A Sahelian country, Niger has an arid climate. Socioeconomic development is essentially based on agriculture. This activity employs more than 80% of the working population in rural areas. Unfortunately, it is hampered by the scarcity and irregularity of water leading to a drop in crop yields and a risk of food insecurity. In this context, irrigation has established itself as an essential path for the sustainable development of agriculture in Niger. The objective of this study is the tensiometric monitoring of the evolution of soil water reserve. To achieve this objective, a device aimed at determining the reading on the tensiometer from which it is necessary to trigger the irrigation so that the crop does not suffer from water deficit, is installed on a clayey-sandy soil in the market gardening site of Birni N'Konni. The results led to the conclusion that the water supply is renewed each time the voltages observed are between 16 and 22 centibars. It should be noted that 24 hours after adding water, the voltages are between 05 and 06 centibars.

In this context, irrigation has established itself as an essential path for the sustainable development of agriculture in Niger. The objective of this study is the tensiometric monitoring of the evolution of soil water reserve.

Abstract: (french)
Pays sahélien, le Niger a un climat aride. Le développement socioéconomique est essentiellement basé sur l’agriculture. Cette activité emploie plus de 80 % de la population active dans les zones rurales. Malheureusement, elle est entravée par la rareté et l’irrégularité des eaux entrainant une baisse des rendements des cultures et un risque d'insécurité alimentaire. Dans ce contexte, l’irrigation s’est imposée comme une voie incontournable pour le développement durable de l’agriculture au Niger. L'objectif de cette étude est le suivi tensiométrique de l’évolution de réserve en eau du sol. Pour atteindre cet objectif, un dispositif visant à déterminer la lecture sur le tensiomètre à partir de laquelle on déclenche l’irrigation pour que la culture ne subisse pas de déficit hydrique, est installé sur un sol argilo-sableux dans le site maraicher de Birni N’Konni. Les résultats ont permis de conclure que l’apport d’eau est renouvelé chaque fois que les tensions observées sont entre 16 et 22 centibars. Il est à noter que 24 heures après apport d’eau les tensions se situent entre 05 et 06 centibars.
