During the drought simulation period, the precipitation during the three years experiments was far much few to cancel the water deficit induced. The average temperatures were higher enough (Figure 2) to allow soil drying during the drought period jugged by the fast decrease of soil moisture content during the stressed period (Figure 1). NERICA 1 showed better yields in both control and drought treatments (Table 2) confirming its ability to produce more than its two parents as discussed by Jones et al. (1997). The low availability of water during this work had less effect on the yields (Table 2). This might be due to its late occurrence during the rice plants life cycles. Similar
results were found by Boonjung and Fukai (1996). Husking yield gave an idea of the total amount of edible grains after
