Abstract
A field trial was undertaken at Regional Research Station (Hill Zone), Kali mpong, Darjeeling during the.year 2002 and 2003 with five different coloured polythene mulches on onion crop with the objective to observe the effect of different coloured polythene mulches on weed management as well as bulb yield. The result depicted significant reduction in weed population and biomass in blue coloured polythene mulch followed by black coloured mulch. Highest bulb yield was found in off-white coloured polythene mulch followed by blue and black coloured mulch and their increase in yield as compared to control were 54.2 1 %, 34.53% and 29.46% respectively. The highest mean net production value (rupees per rupee investment) was recorded in blue coloured polythene mulch (6.92) followed by black polythene mulch (6.80) .
