Heavy metals in cowpea (Vigna unguiculata L.) after tannery sludge compost amendment
(Inst Investigaciones Agropecuarias, 2013-07-01)
Repeated soil amendment with industrial waste can affect the accumulation of chemical elements, mainly heavy metals, in plants. We therefore evaluated the accumulation of Cr, Cd, Ni, and Pb in cowpea (Vigna unguiculata ...
Heavy metals and yield of cowpea cultivated under composted tannery sludge amendment
(Editora da Universidade Estadual de Maringá - EDUEM, 2014-12-01)
The study aimed to evaluate the phytoavailability of heavy metals (Cr, Cd, Ni and Pb) concentrations in leaves and grains, and yield of cowpea (Vigna unguiculata L) grown in soil amended with composted tannery sludge (CTS) ...
Tolerância e caracterização bioquímica em feijão-caupi submetido a estresse hídrico na pré-floração
(2010)
This research study aimed to evaluate the biochemical parameters of drought tolerance in cowpea (Vigna unguiculata (L.) Walp) genotypes under irrigation with and without water stress at pre-flowering growth stage. Thus, ...

(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 2013-09-01)
The objective of this work was to characterize the resistance of 50 cowpea (Vigna unguiculata) genotypes to Callosobruchus maculatus. A completely randomized design with five replicates per treatment (genotype) was used. ...
Preliminary study of a methodology based on the degree-days concept for predicting the phenological phases of crops
(Fundacion Romulo Raggio, 1997-01-01)
This work develops a methodology (using the degree-days concept and linear regression), to forecast the duration of phenological phases in crops. An experiment was conducted in the greenhouse with three cultivars of cowpea ...
