Download or read book Les Techniques de Labour Et la Pr paration Du Sol en C r aliculture written by Tahar Mansouri and published by Omniscriptum. This book was released on 2011-02 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les techniques culturales en céréaliculture au Nord-Ouest de la Tunisie sont confrontées à des contraintes de climat et de nature du sol et rencontrent des problèmes technique, énergétique et agro-pédologique. Cette spécificité a des effets sur la préparation du sol et le semis et sur la structure du sol et influence le rendement de la culture et le prix des céréales. L'introduction de nouvelles techniques de travail du sol permet l'amélioration de la production, l'économie d'énergie et la conservation de la structure du sol. Le travail combiné réduit la consommation d'énergie de 18 à 48% par rapport aux itinéraires du chisel et de 34 à 50% par rapport aux itinéraires de la charrue. Le temps de labour de la charrue dépasse le chisel de 39 à 51% et le travail combiné de 79 à 87%. La traction du chisel nécessite moins d'effort que la charrue de 28 à 65%. La régression de l'effort de traction est en relation avec la vitesse, la profondeur du labour et l'état physique du sol. Les variables physiques du sol et agronomiques montrent que le combiné de la charrue ou du chisel entraîne des profils homogènes, améliore les conditions du sol et engendre un rendement cultural meilleur.
