RESPON TANAMAN KEDELAI (Glycine max (L) Merril) TERHADAP ETHEPON PADA JARAK TANAM YANG BERBEDA
Abstract: The objective of
this researchis to determine the response of soybean (Glycine max (L) Merril)
on application of ethepon under two planting spaces and to determine the
concentration of ethepon application for a specific planting space.A field
experiment was conducted by using split plot design, in which four levels of
ethepon concentration ie; 100 ppm, 200 ppm, 300 ppm and control were assigned
to main plots and two levels of planting spaces ie; 40 cm x 15 cm and 40 cm x 20 cm were assigned as subplot.
Parameters observed were plant height 35 days after planting, number of primary
branches, internode length of the main stem, plant growth rate, leaf area
index, days to flowering, grain yield per plot , and 100-seed weight. The data
were analyzed by analysis of variance andfurther investigated by least
significant difference atp = 0.05. The result shown thatethepon application
tented to shorten plant height and internodes height, lessen the number of
primary branches, decreased leaf area and leaf area index, accelerate flowering
dates and decreased grain yield per plot, but not for 100-seed weight. The
implication drawn from this research was that application of ethepon could not
be recommended for soybean.
