Abstract


This research was conducted to study the varieties and various spacing  on the growth and yield of
the sorghum under the immature plants 1 of oil palm land. The research was held at Paya Robah
village, west Binjai district, north Sumatra province from June-September 2014, using split plot
design with varieties (numbu and kawali) as main plot and spacing (75x15, 75x20, 75x25, 75x30
cm) as sub plot. Parameter observed were plant height, stem diameter, flowering time, harvesting
time, weight of panicle seed per sample, weight of panicle seed per sub plot, yield per sample, yield
per sub plot, and 1000 grains weight. The result showed that varieties significantly effect on plant
height, stem diameter, weight of panicle seed per sample, weight of panicle seed per sub plot, yield
per sub plot, and 1000 grains weight. Spacing was significantly effect on plant height, stem
diameter, flowering time, harvesting time, weight of panicle seed per sub plot, yield per sub plot.
There  were interaction between variety and spacing for stem diameter.  

Keywords: spacing, variety, sorghum
