Abstract
山藥台農2號於1996年命名，隨即於1997年推廣至14鄉鎮地區，推廣頗為迅速之因，與其兼具高產、質優且特性之表現甚為穩定有關。雖然台農2號之產量甚高且穩定，由1989至1992年在七地區之平均公頃產量達26.9 t/ha，但不同種植方式、栽培介質、施肥種類、種植期、生長期及行株距等因素，對其生產表現都有或多或少之影響。其中不同施肥種類、種植方式與栽培介質三因素之影響頗大，利用如甘藷般之種植方式栽培，配合化學肥料及少量牛糞肥，台農2號之平均公頃產量可達32.7 t/ha；利用50cm長度之半圓形塑膠穴管栽培台農2號，管內介質為牛糞肥：砂：田土=1:1:1時，其平均公頃產量為27.6 t/ha；若於半圓形塑膠穴管內，先換填蔗渣：牛糞肥=2:1之特定介質，再栽培台農2號，則其平均公頃產量可達41.3t/ha；若於半圓形塑膠穴管內，除了先填滿蔗渣：牛糞肥=2:l之介質外，穴管外之栽培田區另混施10 t/ha之牛糞肥，之後再栽培台農2號，則其平均公頃產量高達63.2 t/ha。在促成豐產之外，台農2號塊莖利用涼溫（17士1.50C）網袋貯藏方式，可以貯藏26週，此將有效解決台農2號之貯藏問題，延長塊莖之利用期限，並增加塊莖利用之可行性。
The yam variety Tainung No. 2 was registered and released for commercial production in 1996. Based on its high and stable yielding potential and high quality of tuber, it has been accepted and extended to 14 county areas throughout Taiwan in 1997. Although the mean tuber yield of Tainung No. 2 was relatively high and stable, a mean tuber yield of 26.9 t/ha had been obtained from 1989 to 1992 ,many factors such as year, location, elevation, fertilizer, planting date, growth duration, cultivating method and cultivating media, etc. could play a more or less important effect on its tuber yield. Experimental results showed that the mean tuber yield of Tainung No. 2 was 32.7 t/ha under normal cultivating method like sweet potato, when compared with a yield of 27.6 t/ha under cultivating with half plastic pipe, which was 50cm in length and was filled with mixed media of soil, sand, and cattle manure with a ratio of 1:1:1. But a yield of 41.3 t/ha was recorded, when the media in the half plastic pipe were changed by sugar-cane waste and cattle manure with a ratio of 2:1. In contrast with the yield obtained from the former cultivating method with half plastic pipe and mixed media of sugar-cane waste and cattle manure, a yield of 63.2 t/ha could be reached, when the plot soil was mixed with 10 t/ha of cattle manure before planting of Tainung No. 2. Besides higher tuber production of Tainung No. 2 had been achieved, a lengthening period for 26 weeks was obtained by storing tubers of Tainung No. 2 at 17±1.5℃, which can be very useful for tuber further usage purpose.
