Abstract

Weeds are undesirable plants that compete with crops for essential resources such as nutrients, water, light, and space, thereby reducing agricultural productivity. Weed management is particularly challenging in species possessing underground rhizomes due to their high regenerative capacity. Although the flora of the Washim district was documented by Deore (2010), no comprehensive weed survey had been undertaken in the region over the past sixteen years. The present study was therefore conducted to update and document the weed diversity of the district.

A systematic field survey was carried out from 2020 to 2025 in irrigated and unirrigated agricultural fields across different talukas of Washim District. A total of 210 weed species belonging to 140 genera and 37 families were recorded. The genus Ipomoea was found to be the most dominant, while Poaceae emerged as the largest family with 38 species. Unirrigated fields were mainly dominated by Parthenium hysterophorus, celosia argentia, Xanthium strumarium, Boerhavia erecta, Euphorbia geniculata, Acalypha spp., and Phyllanthus spp. In contrast, irrigated fields showed dominance of Anagallis arvensis, Dinebra retroflexa, Melilotus alba, Convolvulus arvensis, Digera muricata, Moorochloa eruciformis, Launea procumbens, and Sonchus spp. The study provides updated baseline information on weed diversity that will support effective weed management and future ecological studies in the region.

Introduction

Weeds are establishing themselves in agricultural and non-agricultural habitats where they interfere with crop growth by competing for vital resources, leading to reduced yield and quality. Due to their high ecological adaptability, weeds are able to survive under diverse environmental conditions and are distributed across almost all climatic zones of the world. Among different weed categories, perennial weeds are particularly problematic in agriculture because of their persistence, vegetative reproduction, and ability to regenerate from underground structures such as rhizomes, making their management difficult.

Washim District is located in the eastern part of Maharashtra and covers an area of 5,095 km². The district is predominantly agricultural, with a major portion of the land under cultivation and a smaller area under forest cover. District comprises six talukas: Washim, Malegaon, Risod, Mangrulpir, Karanja, and Manora. The terrain is largely plain, with parts of the Ajanta Hills extending through the northern and central regions. The natural vegetation of the region is mainly dry deciduous forest.

The present study was undertaken to systematically document the weed flora of irrigated and unirrigated agricultural fields of Washim District, Maharashtra.

 

Material and Method

Weed specimens were collected from various localities within the study area, and field observations were recorded at the time of collection. These included habit, habitat, flower colour, fragrance, presence of latex, underground parts, plant height, local names, uses, and frequency of occurrence. Each specimen was assigned a unique field number.

Collected plants were processed using standard herbarium techniques, including drying and pressing. Identification was carried out with the help of standard taxonomic literature such as The Flora of the Presidency of Bombay (Cooke, 1903, 1908), Flora of Maharashtra State (Sharma et al., 1996; Naik, 1998), and other relevant floras (Singh et al., 2001; Singh and Karthikeyan, 2001).

Identified weed species were arranged family-wise according to the classification of Bentham and Hooker. Within each family, genera and species were listed alphabetically, and relevant information on local names, habitat, distribution, and collection locality was documented.

Result and Discussion

            The survey documented a total of 210 weed species representing 140 genera and 37 families. Ipomoea emerged as the most dominant genus, while Poaceae was the largest family, comprising 38 species. Distinct differences in weed composition were observed between unirrigated and irrigated agricultural fields. Unirrigated fields were predominantly infested with Parthenium hysterophorus, Achyranthes aspera, Acalypha sp., Alternanthera sessillis , Xanthium strumarium, Boerhavia erecta, Euphorbia geniculate, Tridax Procumbens, and Phyllanthus spp. In contrast, irrigated fields showed dominance of Anagallis arvensis, Dinebra retroflexa, Melilotus alba, Convolvulus arvensis, Digera muricata, Eragrostis japonica, Moorochloa eruciformis, Launea procumbens, and Sonchus spp. The observed variation in weed assemblages reflects the influence of irrigation practices on weed distribution. Overall, the results reveal substantial weed diversity in the agricultural landscapes of Washim District, and identification of dominant species under different field conditions provides valuable information for planning effective weed management strategies.
