Impact of Pre-Planting Weed Control on Diversity Nematodes in the Rhizosphere of Corn Plants

DOI: 10.22161/ijeab.104.27

Abstract:
This study aims to determine the impact of several pre-planting weed control methods on the diversity of plant parasitic nematode species and their population levels in the rhizosphere of corn crops.The research was conducted from March to June 2024. On farmer's land in Binuang, Tapin Regency. The land observed is land No tillage + glyphosate, No tillage +sulphosate, Minimal tillage (on tractor), Minimal tillage (on tractor) + Oxadiazon, Minimal tillage (on tractor) + Butachlor, Conventional tillage (hoeing), Control (natural / no tillage).Observations based on the results of soil samples taken when the corn crop was harvested. The soil samples wereExtraction using a modified Baerman funnel (Dropkin 1991). Results of extraction of parasitic nematodes found identified based on morphological characteristics up to genus.Identification of nematodes refers to the books: Pictorial Key to Genera of Plant Parasitic Nematodes (Maiet al.1975). The results of research on the impact of pre-planting weed control on nematode diversity from corn rhizosphere samples found 16 nematode genera, Criconemella, Ditylenchus, Hemicycliophora, Hemicycl, Heterodera, Hirschmanniella, Longidorus, Meloidogyne, Paratylenchus, Pratylenchus, Psilenchus, Rotylenchus, Trichodorus, Tylenchorhynchus, Tylenchulus, Tylenchus, and there are variations in the genus and population of nematodes in each soil sample.
