| ABSTRACT: Weed-induced yield loss in wheat crop is a great threat to food security in Pakistan. A comprehensive understanding of weed-crop competition is very important to develop sustainable and cost-effective weed management. For this purpose, two-year field studies were conducted to determine the effect of different blessed milkthistle densities on the phenology and yield of wheat crop in a rice-wheat cropping scheme in Sargodha, Pakistan during 2013-2014 and 2014-2015. The experiment comprised seven treatments: control (weed free), weedy check (weedy without any control) and blessed milkthistle densities of 5, 10, 15, 20 and 25 plants m-2. In response to increasing weed density, a gradual reduction in yield and yield-related traits of wheat was noted.... |

| ABSTRACT: Weeds have indirect effects on crop plants. Crop development is affected by allelopathy from certain weed species. Allelochemicals from allelopathic weeds can disturb the root and shoot growth of emerging crop seedlings, as well as cause several other types of damage. A study was carried out to investigate the allelopathic potential of Parthenium hysterophorus for weed response in soybean. The experiment was laid out in Randomized Complete Block Design (RCBD) with split plot arrangements and replicated thrice. Sowing methods (broadcast and line sowing) were kept in the main plot and mulching treatments (surface mulching and soil incorporation) were kept in the sub-plots. Mulching of Parthenium hysterophorus was applied at the rate of 1.0 t ha-1,... |

| ABSTRACT To determine the effect of Santa Maria (Parthenium hysterophrous) mulch on growth and yield of soybean, a study was conducted at the Department of Agronomy, Faculty of Agriculture, The University of Poonch, Rawalakot, Azad Jammu and Kashmir. The experiment was conducted in the laboratory as well as in the greenhouse. Parthenium surface mulch and soil incorporation was practiced at different levels in laboratory as well as in greenhouse. Higher allelopathic potential was found by the treatments of Parthenium soil incorporation, especially when soil incorporation of Parthenium herbage @ 5 ton ha-1 was practiced. This could be because of the presence of soil moisture that enhanced the decomposition of Parthenium therefore, retarded the growth and... |
