The production of kidney bean as the source of protein and carbohydrate for the people of South Central Timor Regency is still low, therefore the production should be increased. The aim of this stu dy is to evaluate the growth and production of kidney bean based on the different altitudes and spacings. The research was conducted at two different altitudes in Southern Central Timor Regency, Indonesia. Nine spaces of planting system have been tried at each altitude. The research used nested design by 3 replications. The experimental plot was made of 3×4 m in size and there were 27 experimental plots on each altitude. Result of the research showed that kidney beans were produced and grown well on the medium altitude compared with the high altitude. The rainfall, light intensity and temperature were the most dominant climatic factors that affected the growth and production of kidney bean among altitudes. Spacing of 30×10 cm was the most suitable for both altitudes based on yield of the crops. Spacing of 50×30 cm, 50×20 cm and 30×30 cm have provided better yield stability than other spacing as a result of different altitudes. © 2015 I Komang Sudarma, Nurul Aini and Karuniawan Puji Wicaksosno.
