Cette étude a été conduite sur le sorgho fourrager multicoupe en période de forte chaleur au Niger. Le dispositif expérimental adopté est un dispositif en randomisation totale, une affectation au hasard des différents traitements aux différentes unités expérimentales avec un facteur (régimes d'irrigation) et deux niveaux (traitement 1 une irrigation chaque trois (3) jours et traitement 2 une irrigation chaque six (6) jours) et trois (3) répétitions. La germination a commencé 3 jours après le semis et a pris fin 5 jours après le semis avec un taux de germination moyen dépassant les 98% des poquets. A la première coupe, la production fourragère était de 26,16 tonnes de matières sèches par hectare pour le traitement 1 contre 17,92 tonnes de matières sèches par hectare pour les parcelles du traitement 2........
