ABSTRACT
An experiment was carried out under field conditions to determine the impact of silicon application with different concentrations(20, 40, 60 ppm), on selected physiological characteristics of the leaves of mungbean (Vignaradiata) and cowpea (Vignaunguiculata) under different 100%, 75%, 50% and 25% soil moisture regimes. Stock solution (100 ppm) of silicon was preparedby MgSi3 salt but apply as 20, 40, 60 ppm solution in both treated and control plants. Results showed that silicon applicationsignificantly increases total carbohydrate & protein contents in treated samples as compare to control plants. In present study weconcluded that silicon promoted growth in the drought susceptible species to greater extent & it’s more beneficial forcarbohydrates and protein metabolism of cowpea (Vigna unguiculata) as compare to mungbean (Vignaradiata) plants.
