LES EFFETS DU STADE, DE LA HAUTEUR D’ECIMAGE ET DE LA DISTANCE DE PLANTATION SUR LA PRODUCTION DU TABAC A CIGARE

Abstract

The effects of planting distance, topping stage and topping height on the agronomic characteristics and chemical composition of cigar filler tobacco were observed during a 4-yr period. Plants were spaced 41 or 51 cm in the row and topped at the bud, early bloom or full bloom stage; topping height was normal or high. Plant spacing of 41 cm and high topping at early bloom gave maximum yield. Tobacco quality, gross return, percent marketable tobacco, percent filler, nicotine and total alkaloids were decreased by topping at either early or full bloom, high topping or by increased planting distance in the row.
