Última Gas exchange in massai grass under five nitrogen fertilization levels during establishment and regrowth R. Bras. Zootec. Lopes,Marcos Neves; Lacerda,Claudivan Feitosa de; Cândido,Magno José Duarte; Pompeu,Roberto Cláudio Fernandes Franco; Silva,Rodrigo Gregório da; Lopes,José Wellington Batista; Fernandes,Francisco Ronaldo Belém; Bezerra,Francisco Marcus Lima. The objective of this study was to evaluate gas exchange in the massai grass during establishment and regrowth cycles in a greenhouse, using five nitrogen (N) fertilization levels. A completely randomized split-plot design of five nitrogen levels (0; 150; 300; 450 and 600 mg N•dm-3 of soil) was employed with the N levels as plots, and the cycles (establishment, regrowth 1 and 2) as subplots, evaluated with five replicates. We evaluated leaf transpiration (E), leaf temperature (TFOL), leaf photosynthesis rate (A), leaf carbon dioxide concentration (Ci), stomatal conductance (gs), photosynthesis/transpiration ratio (A/E), photosynthesis/conductance ratio (A/gs), chlorophyll relative index (CRI), and nitrogen sufficiency index (NSI). Growth cycles influenced... Tipo: Info:eu-repo/semantics/article Palavras-chave: Chlorophyll; CO2 concentration; Panicum maximum; Photosynthesis.

Almeida,Wener Santos de; Fernandes,Francisco Ronaldo Belém; Teófilo,Elizita Maria; Bertini,Cândida Hermínia Campos de Magalhães. This study aimed at verifying the effect of genotype x environment interaction on the relative contribution of yield components and final production of different cowpea genotypes. For this, data of yield components of 22 cowpea genotypes were evaluated in four environments in the State of Ceará. A one-way ANOVA tested the variability between genotypes and the Scott-Knott test compared the mean values of the genotypes. The correlations were estimated by a path analysis. A differentiated response from the genotypes to each environment was observed for all traits examined, indicating the need to perform the test for each situation separately. The number of pods per plant is the yield component with great potential of genetic gain in additional cycles of...
