The use of phosphite as a fungicide or supplementary source of phosphorus (P) has been intensified in recent years, however, little is known about its effects on important crops such as common bean. This work aimed to evaluate the effect of phosphite on growth and phosphate nutrition of bean plants. Two experiments in an completely randomized design were conducted in nutrient solution in a green house, from January to March 2008. In the first experiment, the treatments consisted of a […]

In recent years, physic nut (Jatropha curcas L.) has attracted attention because of its potential for biofuel production. Although it is adapted to low-fertility soils, physic nut requires soil acidity corrections and addition of a considerable amount of fertilizer for high productivity. The objective of this research was to evaluate the effectiveness of arbuscular mycorrhizal fungi (AMF) (control without AMF inoculation, Gigaspora margarita inoculation or Glomus clarum inoculation) on increasing growth and yield of physic nut seedlings under different rates […]
