ANALISIS VEGETASI DAN PENENTUAN DOMINANSI GULMA PADA PERTANAMAN JAGUNG DI BEBERAPA KETINGGIAN TEMPAT

This research was conducted to study weed species and weed dominance on maize crop at several altitutes in Kembaran districts (0-250 m alt) and Sumbang Districs (250-500 m alt), Banyumas regency. The research was arranged in a survey and weed vegetation analysis on maize crop at two different locations determined. There are 6 locations of maize crops every altitutes level (each 20mx20m). Every fields determined 10 samples plot (each 1mx1m). The results showed that weed dominance on maize crop (0-250 m alt) are Cynodon dactylon (SDR : 12,39), Eclipta prostrata (SDR : 11,09), Digitaria sanguinalis (SDR : 9,76), Leptochloa chinensis (SDR : 9,53) dan Cyperus rotundus (SDR : 8,82). Weed dominance on maize crop (250-500 m alt) are Eclipta prostrata (SDR : 13,78), Cynodon dactylon (SDR : 12,81), Leptochloa chinensis (SDR : 12,29), Cyperus rotundus (SDR : 11,47) dan Digitaria sanguinalis (SDR : 10,46)
