Absorption curves - mineral-extraction under an aeroponic system for white chrysanthemum (Dendranthema grandiflorum (Ramat.) Kitam. cv. Atlantis White)
Provedor de dados: Acta Agronómica
Autores: Chica Toro,Faber de Jesús; Garzón-González,Jorge M.
Abstract The aim of this study focused on the construction of the absorption and extraction curves under an aeroponic system for White chrysanthemum cv. Atlantis White, and therefore, propose the periods of maximum and minimum nutrient accumulation from aboveground, root and total biomass. Vegetative cycle of the plant, measured from the day after transplantation (dat) to aeroponic system, and the first day of court lasted 49 days. Evaluations were carried out each week on plants, in absolute competition. For the average aboveground biomass, three replicates were recorded. To obtain total root biomass only one sample, was measured. Therefore, total biomass in average, had achieved 130.9313 g.plant-1, where 72.26% (94.163 g) corresponded to the aboveground...

Caracterizacao de varzeas na regiao dos cerrados.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: RASSINI, J. B.; REIS, A. E. G. dos; MACEDO, J.; LEITE, J. C.
A ocorrencia de varzeas na regiao dos Cerrados e grande, com cerca de 12 milhoes de hectares em sua maioria ainda nao utilizadas, devido, principalmente, a baixa disponibilidade de informacao a respeito do sistema solo-agua-planta. O trabalho busca fornecer uma caracterizao e a distribuicao desse tipo de ecossistema nas principais bacias hidrograficas dos Cerrados, apresentando resultados referentes a vegetacao e aos tipos de solo predominantes nessas formacoes.

Critical values of nitrogen indices in tomato plants grown in soil and nutrient solution determined by different statistical procedures
Provedor de dados: Pesquisa Agropecuária Brasileira
Autores: Fontes,Paulo Cezar Rezende; Ronchi,Cláudio Pagotto.
The objective of this study was to establish critical values of the N indices, namely soil-plant analysis development (SPAD), petiole sap N-NO3 and organic N in the tomato leaf adjacent to the first cluster (LAC), under soil and nutrient solution conditions, determined by different statistical approaches. Two experiments were conducted in randomized complete block design with four repli-cations. Tomato plants were grown in soil, in 3 L pot, with five N rates (0, 100, 200, 400 and 800 mg kg-1) and in solution at N rates of 0, 4, 8, 12 and 16 mmol L-1. Experiments in nutrient solution and soil were finished at thirty seven and forty two days after transplanting, respectively. At those times, SPAD index and petiole sap N-NO3 were evaluated in the LAC. Then,...

Physiological responses of maize and cowpea to intercropping
Provedor de dados: Pesquisa Agropecuária Brasileira
Autores: LIMA FILHO,JOSÉ MOACIR PINHEIRO.
The effect of intercropping on plant water status, gas exchange and productivity of maize (Zea mays L.) cv. Centralmex, and cowpea (Vigna unguiculata L. (Walp)) cv. Pitiuba were evaluated under semi-arid conditions at the Embrapa-Centro de Pesquisa Agropecuária do Trópico Semi-Árido (CPATSA) at Petrolina, PE, Brazil. The treatments were: maize and cowpea as sole crops, at a population of 40,000 plants ha-1, and intercropped at a population of 20,000 plants ha-1. The results obtained in this paper appear to be related to the degree of competition experienced by the components, mainly for water and light. Maize intercropped had higher values of leaf water potential, stomatal conductance, transpiration and photosynthesis than as sole crop. Intercropped cowpea...
