25. Inter-specific variability in protein use by two vegetable crop species
It is now well-known that plants can uptake not only inorganic nitrogen but also organic nitrogen compounds, mainly amino acids. However, soil proteins are the main pool of amino acids. According to our earlier papers, plants can get access to this source of nitrogen using root-secreted proteases, but the level of proteolytic activity of such root-secreted p

26. Monitoring of potassium in a culture of irrigated bell pepper in semiarid region / Monitoramento do potássio em um cultivo de pimentão irrigado em região semiárida / Monitoramento do potássio em um cultivo de pimentão irrigado em região semiárida / Monitoramento do potássio em um cultivo de pimentão irrigado em região semiárida / Monitoring of potassium in a culture of irrigated bell pepper in semiarid region / Monitoring of potassium in a culture of irrigated bell pepper in semiarid region
The bell pepper is of high importance within the vegetable crops, thus becoming an alternative source of income for small producers and family farms. Potassium is the nutrient most absorbed by bell pepper and diffusion the main transport mechanism to the roots, although the mass flow can have significant contribution in the process under high potassium conce

27. Desenvolvimento de um sistema de irrigação por microaspersão com microtubos para hortas agrícolas / Development of a microsprinkler system with microtubes for vegetable crops
A inovação tecnológica é o caminho mais viável para desenvolver uma agricultura sustentada no Brasil. Portanto, o país deve investir nos setores que possam produzir tecnologias inovadoras, adequadas as suas condições peculiares e de custo mais acessível, em substituição à dependência por produtos importados. Dentro desse contexto, este trabalho

28. Produtividade e qualidade de híbridos de tomate (Solanum lycopersicum L.) dos segmentos Santa Cruz e Italiano em função do raleio de frutos, em ambiente protegido / Yield and qualitative characterization of tomato (Solanum lycopersicum L.) hybrids of Santa Cruz and Italian types in function of fruit thinning under greenhouse environmental conditions
The objectives of this work were to determine the effect of cluster thinning on yield and its components on tomato hybrids of the Santa Cruz and Italian types of indeterminate growth, and to perform the qualitative characterization of the fruits, aiming at in natura growth. Treatments consisted of 12 indeterminate fresh-market tomato cultivars (six experimen

29. Uso de reguladores de crescimento e controle biológico de fungos no feijoeiro cultivado em sucessão à diferentes culturas de cobertura / Use of growth regulators and biological control of fungi in the common bean cultivated in succession to different cover crops
Visando aumentar a produtividade do feijoeiro várias tecnologias são oferecidas, mas faltam estudos para verificar a eficiência destas. O objetivo deste trabalho foi avaliar o efeito de regulador de crescimento e o controle biológico de fungos do solo por meio de Trichoderma sp., visando maior produtividade do feijoeiro irrigado em sucessão à diferente

30. Uma reflexÃo sobre os possÃveis impactos do crescimento da demanda dos biocombustÃveis na oferta e preÃos das commodities agrÃcolas
The food market has changed. The use of liquid biofuels as an alternative to fossil fuel changed the crop and vegetable oil international markets, adding an important consumer sector of the economy: the energy sector. The rapid growth of biofuels demand and supply has a number of effects on the crop and vegetable oil markets, pressuring upward the agricultur

31. Conformação da qualidade microbiológica em couve minimamente processada no Distrito Federal : o caso da Agroindústria Machadinho
The trade of vegetable crops has changed substantially in the last years. Quality and presentation of the products are the most important facts in this change. Minimally processed vegetables are those that have been physically changed but have kept their fresh condition. The successive manipulation increases the chance of microbiological contamination of the

32. Uso de reguladores de crescimento e controle biológico de fungos no feijoeiro cultivado em sucessão à diferentes culturas de cobertura / Use of growth regulators and biological control of fungi in the common bean cultivated in succession to different cover crops
In order to increase the productivity of the common bean crop several technologies are offered, but there is lack of studies to verify their efficiency. The objective of this work was to evaluate the effect of growth regulator and the biological control of fungi of the soil through Trichoderma sp., seeking larger productivity of the commom bean plant irrigat

33. Condicionantes da viabilidade de produção do biodiesel a partir do dendê e do pinhão-manso no semi-árido brasileiro / Guidance to feasibility of biodiesel production after the palm and jatropha curcas in the brazilian semi-arid
There is a wide guidance to the worlds attention in the adoption of biofuels. High oil prices and global warming are among the main ones. Under this scenario, several countries have invested in research to find a source of clean energy produced in a sustainable context. Among them is biodiesel made from vegetable oils. In Brazil, after the institutionalizati

34. Efeito de diferentes doses de silício, nitrogênio e potássio na incidência da traça-do-tomateiro,pinta-preta e produtividade do tomate industrial
Tomato production is at second place among vegetable crops in Brazil in economical relevance. This crop is exposed to many pests that limit yield. The aim of this research was to evaluate silicon, nitrogen and potassium effect on blight infection, tomato pinworm injuries and yield. The experiment was carried out at FAL- UnB in a completely randomized design,

36. Integração das estratégias de controle químico e biológico para a conservação e liberação dos ácaros predadores Neoseiulus californicus (McGregor) e Phytoseiulus macropilis (Banks) (Acari: Phytoseiidae) em programas de manejo do ácaro rajado Tetranychus urticae Koch (Acari: Tetranychidae) / Integration of chemical and biological control strategies for preserving and releasing Neoseiulus californicus (McGregor) and Phytoseiulus macropilis (Banks) (Acari: Phytoseiidae) in Tetranychus urticae Koch (Acari: Tetranychidae) management programs
The exploitation of predaceous mites to manage phytophagous mites in agricultural production systems can be affected by the use of pesticides for controlling other pests and diseases. The use of pesticides that are compatible with predaceous mites or pesticide-resistant strains can promote the conservation of these natural enemies. Another strategy to be exp
