บทคัดย่อ (EN): The productive potential of Napier grass a recently introduced energy crop was evaluated during the dry season in Chiang Mai province, Thailand. A field experiment was conducted to investigate the effects of various irrigation treatments, namely rainfed conditions, 0.5 x ET0 (Reference Evapotranspiration), 1.0 x ET0 , and nitrogen application rates of 0, 120, 240 and 300 kg N.ha-1, on biomass production of Napier grass. Nitrogen was applied two weeks after planting. Simultaneously, after the 1st harvest, ET0 was calculated and applied to the field by drip irrigation system every five days. Napier grass was harvested three times, firstly two months after planting, then at one and two months after the first harvest. The experimental results showed that applying 0.5 x ET0 could increase total dry matter yield of Napier grass from 4,344 kg.ha-1 under rainfed conditions to 6,260 kg.ha-1. Simultaneously, 240 kg N.ha-1 application was sufficient for reaching the statistically highest total dry matter yield from 2,340 to 7,911 kg.ha-1 compared with no nitrogen application. However, the interaction of 1.0 x ET0 and 300 kg N.ha-1 application could potentially reach above ground dry matter yield up to 12,000 kg DM.ha-1.
