Food problem and availability of fodder are real development’s brakes of breeding in Sahel. The aim of study is to determine productivity of alfalfa grown in rainy season. It was carried out on experimental site of Faculty of Agronomy in Abdou Moumouni University (Niamey). Experimental set-up consists of 8 plots of 3m x 2m with inter-plot spacing of 1 m. A spacing of 20 cm by 20 cm was used when sowing. Water was added when needed and 100 kg NPK per hectare was added after first cut. An emergence rate of 15.52% was obtained respectively, number of branches reached 4 ± 2 branches at 1st cut. Height of plants was 41.33 ± 10.31 cm 45 days after sowing; 41.67 ± 9.79 cm at 2nd cut in 20 days and 29.5 ± 7.63 cm at 3rd cut in 20 days. The yield (kg DM / ha) at first cut is 510.7 kg. At second cut, it is 1394.95 kg and the third cut yield is 944.42 kg. The average production in 85 days is 2850.07 kg DM / ha. This culture is promising, given conditions and means used during trial. It can produce better when put in best conditions.

Abstract: (french)
Le problème alimentaire et du disponible fourrager constituent les véritables freins au développement de l’élevage au Sahel. L’étude a pour but de déterminer la productivité de la luzerne cultivée en saison pluvieuse. Elle a été réalisée sur le site expérimental de la Faculté d’Agronomie de l’Université Abdou Moumouni (Niamey). Le dispositif expérimental est constitué de 8 parcelles de 3m x 2m avec des espacements inter-parcelles de 1 m. Un écartement de 20 cm sur 20 cm était utilisé lors du semis. Un apport d’eau est apporté en cas de besoin et un apport de 100 kg de NPK à l’hectare est fait après la première coupe. Un taux de levée de 15,52% est obtenu. Le nombre de rameaux a atteint 4 ± 2 à la 1ère coupe et la hauteur des plants est de 41,33 ± 10,31 cm 45 jours après semis; 41,67 ± 9,79 cm à la 2ème coupe en 20 jours et 29,5 ± 7,63 cm à la 3ème coupe en 20 jours. Le rendement (kg MS/ha) à la première coupe est de 510,7 kg. A la deuxième, il est de 1394,95 kg. Pour la troisième coupe, il est de 944,42 kg. La production moyenne en 85 jours est 2850,07 kg MS/ha. Cette culture est prometteuse, vue les conditions de réalisation de cet essai. Elle peut mieux produire lorsqu’elle est cultivée dans des conditions meilleures.
