L'impact de la péjoration pluviométrique sur les rendements agricoles au Togo

Abstract : The relations between the seasonal pluviometric indices and the agricultural fluctuations (productions and outputs) do not show very significant results. The study of the confrontation of the decadal pluviometric rates/rhythms and the decadal requirements
out of water for the various vegetative stages for corn taken in example, highlight the effects of the pluviometric disordered state on the satisfaction of the requirements out of water for corn at each vegetative stage for its development. It shows that pluviometric pejoration often assigns the critical period to the hydrous stress of corn of 1982 to 2007. Also, the identified periods of pluviometric deficit decadal coincide they with the period very sensitive to the hydrous stress, from where dissatisfaction of the requirements out of water for the cultures on the
plan agroclimatic certain years.
