A field experiment was carried out during the winter (rabi) season of 2009–2010 and 2010–2011 at Chatha, Jammu to assess the yields of chickpea (Cicer arietinum L.) and Indian mustard [Brassica juncea (L.) czernj. & cosson] by computing intercropping indices along with weed-management practices. Significantly higher yields of chickpea (903 kg/ha) and Indian mustard (1, 156 kg/ha) were obtained in their respective sole crops. The highest land-equivalent ratio, aggressivity, land-use efficiency, production efficiency and relative crowding coefficient (RCC) were obtained in additive series and replacement series, whereas highest relative yield total (1.30) was recorded in replacement series. Among the weed-management treatments, pendimethalin @ 1 kg/ha recorded higher value of land-use efficiency (44.52) and production efficiency (7.35), followed by fluchloralin @ 1 kg/ha. Application of pendimethalin @ 1 kg/ha as pre-emergence recorded the maximum net returns (20, 373/ha) and benefit: cost ratio (1.71), followed by the application of fluchloralin @ 1 kg/ha.
