Abstract

The study objective of was to assess the effectiveness of herbicide oxyfluorfen application and
cow manure to shift the composition of weeds, weed growth, and yield of soybean. The experiment
was conducted at the experimental station of Agricultural Faculty UPN "Veteran" Yogyakarta, 17
m altitude above sea level, soil type Regosol, in October 2009 to April 2010. This experiment using
soybean cultivar Willis. The experiment was designed in a factorial experiment with completely
randomized design by three replications. As the first factor is the dosage of cow manure; D
0
:
Without cow manure, D
1
: Fertilizer cow manure 10 tons /ha, D
2
: Fertilizer cow manure 20 ton/ha,
D
3
: Fertilizer cow manure 30 tons/ha. The second factor is the dosage of herbicide oxyfluorfen;
D
0
: Without herbicides (Dose 0 kg/ha (active ingredient = a.i), D
1
: Dosage 1 kg/ha a.i., D
2
: The
dose of 2 kg/ha a.i, D
3
: The dose of 3 kg ha/1 a.i. The observation were characteristics of weeds,
herbicide toxicity in plants, weight and number of nodules, growth, yield components and yield of
soybean, soybean planting is done by a spacing of 30 cm X 20 cm. Inoculation of soybean seeds
by using legin 5g/kg seed. Fertilization is done at planting with Urea, SP 36 and KCI respectively
at a dose of 50 kg / ha Urea, 150 kg / ha SP 36 and 75 kg ha/ KCI. Results showed that (1) there is
diversity of weed species on the result of herbicide oxyfluorfen and cow manure application, (2)
herbicides oxyfluorfen at tested dosage are not effective for controlling weeds C. rotundus L., (3)
Cow manure and herbicides oxyfluorfen does not affect the weight and number of effective
nodules and herbicide application until the tested dosage did not toxic in soybean (4) The
application of herbicide oxyfluorfen and cow manure with a higher dose would increase the yield
of soybean.
