A crescente demanda de água para fins industriais e residenciais, geração de energia, mineração, lazer, somados aos problemas ambientais, faz com que quantidade de água para a agricultura apresente uma tendência de redução. A agricultura é o maior usuário de água em todo o mundo. O setor agrícola brasileiro é o principal usuário consuntivo dos recursos hídricos. Uma provável solução para esse problema é aperfeiçoar como a água é manejada, o que envolve a adoção de tecnologias e procedimentos ade ...

Many are the Brazilian regions which cultivate stone fruits (peaches, plums and nectarines), such as the surrounding areas of Pelotas - RS, the metropolitan region of Porto Alegre - RS, the Serra Gaúcha, the states of Santa Catarina, Paraná and São Paulo, passing by the south of Minas Gerais and Campos das Vertentes (Caldas, Poços de Caldas and Barbacena), the colder regions of Rio de Janeiro and Espírito Santo and, recently, in regions of higher altitude in the state of Bahia. In addition to th ...

The changes in climate behavior will probably bring changes to the hydrological cycle. As a result, these variations will probably affect crop development, crop production, and water consumption.
Therefore, the project’s proposal is to determine the water requirement for irrigation in the current weather and in different future climate scenarios for the cropping of pineapple and coconut in the North, and orange, in the Northwest of the state of Rio de Janeiro, Brazil, since those are the cro ...

Historically, the agricultural activities in the northeast of Pará have been concentrated in the hands of small farmers and family-based workforce, who dedicate themselves almost exclusively to subsistence farming with focus on yuca (Manihot esculenta), corn and caupi-beans (Vigna Unguiculata) as crops with most significant socio-economic expression. This practice is done with little or no use of agricultural supplies, such as lime and fertilizers, leading the region's lands, which already have ...

Brazil is a tropical country with an extensive territorial area and vast plant diversity. This makes the weed species that infest the crops be widely varied. Such characteristics differentiate Brazil from other countries with temperate climates. GM crops that are resistant to herbicides, especially to glyphosate, have created a new scenario for weed control in Brazilian agriculture. Farmers have adopted RR technology right away as efficiency and cost are its main benefits. The use of glyphosate

Wheat ( Triticum aestivum L.) is the world's second largest crop and Brazil has taken second place in wheat production in South America. However, productivity in this crop can be limited due to occurrence of some diseases, one of which, wheat blast, caused by the Magnaporthe grisea fungus, has caused large productivity losses that can reach 72% depending on the time of infection. With the expansion of wheat crops to other Brazilian regions such as the Midwest, the fungus has been settling in and

The tomato is one of the most cultivated vegetables in the world, and is the target of countless plant health problems. Embrapa Vegetables has historically produced research in plant health within this production chain under the scope of the Tomato Genetic Improvement Project. However, the increasing demand for studies aimed at perfecting pest diagnosis methods and generating essential information for management has signaled the need to create a specific plant health project. Thus, this project

The recent expansion of sugarcane's culture by the mid-southern states of Brazil (Paraná, São Paulo, Mato Grosso do Sul, Minas Gerais - except the north, and Goiás), has been mostly happening on areas where degraded grasslands occur, characterized by eroded soils which are poor in nutrients, under distinct hydric regimes in regions of traditional sugarcane production. The incorporation of these flat topography areas enables mechanized harvesting and a more intensive soil use, with the eliminatio ...
