Teor de clorofila, exportação de nutrientes e desempenho agronômico de híbridos...
Zandonadi, César Henrique SouzaSorghum is an extremely important crop for the second season, particularly in Brazilian savannah. Information about the development of the crop in different sowing dates, prompt and accurate fertilizer management and use of adapted cultivars are important for making decision by farmers. Thus, studies were conducted to evaluate the productive performance and concentration of nutrients in grain sorghum hybrids in...
Fitotoxicidade causada por deriva simulada dos herbicidas chlorimuron ethyl e t...
Borges, MarcelaConselho Nacional de Desenvolvimento Científico e Tecnológico; Potato development (Solanum tuberosum subs. tuberosum) is affected by a large number of factors, both biotic and abiotic, that can influence its growth, development and productivity. Considering that many potato production areas are located close to other crops, such as maize and soybeans, the use of herbicides in these crops can affect potatoes thr...
Épocas de aplicação do espiromesifeno no controle de brevipalpus phoenicis (gei...
Costa, Thaís Ribeiro daFrom the factors that affect the coffee production, the damages caused by the mite Brevipalpus phoenicis (GEIJSKES) have a significant economical expressiveness and, its importance on this plant culture happens due to the vector of the ringspot virus, responsible for the leaf fall and for the reduction of the coffee quality. The recommended season for the chemical control of this mite is after the harvest, when...
Detecção de Sclerotinia sclerotiorum em meio Neon-S modificado em sementes de s...
Santos, Roberto Resende dosThe Neon-S method has been used for the detection of Sclerotinia sclerotiorum in soybean and common beans since the agricultural year 2010. However, this method yields false positive readings due to other fungi that change medium pH. Thus, this study evaluated the contribution of increasing incubation period on the optimization of Neon-S reliability in different cultivars of soybeans and common beans. Nine trea...
Micro-organismos, quitina e quitosana no manejo de nematoides das galhas no tom...
Mota, Lara Caroline Borges MoreiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Among the forms of plant-parasitic nematode management, biological control with soil microorganisms and the induction of resistance stand out. This study evaluated the effectiveness of microorganisms, chitin and chitosan in the management of root-knot nematodes on tomato. Three experiments were done to confirm such effectiveness. The first experiment ...
Estabelecimento e desenvolvimento inicial de Barueiro (Dipteryx alata vog.) in ...
Silva, Herick Fernando de JesusConselho Nacional de Desenvolvimento Científico e Tecnológico; The barueiro (Dipteryx alata Vog.) is a fruit crop of the Cerrado of great importance in food and feed, the recovery of degraded areas and landscaping. It is set in an environment where natural devastation promoted by human activities puts you at risk of extinction. Thus aimed to evaluate this work the in vitro establishment of D. alata through the ...
Características agronômicas do sorgo e eucalipto em diferentes arranjos espaciais
Clemente, Marina AlvesAgriculture and cattle raising expansion into new areas to supply the demand for food has become unviable. Moreover, the increasing presence of degraded pastures shows the need to revert such situation. Thus, integration of crop production with cattle rising and forestry (iLPF) becomes a new standard, allowing the renovation of areas in degradation process while, at the same time, allows the production of food ...
Eficiência agronômica de fontes alternativas de fósforo
Nicchio, BrunoCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Brazil has an important role in the production of phosphorus (P) sources since phosphate minerals are finite. Moreover, the raw materials for the production of phosphate fertilizers present low quality, demanding the use of technologies that can turn fertilizers more expensive; however, there are some options to reduce this cost, making viable the use...
Sensibilidade de teca (Tectonas grandis L. f.) a matocompetição e a herbicidas
Domingos Júnior, Fausto AntônioInvasive plants have been a limiting factor for the initial establishment of planted forests, especially when that occurs over degraded grazing areas with Brachiaria spp. Two studies were done to determine the impact of weeds, and its control, on teak establishment. The first one evaluated teak growth under the influence of Brachiaria decumbens. Treatments were no weed control, complete control of weeds, weed c...
Ocorrência de Pasteuria sp. em Heterodera glycines no Brasil e compatibilidade ...
Lovato, Bruno VenturaSoybean cyst nematode, Heterodera glycines, can be found in up to 2 million hectares in Brazil. Few agronomic practices are economically suitable and effective against this nematode, therefore new tools development becomes important. The objective of this study was assessing the natural occurrence of Pasteuria sp. on H. glycines populations; P. nishizawae, PN1 isolated, endospores attachment on different H. gly...
