Abstract
The experiment was conducted to determine seeding density and nitrogen fertilizer doses for the MT10 rice variety grown in the winter-spring crop 2015/2016 and the Summer-Autumn crop 2016 in Ninh Thuan. Both experiments were established using a randomized complete block design with three replications. The seeding density experiment was performed in winter-spring season 2015/2016, including density levels of 120, 160, 200 and 250 kg/ha. The nitrogen fertilizer dosage experiment was organized in summer 2016, including 4 levels of 100, 120, 140 and 160 kg N/ha. Other non-experimental elements were identical. The results showed that the highest yield and economic efficiency were for the treatments of 200 kg seed/ha with a nitrogen fertilizer dose of 140 kg N/ha.
