ABSTRACT Among the efficient strategies to manage plant parasitic nematodes, use of resistant cultivars stands out for being frequently easiest and least expensive approach that can be adopted by farmers. However, common bean, in Brazil, few sources resistance have been identified so far. This study aimed assess reaction 81 bean genotypes most abundant harmful nematode species Brazilian crop fi...

Broadcast plantings of nonhost cultivars (alfalfa, barley, bean, onion, potato, and wheat) in soil in redwood boxes (4.2 x 30 x 14 cm) infested with Heterodera schachtii reduced the initial nematode populations (P = 0.05). The reduction was greater with sugarbeets, a host, than with all other cropping treatments except onion, bean, and fallow (P = 0.05). After 80 days, when the root growth of a...

Common bean is typically cultivated in the Mediterranean basin, an area where water scarcity could limit yield. This species has a broad range of food uses (seed or pod) and very diverse growth patterns (indeterminate determinate), which hinders any deficit irrigation strategy. The aim this work was to evaluate response vegetative reproductive stages stress beans indeterminate habit. During two...

Background The use of desiccant herbicides can allow the anticipation common bean harvesting by providing a reduction in humidity plants and grains. Objective Determine effect doses on moisture content (stems, leaves grains), 100 grains mass, grain yield physiological quality seeds two contrasting cultivars. Methods experimental design for each cultivar (BRS FC 104, super early cycle, 60 days [...
