PENGARUH PEMBERIAN ETHEPON TERHADAP PRODUKSI TANAMAN KEDELAI (GLYCINE MAX L. MERRIL) PADA JARAK TANAM BERBEDA
Abstract: Application of
ethepon on soybean grown under densely population is expected to enhance plant
growth and increase assimilate translocation to seed. Ethrel 40 PGR is chemical
compound containing ethepon, when it is
in plant organ would be converted to ethylene and may accelerate flowering.
This study aims to determine the effect of ethepon on soybean crop production
under two different planting spaces. 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 plot and two levels of
planting spaces ie; 40 cm x 15 cm and 40 cm x 20 cm were assigned as subplot.
Traits observed were plant height, days to flower, days to harvest, filled pod
numbers per plant, seeds number per plant, grain yield m² and 100-seed weight.
The results showed that applicqation of ethepon shorten plant height,
accelerate day to flowering faster but delay harvesting time at planting space
of 40 cm x 15 cm and 40 cm x 20 cm. Yield components such as number of filled
pods per plant and grain yiel per unit area were lower due to application of
ethepon for both planting spaces. The
implication drawn from this research was that application of ethepon could not
be recommended for soybean.
