• 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.

• This research was aimed to study the effect of stem and primary branch prunning on photosynthetic rate and production of physic nut. The experiment was conducted in IPB experimental station in Cikabayan, Darmaga, Bogor, from February 2007 until May 2008. A randomized block design with one factor was used in the experiment. The treatments were combination between stem pruning with various height from the soil surface and pruning of primary branches with various number of branch remained. Stem pruning on 40 cm above the soil surface with no branch pruning resulted in the highest photosynthetic rate (8.10 μmol CO2 m-2 s-1), while stem pruning on 20 cm above the soil surface with 2 primary branches remained resulted in the lowest photosynthetic rate (4.71 μmol CO2 m-2 s-1). Stem pruning on 40 cm above the soil surface without branch pruning produced the highest yield components, i.e., capsul number (207.3 capsul plant-1), seed number (506 seeds plant-1) and seed dry weight (323.81 g plant-1). Keywords: photosynthetic rate, production, stem prunning
