Diagnóstico da agricultura de precisão no sudoeste do estado de Goiás
Soares Filho, RomeuThe precision agriculture (PA), initiated in Brazil at the end of the last century is considered as the newest management tool of agricultural activity, also has in Brazilian Savanna soils, where soil and climate conditions are favorable to the development of cultures, a perfect field for its development. There are, however, in the region lack of information about the State of the art of this new technique, alr...
Palhada de cana-de-açúcar em condição de cerrado : decomposição e disponibilida...
Benedetti, Marcelo MunizConselho Nacional de Desenvolvimento Científico e Tecnológico; Nowadays there are many discussions about the potential effects of sugarcane trash prevenient from the ending of farming burnings or post-harvest accumulation in the sugar cane growth. The sugarcane firing based harvest system without previous trash removal is a practice which promotes a new nutrient cycling dynamics, soil structuration, and also po...
Proteção e nutrição foliar na produção de massa seca, acúmulo, extração e expor...
Faria, Marcos Vieira deCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Corn is a very important crop in Brazil and worldwide and, to increase dry matter production, and nutrient accumulation, extraction and exportation, a balanced nutrition and leaf protection should be done keeping them active up to the end of the crop cycle, in order to allow the processing of absorbed nutrients and photo-assimilates distribution. Thus...
Propagação in vitro da gabirobeira (Campomanesia spp.)
Maldonado, Alirio Coromoto DaboinCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Gabirobeira is a typical fruit from the Brazilian Savannah presenting social, economic and commercial importance; however, its preservation is threatened by the expansion of agriculture and by predatory extractivism. This study proposes a protocol for in vitro propagation of the species. Several experiments were done from 2010 to 2013, using fruits ha...
Cama de frango e organomineral na cultura da cana-de-açúcar
Ramos, Lucélia AlvesFundação de Amparo a Pesquisa do Estado de Minas Gerais; Sugarcane fertilization takes a fundamental role in the whole production process, affecting the crop directly and indirectly. The use of organic residues as nutrient sources can be an alternative for substituting or complementing mineral fertilization for the crop. Therefore, this study determined the effect of poultry litter, organomineral and mineral fe...
Sistemas agrícolas e adubação na biomassa e óleo essencial de lavanda (Lavandul...
Silva, Sérgio MacedoFundação de Amparo a Pesquisa do Estado de Minas Gerais; Lavender is grown commercially for the production of essential oil to obtain various products of perfumery and aromatherapy. In the case of aromatic species, the presence of oxygenated monoterpenes can ensure medicinal properties and therapeutic effects of essential oils. On the other hand, the content and the chemical composition of essential oil depends...
Aspectos germinativos de 25 espécies florestais brasileiras: eficiência do méto...
Anastácio, Maristela RosáliaCHAPTER II: The Rules for Seed Analysis determine mandatory methods for Analysis Laboratories Seeds accredited by the Ministry of Agriculture, Livestock and Supply. However, there are few validated methods available for forest species in this manual. For this reason, doubts about the conduct tests of these seeds are constant, especially, those related to the type of substrate, sterilization, temperature, pre-ge...
Ocorrência de Pasteuria nishizawae em áreas de soja e controle de Heterodera gl...
Vicente, Camilla BuiattiSoybean (Glycine max (L.) Merrill) is a crop of great economic importance. Brazil is the second largest producer and exporter. One of the most serious disease problems of this culture is the cyst nematode Heterodera glycines (Ichinohe), considered as its most destructive parasite. The first occurrence of this disease in Brazil was reported in the 1991/1992 harvest. Nematode control is more difficult than that o...
Fertilizante organomineral em batata, cv. Atlantic: produtividade, crescimento ...
Cardoso, Atalita FrancisPotato is a vegetable of great economic importance, presenting high rates of fertilizer application. Therefore, there is a need to find alternatives that may minimize costs while favoring nutrient cycling. Organomineral fertilizers affect positively soil physical, chemical and biological characteristics, improving water and cation retention, aeration, porosity and the proliferation of microorganisms. Residues t...
Dinâmica da água em diásporos de espécies de interesse agrícola
Oliveira, João Paulo Ribeiro deFundação de Amparo a Pesquisa do Estado de Minas Gerais; Consecrated as imbibition curve, the dynamics of water absorption demonstrates diaspore germination in a reliable way. Nevertheless, this event still is little explored and even neglected. Moreover, if the dynamics of water demonstrates the germination of a diaspore, wouldn\'t it be interesting to measure it? Before even thinking about measuring this proc...
