Abstract
Differences in weed
diversity in paddy fields can occur due to different cultivation technology
factors. The population density in paddy rice weed communities can affect the
level of weed competition with plants. The research objective was to determine
the relationship between planting and weeding system technology on weed
diversity in lowland rice. The method used is the experimental method with
Split Plot Design as the main plot is the cultivation system (S) and the
subplot is weeding frequency (P). The data obtained is used to analyze the
Summed Dominance Ratio (SDR), and the Diversity Index (H’) value. The results
showed that lowland rice cultivation technology and weeding frequency had an
effect on the weed species found. The SRI system found 12 species, the
conventional system found 13 species and the zerotillage system found 14 species. If no weeding is
carried out, the dominant weed in the SRI and conventional systems is Cyperus
difformis, while in the zerotillage system, it is Sphenoclea zeylanica. Cultivation
technology interacts with the frequency of weeding on the weed diversity index,
with low to moderate levels of diversity.
