Abstract:
Studies on water, nitrogen and mineral losses caused by weeds in rainfed wheat were carried out at the National Agricultural Research Centre (NARC), Islamabad. Among the weed species included in this study, carthamus (Carthamus oxyacantha Bieb.) was found to contain the highest percent moisture. Canarygrass (Phalaris minor Retz.), although low in density, caused the highest nitrogen-loss. Percent nitrogen content of carthamus was the highest, followed by sunspurge (Euphorbia helioscopia L.), fumitory (Fumaria indica L.), canarygrass and scarlet pimpernel (Anagallis arvensis L.) respectively. Weed species showed a similar trend in terms of mineral matter accumulation.
