摘要

In Assam, the coffee plantations are confined in Chirang, Karbi Anglong and Dima Hasao districts and also has the potentiality for expansion in the foot hill regions of lower Brahmaputra Valley and Hill agro-climatic zones of the state. Weed management is the biggest problem for coffee cultivation in the state and Mikania micrantha is one of the most problematic weeds in most of the coffee plantations. To quantify the infestation of the weed in and around coffee growing areas, a survey was conductedin five coffee plantations and 19 locations of other plantation crops as well as open forests covering an area of 355 km2 in Karbi Anglong district of Assam. M. micrantha infestation was negligible to low in coffee plantations, which received two roundsof manual weeding whereas, the infestation was moderate to high where only one manual weeding or no weeding was done. In open forest, the density of the weed was quite high. Among the coffee estates surveyed, the highest infestation of M. micrantha was observed in the estates surrounded by open forests and neglected other plantation crops which served as a good seed source for this weed.

Micrantha侵扰在咖啡种植园中可以忽略不计，咖啡种植园是两轮手册杂草，而侵扰则中等至高，那么只有一个手动除草或未完成任何手动。在开放林中，杂草的密度相当高。在调查的咖啡庄园中，在开放森林包围的屋苑和忽视其他种植作物的遗产中观察到最高的侵染，这是这种杂草的好种子来源。
