摘 要：The study investigated the response of Amaranth to irrigation depth and irrigation interval as well as poultry waste incorporation. A replicated 4 ×3 × 3 factorial arrangement with treatments consisting of percent organic matter incorporation （0%, 2%, 4% and 6% by weight）, irrigation interval （1, 3 and 5 days） and irrigation depth （4, 6 and 8 mm） was used for the experiment which was conducted in pots in a green house. The result of the experiment showed that percent organic matter incorporation, irrigation interval, and irrigation depth significantly （P 〈 0.05） affected the dry matter yield of the vegetable. However, only the percent organic matter incorporation and irrigation interval were significant （P 〈 0.05） in their effects on the plant height. The highest plant height of 12.03 cm occurred when 2% organic matter was incorporated into the soil while the lowest plant height of 9.04 cm occurred with 6% organic matter incorporation. The maximum plant yield （47.44 kg/ha） occurred when 2% poultry litter was incorporated into the soil while the lowest plant yield （31.57 kg/ha） occurred with the control experiment. Irrigation interval of three days as well as irrigation depth of 6 mm resulted in the highest plant height and maximum dry matter yield of the vegetable. From the result of the experiment, the factor combination of 2% organic matter incorporation with 6 mm irrigation depth applied at three days irrigation interval resulted in the highest plant height of 16.7 cm above ground surface and maximum yield of 67.8 kg/ha.
