Abstract
An experiment was conducted in irrigation rice field at Karang Ayu, Belitang Ogan Komering Ulu (OKU) from April to July 1994. The aims of the experiment was to examine the effect of nitrogen and fluroxypyr herbicide on weed infestation in rice field. The randomized completely block design in factorial arrangement was used. The treatments consisted of 3 levels nitrogen (60, 120, and 180 kg ha-1) and 5 levels dosage of fluroxypyr herbicide (0, 100, 200, 300, and 400 g a.i. ha-1). The result showed that nitrogen influenced the percentage of weed coverage, weed dry weight, plat height, biomass dry weight, and grain production. Fluroxypyr herbicide influenced crop phytotoxicity and all those parameters except plant height. The combination of 60 kg ha-1 nitrogen and fluroxypr herbicide dosage of 400 g a.e. ha-1 caused he highest weed growth suppression, indicated by the lowest level of weed dry weight (68,50 g m-2). While the combination of 180 kg ha-1 nitrogen and 300 kg a.e. ha-1 fluroxypyr herbicide produced the highest dry grain production of was 4,07 to ha-1.
