Acumulación de materia seca y micronutrimentos de dos cultivares de yuca (Manihot esculenta Crantz)

This paper deals with the results obtained in the determination of dry matter and macronutrients in cassava setts in several periods of the life cycle of the plant. It was shown that setts had a three fold increase in dry matter till the end of the life cycle; accumulation started with the beginning...
