 |
| Ecological alternatives may contribute to the attainment of sustainability of productive family units through the balanced use of natural resources in the Amazon. Among these viable alternatives, stand out in the Amazon the initiatives of land preparation without the use of fire, such as the Tipitamba Project, the Roça without Fires Project, Agroforest Systems and agroecological alternatives practiced by the region's farmers. The availability of knowledge and practices through the training of en ... Status: Completed Start date: Tue Mar 01 00:00:00 GMT-03:00 2011 |

Smallholder Capsicum pepper growers in Uganda are operating below the ideal levels of agricultural production due to a lack of improved varieties, low quality seed systems and the devastation caused by pests and diseases. The damages caused by diseases are aggravated by the cultivation of susceptible germplasm and the use of poor quality seeds. In order to increase production and competitiveness in the market, farmers need to have access to clean seeds of cultivars that are tolerant to diseas ...Status: Completed Start date: Mon Jun 01 00:00:00 GMT-03:00 2015 |
