| Abstract | Au Burkina Faso, le recyclage des résidus de culture constitue un défi pour l’amélioration de la productivité des systèmes de production agricole. L’objectif de cette étude était d’évaluer les effets de la gestion des résidus du bananier (Musa acuminata C.) et de la fumure minérale sur les caractéristiques chimiques du sol et le rendement du maïs (Zea mays L.). Un essai en split-plot avec quatre répétitions comparant quatre modes de gestion des résidus du bananier et quatre options de fumure minérale a été conduit en culture pluviale et en culture irriguée. Les rendements grains du maïs ont augmenté de 24 à 66,2% avec le paillage et l’enfouissement de résidus par rapport au brûlage et au ramassage. Le pH, le carbone total, l’azote total et le potassium disponible du sol ont été améliorés par le paillage, l’enfouissement et le brûlage des résidus comparativement au ramassage. L’utilisation combinée des résidus et des engrais a permis un accroissement significatif des rendements. Cependant, elle a induit une baisse du pH et du potassium total du sol comparativement au témoin. L’étude a montré l’intérêt du paillage et de l’enfouissement des résidus du bananier combiné avec la fumure azotée pour améliorer les rendements de maïs. English title: The effects of banana tree residues managements and mineral fertilizers use options on soil chemical properties and maize yield in a banana tree / maize rotation system in western Burkina Faso In Burkina Faso, the recycling of crop residues for improving the productivity of cropping systems is still a challenge. The aim of this study was to evaluate the effects of the management of banana tree (Musa acuminata C.) residues and mineral fertilizers on both soil chemical characteristics and the yield of maize (Zea mays L.). A split-plot trial with four repetitions comparing four management types of banana tree residues (mulching, burying, burning and exporting) and four application options of mineral fertilizers was conducted in rain-fed and irrigated cropping systems. The results revealed that the maize grain yield increased by 24 to 66.2% with mulching and burying residues (green manure) compared to burning or exporting the banana tree residues. Soil pH, total carbon and nitrogen as well as available potassium were improved by the mulching, burying and burning compared to exporting the banana tree residues. The combined use of the residues and mineral fertilizers significantly improved the maize yield. However, it caused a decrease in the soil pH and total potassium compared to the control treatment. The study demonstrated that mulching and burying banana tree residues in combination with mineral fertilizer improves maize yield. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
