Improving of Kidney Bean Production by Plant Spacing in Two Different Altitudes at South Central Timor Regency, Indonesia | Science Publications

摘要

> >The production of kidney bean as the source of protein andcarbohydrate for the people of South Central Timor Regency is still low, therefore the productionshould be increased. The aim of this study is to evaluate the growth and production of kidney bean based on thedifferent altitudes and spacings. The research was conducted at two different altitudes inSouthern Central Timor Regency, Indonesia. Nine spaces of planting system have been tried at eachaltitude. The research usednested design by 3 replications. The experimental plot was made of 3×4 m insize and there were 27 experimental plots on each altitude. Result of theresearch showed that kidney beans were produced and grown well on the medium altitude compared with the high altitude. The rainfall, light intensityand temperature were the most dominant climatic factors that affected thegrowth and production of kidney bean among altitudes. Spacing of 30×10 cm wasthe most suitable for both altitudes based on yield of the crops. Spacing of 50×30cm, 50×20 cm and 30×30 cm have provided better yield stability than otherspacing as a result of different altitudes.
