Analysis of the Superposition of Meteorological Data and Maize (Zea Mays) Planting Periods in Order to Reduce Production Losses Due to Climate Change in the Dry Savannah Zone of Togo

The purpose of this work is to determine the impacts climate change on planting periods in dry Savannah Togo. To attend goal, a survey was conducted among 47 maize producers, 23 whom were Kara region and 24 region. information collected supplemented by recommended Also, rainfall data over period at least 30 years processed Instat+ R software. superposition results obtained field meteorological shows that region, starts within encounters up 15 days drought. In savannah however, sowing done after period. both regions, 30% producers surveyed did resow because sudden interruption rainfall. More than 60% experienced spells 10 during growth stages crop. Resowing certified seed costs 110,600 f CFA/ha. Yield losses due drought area can reach 2 t/ha, representing financial loss 500,000 Faced with these losses, supplemental irrigation techniques could reduce effects
