Abstract

Wheat (Triticum Aestivum L.) is an imperative cereal and principal food source in the Indo-Pak continent and throughout the Globe. In the world, it is ranked first in cereal regarding cultivating area and production. Weeds hamper wheat by releasing allelochemicals through its body parts. Dumbi Sitti (Phalaris minor R) Family Poaceae is found to be a significant wheat weed. A scientific observation concerning allelopathy and interference of Phalaris minor in wheat is carried out in the Laboratory, Department of Agronomy, Faculty of Agriculture, Gomal University, D.I.Khan, KPK., Pakistan. In this trial, the influence of 15% aqueous extract of roots, stems, leaves, and whole plant parts was examined against the germination, emergence, and seedling development in Wheat. Aqueous extract of leaves had strong allelopathic potential (negative) that inhibited wheat germination (84% reduction in germination). Other parameters, such as MGT, germination index, seedling length, fresh and dry biomass, and growth parameters, were suppressed by leaf extract. It is concluded from this trial that Phalaris minor R. has a strong allelopathic influence on wheat seedlings. This weed is the most notorious and harmful among all winter annual weeds.
