Abstract: The need to reduce harmful effects from the indiscriminate use of herbicide has facilitated the development of weed management systems, which are based on ecological manipulations rather than agrochemicals. In this direction, utilizing allelopathic plants to suppress the weed may be the most cost-effective and environment-friendly method of weed control. In coriander, one of the popular seed spices, weed control is challenging as the crop is having a low degree of competitiveness against weeds particularly at the initial phases of its growth. Towards searching the allelopathic potential of some plants in managing the weeds of coriander, a few common Allium species like onion, garlic and leek are found effective as has been reported alongwith other crops in various parts of the world particularly due to their effects most often linked to volatile substances derived from sulphur amino acids. Reports are available on the allelopathic potential of wild onion (Asphodelus tenuifolius) on the germination and seedling growth of chickpea (Cicer arietinum). Welsh onion (Allium fistulosum) are found to exhibit distinct allelopathic effect on summer chrysanthemum by inhibiting rooting and early growth of the plants followed by wilting. Allium ursinum L. (wild garlic) is also found allelopathic for its phenolic acids and total phenolics content in the leaves, bulbs and soil. The present study is an attempt to search such potential allelopathic alliaceae crops which are very common, useful and substantiate the economy of the growers whenever grown alongwith the coriander crop.
