This research was carried out on the rice farming sites of the agronomic research substation of Finkolo in the sudan-Guinean zone of Mali. The objective was to test the efficiency of the application of some dosage of mineral manure in the production of rain rice. Specifically the study aimed to evaluate the effect of different dosages in the use or the cereal complex and of urea within the agronomic parameters of rice varieties (NERICA 4 and 8). The experimental setup used was a bloc factorial conducted three times. The dosage of 100 and 200 kg ha-1 of the cereal complex to the best performance on the whole parameters measured of the rice. Moreover, the growth in hight and the straw yiel were better due to the application of 100 and 150 Kg ha-1 of urea. The Nerica 8 was more performant in paddy yield compared to Nerica 4. The application of mineral manure should be recommanded in rain rice farming in order to improve the production in the ameliorated varieties because it enhances noticeably the yield. In order to obtain a better efficiency in the use of the mineral manure, above all the nitrogen fertilizer, a suited localisation for the application is required.

Abstract: (french)
Cette étude a été réalisée sur les parcelles rizicoles de la sous-station de recherche agronomique de Finkolo en zone soudano-guinéenne du Mali. Elle avait pour objectif d’examiner l’efficacité de l’application des doses de fumure minérale pour la production du riz pluvial. De façon spécifique, l’étude visait à évaluer l’effet de différentes doses d’application du complexe céréale et de l’urée sur les paramètres agronomiques des variétés de riz (NERICA 4 et 8). Le dispositif expérimental utilisé était un factoriel en bloc à trois répétitions. Les doses de 100 et 200 kg ha-1 de complexe céréale ont induit les meilleures performances chez le riz. De plus, la croissance en hauteur et le rendement paille ont été meilleurs suite à l’application des doses de 100 et 150 kg ha-1 d’urée. La variété NERICA 8 a été beaucoup plus performante pour le paramètre rendement paddy comparativement à la variété NERICA 4. L’utilisation de la fumure minérale doit être recommandée en riziculture pluviale pour améliorer la productivité des variétés améliorées car elle augmente nettement les rendements. Pour une meilleure efficacité de la fumure minérale, surtout la fumure azotée, l’étude a suggéré la localisation et l’enfouissement des engrais.
