Résumé : IN REUNION ISLAND, sugarcane is grown under highly contrasting climatic conditions, from the sea level to the highlands (up to 1000 m altitude), with very different soil types. Taking this diversity into account, a network of agronomic trials was implemented in 2005 on grower farms across the island. Four main fertilisation or amelioration techniques were tested: i) reduction of soil acidity using mill ash compared to liming materials, Mag lime and Physiolith; ii) sustainable nutrient management based on soil analysis, iii) effect of a slow release fertiliser-polymer-coated granular urea and iv) effect of splitting nitrogen application. In each trial, the traditional grower practices were used as control. Outcomes of the trials included: correction of soil acidity using mill ash with a sugar yield 10 to 23% higher than the control; a better sugar yield per ha using sustainable nutrient management (in one of two trials); a sugar yield loss using a reduced rate (-30%) of polymer-coated granular urea; a positive impact on ratoon yield when nitrogen application was split into two events. Such a network of trials should facilitate a faster adoption of research recommendations by the growers as it allows a direct exchange of information between sugarcane farmers and agronomists and addresses growers' issues.
