Abstract

The Vegetation Analysis of Weeds in Corn (Zea mays L.) Plantation and Its Conjunction with Weed Control in Lambung Bukit, Padang, West Sumatra         Research about the vegetation analysis of weeds in corn (Zea mays L.) plantation and its conjunction with weed control in Kelurahan Lambung Bukit, Padang, West Sumatra had been conducted from March to Juny 2011 by using systematic squares method of 10 total plots with size 1x1 m2. It was found consist of 10 families, 15 genera,16 species and 1892 individuals weeds. Spermacoce alata (Rubiaceae) showed the highest value of Summed Dominance Ratio (23,17%) and the lowest rate of SDR Hedyotis sp., Cyperus cephalotes and Amaranthus sp. (0,65%). The diversity index of the weeds was H'= 1,2005 (moderate). Integrated weed management is a concept that prioritizes natural control by creating environmental conditions that not favorable for the development of weeds and improve the competitiveness of crops against weeds.Keywords: Weeds, corn, composition, structure, control ABSTRAK         Penelitian mengenai analisis vegetasi gulma pada pertanaman jagung dan hubungannya dengan pengendalian gulma di Kelurahan Lambung Bukit, Padang, Sumatera Barat telah dilaksanakan dari bulan Maret sampai Juni 2011. Penelitian dilakukan dengan menggunakan Metode Kuadrat sebanyak 10 plot dengan ukuran 1x1 m2. Pada penelitian ini didapatkan 10 famili, 15 genus, 16 jenis, dan 1892 individu gulma. Gulma yang memiliki nilai SDR tertinggi yaitu gulma jenis Spermacoce alata famili (Rubiaceae) dengan nilai Summed Dominance Ratio (SDR)  23,17 % dan nilai SDR terendah Hedyotis sp., Cyperus cephalotes dan Amaranthus sp. (0,65%). Nilai indeks dari keanekaragaman jenis gulma berada pada nilai H’ = 1,2005 (sedang). Pengelolaan gulma terpadu merupakan konsep yang mengutamakan pengendalian secara alami dengan menciptakan keadaan lingkungan yang tidak menguntungkan bagi perkembangan gulma dan meningkatkan daya saing tanaman terhadap gulmaKata Kunci: Gulma, Jagung, Komposisi, Struktur, Pengendalian
