摘要

A field study was carried out at the Botanical Garden of the University of Punjab, Pakistan, to investigate the yield losses by 6 commonly occurring and most abundant weeds in wheat field viz., Phalaris minor Retz., Rumex dentatus L., Coronopus didymus (L.) Sm., Medicago denticulata Willd., Chenopodium album L., and Poa annua L. These weeds were grown with two commercially grown wheat varieties viz., Inqalab 91 and Punjab 96 in 1:1 weed-crop ratio. Maximum yield losses of 76% in Inqalab 91 were caused by P. annua followed by 75% by C. didymus, whereas other weeds caused 60-70% yield losses. In case of Punjab 96, maximum yield reduction of 55% was caused by R. dentatus followed by P. minor (28%), M. denticulata, C. album (23%), C. didymus (10%) and P. annua (0%). Punjab 96 proved to be the comparatively resistant against weeds than Inqalab 91.

Didymus引起的75％，而其他杂草引起了60-70％的产量损失。在旁遮普邦96的情况下，最大产量降低55％的原因是牙本质红斑病菌，其次是小次要恶性疟原虫（28％），齿状分枝杆菌，白毛隐孢子虫（23％），迪迪姆氏假丝酵母（10％）和假单胞菌。年金（0％）。事实证明，与Inqalab 91相比，Punjab 96对杂草的抵抗力相对较高。
