Heterogeneity between centers in multicenter trials with time to event outcome can be modeled by the frailty proportional hazards model. The majority of the different approaches that have been used to fit frailty models assume either the gamma or the lognormal frailty density and are based on sim...

Three phases of Rhizobium inoculation trials were carried out as part of a programme to select forage legume germplasm adapted to acid, infertile Oxisols of tropical America. Firstly, a range of tropical forage legumes were evaluated for their response to N fertilization or inoculation with strai...

En el invernadero se evaluó la efectividad de las cepas preseleccionadas de B. japonicum (CIAT 199,209,3778,3874 y 3876) de la recomendada (CIAT51) y una de Rhizobium spp (CIAT 3779). En el suelo Fluventic Haplustoll, de reacción casi neutra, se presentó respuesta altamente significativa a la ino...

Four inoculated ecotypes of each of Centrosema acutifolium, C. brasilianum and C. macrocarpum were grown in undisturbed soil (oxisol) cores in a glasshouse to study their response to 7 phosporus levels (a total of 11, 22, 45, 90, 180, 360 and 720 mg/core P, surface applied as Ca(H2PO4)2.H2O).

Ten isolates of Bradyrhizobium spp. which form two colony types were studied; the isolates originated from a range of legume species. The two colony types differed in the amount of gum formed or size or both, depending on the strain. Whole 7-day-old colonies of each type were subcultured to deter...
