Growth of Sugar Beet (Var. Polyrave) in Relation to Petiole Nitrate Content

Abstract

SUMMARYNitrate content in the petiole of sugar beet (var. Polygrave) reaches its maximum three months after emergence of the seedling. There is a linear correlation between the final yields and the nitrate content of the petiole at the maximum stage. Nitrogen fertilization should be given in the first three months of the beet growth.
