| Water is an important natural resource for the competitiveness of Brazilian agriculture. Since Brazil is rich in this natural resource, to preserve it and keep it in quantity and quality is strategic. Such a competency demands water efficiency, which is the relationship between the amount of yielded products and the amount of water used for such a production. This project evaluates the performance of water indicators from milk pasture-based and confinement-based production systems and of nutriti Status: Completed Start date: Fri Aug 01 00:00:00 GMT-03:00 2014 |
| Milk production systems have gone through a process of specialization characterized by increasing the size of the herds, productivity and, notably, by reducing the man: cow relationship. The downsizing of skilled labour in production systems demands the development of precision dairy farming tools that allow the generation of individualized data of animals in a given herd. For that matter, there is a need not only for sensors capable of identifying and generating data on individual animals, but Status: Completed Start date: Sat Mar 01 00:00:00 GMT-03:00 2014 |
| Agroforestry systems (AFS) combine planting trees with agricultural crops or animal husbandry and are considered suitable production systems for the Amazon region because they reconcile agricultural production with the conservation of natural resources, which is a great challenge today.

| Under the strong impact of the demand for energy and the need to develop alternative technologies to replace oil, the sugarcane industry is expanding and boosting interest in the assessment of both private and social costs and benefits in sugar and energy production. The importance of environmental issues in society has inserted this topic in the agenda of public and private planners through their concern with the preservation of water resources, soil fertility, and biodiversity, as well as with Status: Completed Start date: Sun Jan 01 00:00:00 GMT-03:00 2012 |

The TecRede project aims to generate technologies that would, in a short period of time, the development of tambaqui (Colossoma macropomum) cultivation in cage systems. The project chose the tambaqui to foment the development of cage fish farming since it is a fish native to Amapá, which has favorable domestic and international market demand, with production absorption capacity. The research network intends to determine the standardization of techniques and production systems based on Good Pr ...Status: Completed Start date: Fri Aug 01 00:00:00 GMT-03:00 2014 |
| Environmental systems (SA) have gained great visibility as mechanisms of environmental conservation and improvement of living conditions for rural communities. However, when compared to services of provision of food, fiber and energy, SAs such as carbon sequestration and water conservation are generally put in an inferior level. Given its importance even to the sustainability of agriculture, it is necessary that these SAs move from the sphere of discourse into the sphere of practical realities.

| The embryo transfer technique (ET) began to be used in Brazil in the 70's, based initially on in vivo embryo production (by conventional superovulation). The potential of the technique as a tool in the multiplication of superior genotypes or in breeding programs resulted in its rapid assimilation by the productive sector, with a consequent increase of its use in the following decades. In recent years, the development of the in vitro embryo production technology has revolutionized the national ma Status: Completed Start date: Thu Jan 01 00:00:00 GMT-03:00 2009 |
| 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 Status: Completed Start date: Mon Oct 01 00:00:00 GMT-03:00 2012 |
| Intensive production systems benefit the proliferation of phytopathogens and polyphagous insect pests by extending the period of host presence in the field.The chemical control of pests and diseases is the main tool used. Therefore, there is a relevant concern about the negative impacts of excessive dependence on only one control strategy. Questions such as: what are the effects of the excessive use of multisite fungicides on the soil microbiota; and which levels of metals (present in multisite Status: Completed Start date: Tue Sep 01 00:00:00 GMT-03:00 2020 |
| The presence of trees causes the interception of part of solar radiation in agricultural systems, mainly affecting shaded plants and variables such as energy balance, winds and water use by plants (Brenner, 1996). In addition to the restriction of solar radiation, there is also competition for water and nutrients near the row of trees (Magalhães et al., 2018). Thus, controlling competition for light among forest species and reducing tree drain strength for agricultural and forage crops can repre ...
