  abstract = {{V}illage irrigation schemes cover about 25% of the irrigated area on the two banks of the {S}enegal {R}iver. {W}e analyzed irrigation scheme and rice crop management practices during the 1998 wet season in this type of irrigation scheme in {M}auritania. {A}verage yield was 4.8 t ha(-1); problems with irrigation rules resulted in great variability of irrigation frequency between fields, and sub-optimal timing of nitrogen fertilizer application resulted in yield losses. {B}ased on this diagnosis, we suggested to farmers new irrigation rules and cropping calendars planned on the scale of the irrigation scheme. {P}lanned cropping calendars were built using {C}al{C}ul, a software that we designed on the basis of the irrigated rice development model {RIDEV}. {T}hese suggestions of improved collective management were implemented in the 1999 and 2000 wet seasons. {A}verage yield reached 7.2 t ha(-1) in 1999 and 8.2 t ha(-1) in 2000, without any significant increase in production costs. {T}his great increase in rice productivity was mainly due to better collective management obtained through planning cropping calendars. {T}his result showed that technical innovation is not the only way to improve productivity.},
