Efektivitas Beberapa Konsentrasi Herbisida Touchdown terhadap Gulma pada Areal Pertanaman Bawang Merah (Allium ascalonicum)

Abstract

Penelitian ini bertujuan untuk mengetahui konsentrasi herbisida Touchdown yang efektif dalain mengendalikan gulma pada areal pertanaman bawang merah dan dilaksanakan di desa Sei Rotan,. Kecamatan Percut Sei Tuan, Kabupaten Deli Serdang, sejak bulan April sampai Juni 2004. Penelitian ini dilaksattakan dengan menggunakan metode Rancangan Acak Kelompok (RAK) Non-Faktorial, dengan faktor perlakuan konsentrasi herbisida Touchdown (K) yang terdiri dari 3 taraf perlakuan, yaitu : Ki = konsentrasi 1,0 cc/I air K1 = konsentrasi 1,5 cc/I air KJ = lronsenuasi 2,0 cc/I air Dari basil penelitian diperoleh bahwa Herbisida Touchdown sang-at efektif dalain mengendalibn gulma berdatm lebar deopn rat.ma pmeoWe tiusbt kematian adalah sebesar 40,47 % sedangkan untuk gulma berdaun sempit rata-rata persentase kematian gulma adalah 19,05 %. This research aims to determine the concentration of Touchdown herbicide which is effective in controlling weeds in shallot planting areas and carried out in the village of Sei Rotan. Percut Sei Tuan District, Deli Regency Serdang, from April to June 2004. This research was carried out using the Random Design method Non-Factory Group (RAK), with the herbicide concentration treatment factor Touchdown (K) which consists of 3 levels of treatment, namely: Ki = concentration of 1.0 cc/I of water K1 = concentration of 1.5 cc/I of water KJ = lronsenuation 2.0 cc/I water From research results, it was found that Touchdown Herbicide is very effective in controlling wide-ranging weeds deopn rat.ma pmeoWe tiusbt mortality was 40.47% while for narrow-leaved weeds the average the percentage of weed death was 19.05%.
