KOMPOSISI VEGETASI GULMA PADA TANAMAN PISANG DAN JAGUNG LAHAN TEGALAN

Abstract

This study aimed to identify and compare the vegetation diversity of weed communities on banana and maize plants on dry land. This study was conducted in banana and corn plantations on dry land located in South OKU Regency, South Sumatra Province from March to April 2021. This study was used weed vegetation analysis using a quadratic method with 3 sample plots for each observation area. The data obtained in the analysis of weed vegetation include: density, dominance, frequency and SDR (summed dominance ratio). The results of the analysis of weed vegetation showed that the dominant weeds in maize plantation were annual weeds in the form of grasses (66.22%). The dominant weeds were Digitaria bicornis, Digitaria sanguilis, and Euphorbia heterophylla. The dominant weeds in banana plantations are annual weeds in the form of broadleaf weeds (100%). The types of weeds with the highest SDR values were Alfalfa invades, Ageratum conyzoides and Commelina benghalensis. Weed communities between maize and banana plants are heterogeneous (0,08%) or weed types that grow are different.
