Calcium Silicate was used for the trials
Two legume plant species, cowpea and kidney bean, were grown in a glasshouse in a hydroponics system where salt (NaCl) was added to the solutions
- The results showed that “for both species, salinity reduced all growth variables but the silicon amendment partly overcame the reduction in growth. Addition of silicon in NaCl stressed plants maintained membrane permeability”
- “Potassium concentration was reduced in all salt treatments but increased in both species in salt treated plants in the presence of silicon”
- The results suggest that “in hydroponically grown cowpea and kidney bean crops, the inclusion of silicon in the nutrient solution is beneficial because it improves the growth, the physiological characteristics and may contribute to a more balanced nutrition by enhancing the nutrient uptake under salt stressed conditions”
