Effect of Exogenous Application of Silicon with Drought Stress on Protein and Carbohydrate Contents of Edible Beans (Vigna radiate & Vigna unguiculata)

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 (Vigna unguiculata) under different 100%, 75%, 50% and 25% soil moisture regimes. Stock solution (100 ppm) of silicon was prepared by MgSi₃ salt but apply as 20, 40, 60 ppm solution in both treated and control plants. Results showed that silicon application significantly increases total carbohydrate & protein contents in treated samples as compare to control plants. In present study we concluded that silicon promoted growth in the drought susceptible species to greater extent & it’s more beneficial for carbohydrates and protein metabolism of cowpea (Vigna unguiculata) as compare to mungbean (Vignaradiata) plants.
