Abstract


Growth Respons and Production of Black Soybean Varieties (Glycine max L.) based on Seed Size.
Use of yellow soybeans increases as the limited supply of black soybeans. Farmers to plant turn
yellow soybean seed in higher production and larger in size than black soybean seed generally small.
Size seed effect toward the utilization of soybean. The large seed size tends to be use as industrial raw
materials while the size of small seeds use as a seed plant back. The aim of this research is to
selection the use big size seed and small seed size from some varieties to increase production. Planted
on Community Land Pasar 1 Tanjung Sari, District Medan Selayang, Medan with a height of ± 25
meter above sea level on Mei until August 2012. Randomized Block Design from that is varieties
(Detam-1, Detam-2, Cikuray, and Mallika) and seed size (small seed size and big seed size) who the
treatment repeatedly 3 times. The parameters observased were plant height, number of branches on
main branches, flowering time, harvest time, number of pods per plant, number of pods containing,
number of empty pods, production per plant, number of small size seed per plant, number of medium
size seed per plant, and number of big size seed per plant. The research showed that the stastistic
analysis that varieties significant effects on plant height, number of branches on main branches,
flowering time, harvest time, number of pods per plant, number of pods containing, number of small
size seed per plant, number of medium size seed per plant, and number of big size seed per plant.
