Agriculture in Brazil is a means for promoting significant socioeconomic sustainable progress. However, the productivity of cereal crops such as maize, rice, wheat and sorghum is below their potential. The low availability of phosphorus (P) and inadequate fertilization are some of the major challenges of modern agriculture. In tropical soil, the phosphorus is carried out by adding high dosages of water-soluble phosphates, since most of the added fertilizer becomes unavailable because of fixat ...Status: Completed Start date: Mon Oct 01 00:00:00 GMT-03:00 2012 |

Precision farming and agricultural practices that take into consideration the protection of the environment have brought forward a number of research challenges. The scale of sampling and the precision required by such new agricultural practices are often higher than those required by traditional agriculture, increasing production costs. Methods and devices for on-the-go measurements are being developed to equip agricultural vehicles to support these practices. The proposed project was guided ...Status: Completed Start date: Mon Sep 01 00:00:00 GMT-03:00 2008 |
| Embrapa has built a highly conducive environment for the use of strategic and competitive intelligence to support action planning and scheduling and to provide important information to the different agents in the supply chains to which it relates. This is expressed in Embrapa's Agropensa (Strategic Intelligence System) dedicated to producing and disseminating knowledge and information in support of the formulation of research, development and innovation strategies for the corporation and its par Status: Completed Start date: Thu Jun 01 00:00:00 GMT-03:00 2017 |
| The pest aphids Sipha flava and Rhopalosiphum padi have caused significant injuries in elephantgrass and brachiaria swards, respectively. Thus, the objective of this project was to evaluate the bioecology of these pest insects and the predator Chrysoperla externa. The biological aspects of the pests were studied at 12, 16, 20, 24, 28 and 32ºC. Temperatures of 20ºC and 24ºC were more favorable for insect development, and this temperature range is the most appropriate for t ...

| The assets of a company have unquestionable value. Thus, their effective management is necessary. This management has been automated, i.e. the agent registers the assets with software and can report on it. However, the movements of goods from one place to another is unavoidable, and thus agents can lose their new location if they are not warned about the displacement. Thus, it is periodically necessary to make a complete survey of the property and then update the database. This project aims to b Status: Completed Start date: Sun Jul 01 00:00:00 GMT-03:00 2007 |
| The state of Pará is responsible for 80% of the national black pepper production, and Brazil is the third biggest producer and exporter of the spice. However, the production and productivity of the culture has been decreasing throughout the years due to the occurrence of the root rotting disease caused by Fusarium solani f sp. Piperis in a great number of black pepper farms, leading to great economical loss and substantial decline in plantation area along the period of more than forty ye ...

| The growing biofuel industry generates by-products that have shown promise as energy and protein feeds in ruminant diets. The objective of this project was to determine the effects of by-products of biodiesel production, obtained from different sources of oilseeds, on the in vitro degradability of nutrients, in vitro ruminal fermentation and methane gas production. Palisadegrass ( Brachiaria brizantha) was used as a model. Its isolated incubation was considered as a contro ... Status: Completed Start date: Wed Aug 01 00:00:00 GMT-03:00 2007 |
| Bananas are one of Brazil's main agricultural products, having great economical significance. With a production reaching over five million tons annually, the fruit is a source of food for millions of people around the world. However, the plantations have been facing diseases and plagues which reduce the productive cycle once the local farmers are oblivious to certain agricultural practices. In the Amazon, the need to increase the crops is hindered by the lack of quality genetic strains for disse Status: Completed Start date: Sun Apr 01 00:00:00 GMT-03:00 2007 |
| 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 |
| 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.
