Agriculture in Benin mainly rainfed has experienced a disruption in relation to the agricultural calendar due to the effects of climate variability. The objective of this work is to contribute to the improvement of cotton yield by an appropriate choice of the sowing period in the Municipality of Banikoara. To achieve this, climatic data covering the period from 1981 to 2015 were collected and processed using different software (Excel spreadsheet, Khronostat).It emerges from this work that there is a strong variation in rains and temperatures during the period 1981 to 2015 with a downward trend in the rainy season. Thus, the favorable periods for cotton cultivation are those where the start of the cycle is between the periods of June 10 to 30. Regarding the sowing date of June 15, a significant yield of 1987.5 kg / ha was recorded. At the same date, a significant improvement in the phenological parameters was observed, the largest size of the cotton plant being estimated at 67.25 cm and the diameter of the pod is 2.85 cm.As a result, improving cotton yield in the study area must go through the reorganization of the cropping calendar.

Abstract: (french)
L’agriculture au Bénin essentiellement pluviale a connu une perturbation par rapport au calendrier agricole en raison des effets de la variabilité climatique. L’objectif visé par le présent travail est de contribuer à l’amélioration du rendement du cotonnier par un choix approprié de la période de semis dans la Commune de Banikoara. Pour y parvenir, les données climatiques couvrant la période de 1981 à 2015 ont été collectées et traitées à l’aide de différents logiciels (Tableur Excel, Khronostat).Il ressort de ces travaux qu’il y a une forte variation des pluies et des températures durant la période 1981 à 2015 avec une tendance à la baisse de la saison pluvieuse. Ainsi, les périodes favorables à la culture du cotonnier sont celles dont le début du cycle est compris entre la période du 10 au 30 juin. En ce qui concerne la date de semis du 15 juin, il a été enregistré un rendement important de 1987,5 kg/ha. A la même date, il a été observé une amélioration importante des paramètres phénologiques dont la taille la plus importante du pied du cotonnier est estimée à 67,25 cm et le diamètre de la gousse est de 2,85 cm.Il en résulte que l’amélioration du rendement du cotonnier dans la zone d’étude doit passer par la réorganisation du calendrier cultural.
