• To determine the effects of pot sizes and the number of plants per pot on the growth of Amorphophallus muelleri, seed corms weighing 100-125 g were planted in polyethylene pots. In the first experiment, a corm was planted in pots containing various amounts of growth media: i.e., 0.25, 0.40, 0.50, 1.00, 1.33, 2.00 and 4.00 kg. In the second experiment, different numbers of plants, i.e., 1, 2, 3, 4 and 5, were grown in pots containing 4.00 kg of growth media. When plants were grown in pots containing a small amount of media (1.33 kg pot–1 or less), they produced small daughter corms and entered dormancy earlier than usual. The number of plants per pot had little effect on corm weight if the amount of growth media per plant was 0.80 kg or greater. As a result, corm yield increased with an increase in the number of plants per pot. The period from corm planting to harvest was slightly longer when only 1 plant was grown in a pot than when 2–5 plants were grown in the same-sized pot. This study suggested that the low productivity of A. muelleri in shallow soil was associated not only with a small amount of soil per plant but also with limited rooting volume.

• Productivity of Amorphophallus muelleri is considered low. Thus, pot experiment was conducted at the Cikabayan Experimental Farm, Bogor Indonesia during rainy season November 2007 to July 2008, in order to determine the optimum fertilizer dose for A. muelleri under 50% shading net. Treatments consisted of four doses of nitrogen (0, 50, 100 and 150 kg ha-1 N) and three doses of potassium (0, 50 and 100 kg ha-1 K2O). The results showed that application of N and K fertilizers significantly increased vegetative growth, i.e., number of leaves, number of leaflets and second leaf size, but did not affect harvesting time. Fresh weight and dry matter content of daughter corm were significantly affected by N and K applications. Combination of 50 kg ha-1 N and 100 kg ha-1 K2O resulted in higher corm weight than other treatments. It is evident that the application of nitrogen and potassium is important in A. muelleri.
