Nutritional effects of calcium, magnesium, silica and sodium chloride on certain anatomical characters of rice plant related to lodging

Abstract

The anatomical changes induced by the application of elements like Calcium Magnesium, Silica and Sodium chloride and their relationship with lodging resistance were studied in one lodging variety. The study indicates the differential effects of Calcium and Magnesium on the anatomical characters of nee Calcium weakens the straw strength and favours lodging by producing large thin walled cells while Magnesium resist the lodging tendency by producing small but thick and compact cells. Silica and Sodium chloride also, to same extent induce anatomical changes favourable for lodging resistance.
