Adaptability of the System of Rice Intensification (SRI) Under New Nitrogen Fertilization Techniques: The Case of Grison-Garde

The study tests whether the System of Rice Intensification (SRI) suits the Grison-Garde area, using the Jaragua rice variety. The 2016 trial used a completely randomized block design on 36,000 square meters, with 24 plots of 150 square meters: six treatments with four repetitions each. The treatments were granular urea, urea deep placement (UDP) briquettes, urea with sugarcane bagasse, UDP with bagasse, bagasse alone and a control.

Calculated yields ranged from 1.54 tonnes per hectare on the control to 3.11 tonnes per hectare with granular urea. The author concludes that SRI is suited to the area because most parameters differed significantly between treatments, and presents it as a tool toward rice self-sufficiency in Haiti. Eight recommendations cover water distribution, training, credit for growers, plant-protection products, post-harvest techniques and storage, and access to quality fertilizer and equipment.
