Metalaxyl effect on nitrogenase activity (acetylene reduction) and yield of mungbean (Vigna radiata (L.) wilzek). Journal of Environmental Biology. 2001 Apr; 22(2): 79-81http://imsear.searo.who.int/handle/123456789/113845In an experiment, application of different levels of metalaxyl to a sandy loam soil significantly affected the nodulation and nitrogenase activity of mungbean. In both the compost amended and unamended soils, 0.5 mg kg(-1) of metalaxyl enhanced acetylene reduction activity and yield of mungbean, where as higher concentrations (1 mg and 2.5 mg kg(-1) of fungicide) inhibited the nodulation traits as well as economic traits of mungbean.engAcetylene --metabolismAlanine --adverse effectsBradyrhizobiumFabaceae --drug effectsFungicides, Industrial --adverse effectsNitrogenase --drug effectsPlant Roots --microbiologyJournal Article
