The Similarity of Barnyardgrass Weed in Lowland Rice Fields Based on Seed Characteristics

In lowland rice areas, the presence of barnyardgrass weed (Echinochloa crus-galli) is disadvantageous to Indonesian farmers and requires an initial assessment and identification of characteristics for management. Therefore, this study aimed to obtain the characteristics and similarities of barnyardgrass accessions from lowland rice fields based on the morphological characteristics of the seed. A descriptive-analytical method was used to determine the barnyardgrass characteristics of 45 accessions from nine sub-districts in Serdang Bedagai and one accession from Medan City (MDN), Indonesia, as a comparison. This study was conducted from May to August 2022 and the data were analyzed using one-way ANOVA, followed by Tukey’s test at P
