Silicon supplied via foliar application and root to attenuate potassium deficiency in common bean plants

Abstract Potassium (K) deficiency affects physiological performance and decreases vegetative growth in common bean plants. Although silicon (Si) supplied via nutrient solution or foliar application may alleviate nutritional stress, research on the bean crop is incipient. Thus, two experiments were c...
