Abstract


Abstrak: Campuran herbisida dapat mengurangi ketahanan gulma terhadap herbisida dan meningkatkan kemampuan pengendalian gulma. Riset ini menggunakan Rancangan Acak Kelompok (RAK) pola non faktorial yang terdiri dari 9 perlakuan dan 3 kali ulangan. Masing-masing peubahnya yaitu persentase pengendalian gulma, persentase penutupan gulma, spesies gulma, jumlah individu gulma dan berat kering gulma. Aplikasi herbisida metribuzin, oksifluorfen dan pendimethalin berpengaruh terhadap persentase pengendalian gulma, persentase penutupan gulma, spesies gulma, individu gulma dan bobot kering gulma. Pencampuran herbisida metribuzin, oksifluorfen dan pendimethalin pada dosis yang sama 0,4 kg b.a ha-1 bisa memperluas tingkat pengendalian gulma, mengurangi tingkat penutupan gulma, spesies gulma, individu gulma dan bobot kering gulma pada tanaman kedelai.

 

Weed Characteristics due to Herbicide Applications of Metribuzin, Oxifluorfen and Pendimethalin on Soybean (Glycine max L. merril)

 

Abstract. Herbicide mixtures can reduce weed resistance to herbicides and improve weed control ability. This research used a non-factorial Randomised Complete Block Design (RCBD)  pattern consisting of 9 treatments and 3 replications. The variables were percentage of weed control, percentage of weed coverage, weed species, number of individual weeds and dry weight of weeds. Herbicide application of metribuzin, oxyfluorfen and pendimethalin affected the percentage of weed control, percentage of weed cover, weed species, individual weeds and weed dry weight. The herbicide mixture of metribuzin, oxifluorfen and pendimethalin at the same dose of 0.4 kg a.i ha-1 could expand the level of weed control, reduce the level of weed coverage, weed species, individual weeds and weed dry weight in soybean crops.
