ETHNO-PHARMACOLOGICAL RELEVANCE Cyperus rotundus L. (Cyperaceae) is a medicinal herb traditionally used to treat various clinical conditions at home such as diarrhea, diabetes, pyresis, inflammation, malaria, and stomach and bowel disorders. Currently, it is one of the most widespread, problematic, and economically damaging agronomic weeds, growing wildly(More)
A field experiment was conducted at, Agronomic Research Area, University of Agriculture, Faisalabad, Pakistan during spring 2008 to study the effect of new pre-emergence herbicide Penthalin plus-35EC (Pendimethalin 20 % + prometryn 15 %) on weeds, growth and yield of spring planted maize (Zea mays L.). The experiment comprised eight treatments: weedy check,(More)
Phytotoxic effects of parthenium residues incorporation and parthenium-infested rhizospheric soil on emergence and seedling growth of winter crops (wheat and canola) and weed species (wild oat and canary grass) were examined in different pot studies. In first experiment, parthenium whole plant residues were incorporated at 6 and 8 g kg(-1) soil five days(More)
Allelopathy is an important mechanism of plant interference mediated by the release of plant-produced secondary metabolites or decomposition products of microbes to the aerial or soil environment. It plays a key role in natural as well as cultivated ecosystems. Allelochemicals are released into the soil rhizosphere by a variety of mechanisms, including(More)
To investigate the effect of salicylic acid (SA) on growth and nitrogen metabolism in mungbean grown under saline conditions, an experiment was conducted in wire house in plastic pots containing soil + sand at NIAB Faisalabd. Mungbean (Vigna radiata L.) varieties, two salt tolerant (NM-98 and NM-92) and two salt sensitive (NM-54 and NM-13-1), identified in(More)
The carry-over effect of sub-lethal herbicides was investigated on the germination of seeds collected from surviving Chenopodium album plants, which had received 1/8, 1/8 twice, 1/8 three times, 1/4, 1/2, 1/1 doses of either pre-emergence ioxynil or post-emergence bentazone in a previous onion (Allium cepa) crop. Seeds were also collected from surviving C.(More)
The effect of ecological factors on germination of Emex spinosa was examined in laboratory experiments. Seeds were graded manually into large, medium and small, having weights 3.333, 1.952 and 0.886 g /100 seeds, respectively. Seeds germinated over a range of 10-20 °C, with optimum germination (89.17%) at 15 °C, showing a trend towards decrease in(More)
To assess the herbicidal potential of Eugenia jambolana Lam., Ricinus communis L., Ziziphus jujuba L. and Ziziphus mauritiana L. against noxious weed Parthenium hysterophorus L., germination bioassay using their 1%, 2%, 3%, 4% and 5% (w/v) and seedling growth bioassay using their 5% (w/v) (on dry weight basis) aqueous leaf extracts (ALE) were conducted. ALE(More)
Effect of weed competition periods on weeds and yield of black seed was studied through field experiments conducted at Agronomic Research Area, University of Agriculture, Faisalabad during winter 2006-07 and 2007-08. Weeds were allowed to compete with the crop for 40, 50, 60, 70, 80 days after sowing and throughout the growth season along with a weed free(More)
In the present study, large number of rhizobial strains were isolated from chickpea, lentil and mung been nodules and twenty fast growing colonies of each host legume, were selected. A series of jar experiments were executed and three most efficient isolates of each rhizobium species were screened on the basis of their growth promoting activities under(More)
