Abstract

The study objective of was to assess the efectiviness of herbicide oxyflourfen 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; Do: Without cow manure, Dı: Fertilizer cow manure 10 tons /ha, D2:Fertilizer cow manure 20 ton/ha,D3:Fertilizer cow manure 30 tons/ha. The second factor is the dosage of herbicide oxyflourfen; Do:Without herbicides (Dose 0 kg/ha (active ingredient=a.i), D1:Dosage 1 kg/ha a.i.,D2:The dose of 2 kg/ha a.i, D3: 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 KCl respectively at a dose of 50 kg / ha Urea, 150 kg / ha SP 36 and 75kg ha/ KCl. Results showed that (1) there is diversity of weed species on the result of herbicide oxyflourfen and cow manure application,(2) herbicides oxyflourfen at tested dosage are not effective for controlling weeds C. rotundus L., (3) Cow manure and herbicides oxyflourfen 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 oxyflourfen and cow manure with a higher dose would increase the yield of soybean.
