Effet de l’apport au sol de déchets issus de l’égrenage du coton graine sur l’humidité du sol et la production en coton graine au nord de la Côte d’Ivoire

Abstract

Objectif : Pour tenter de réduire les effets de ces changements climatiques sur les productions, un apport au sol avant les mises en place des cultures de 12 t/ha de déchets de coton graine ou de compost associé à la moitié de la dose d’engrais minéral recommandée (200 kg/ha de NPK + 50 kg/ha d’urée) a permis d’améliorer l’humidité du sol sans aucun effet sur l’eau utile du sol. L’apport de déchets de coton graine ou de compost a permis aussi d’améliorer le nombre de capsules par plante, le nombre de capsules mûres récoltées, la qualité sanitaire des capsules mûres et surtout le rendement en coton graine. Conclusion : L’apport de 12 tonnes/ha de déchets de coton graine associés à de l’engrais chimique à la dose de 100 kg/ha de NPK et 25 kg/ha d’urée constituent un niveau optimum d’utilisation des déchets de coton graine en coton culture. Mots clés : Déchets de Coton graine, Humidité du sol, Rendement du cotonnier, Côte d’Ivoire. Effect of ginned cotton-seed waste application to the ground on soil moisture and cotton yield in northern Côte d'Ivoire ABSTRACT Objective: In an attempt to reduce the effects of climate change on production, an application to the ground prior to the establishment of 12 t/ha of ginned seed cotton waste associated with half of the recommended mineral fertilizer dose (200 kg/ha of NPK + 50 kg/ha of urea) improved soil moisture without any effect on the soil available water capacity. The supply of seed cotton waste or compost has also improved the number of capsules/plant, the number of mature capsules harvested, the sanitary quality of mature capsules and, above all, the yield in seed cotton. Conclusion: The supply of 12 tons/ha of seed cotton waste associated with chemical fertilizer at the dose of 100 kg/ha of NPK and 25 kg/ha of urea constitutes an optimum level of use of cotton seed waste in cotton farming. Keywords: Seed Cotton Waste, Soil Moisture, Cotton Yield, Ivory Coast.
