...orted to contain several allelochemicals. Utilization of these allelochemicals is considered low-cost and natural sources for weed suppression. Field trials were undertaken at Cotton Section, Agriculture Research Institute, Tandojam Pakistan during summer 2010 and repeated during summer 2011 for validating the previous results. The experiments were laid out in three replicated randomized complete block de...

The study revealed that in case of plant extracts maximum growth inhibition (35.90 %) was shown by Anar followed by Chabir (33.60%) and Garlic (29.16%), while minimum growth inhibition was recorded ...

The dates moth Ectomyelois ceratoniae is considered one of the most dangerous pests threatening date production in Algeria. Our results show that the highest relative rate of intake (RRI) and relative growth rate (RGR) were observed in larvae fed by Deglet Nour variety just as The efficiency of biomass conversion of digested food (EC...

Phytotoxic effect of poppy (P. somniferum) was examined on emergence and initial seedling growth of red rice (Oryza punctate L.). Aqueous extract of different plant parts (leaves, stem and flower) was used at various concentrations (0.25%, 0.5%, 1%, 2%, 4% and 8%) along with distilled water as control. The aqueous extracts of leaves, stem...

The experiment comprised of aqueous extracts of leaf, roots and fruits applied at 0.25, 0.5, 1, 2, 4 and 8% (w/v) along with a control (0%). Data regarding seed emergence, emergence index, emergence percentage, root length, shoot length and seedling dry weight were recorded. All the tested concentrations of all the parts of S. oleraceus significantly inhibited the ...

Therefore, this study was planned to investigate the allopathic potential of aqueous extract of winter crop Papaver somniferum (opium) on summer weed Echinochloa cruss-galli (barnyard grass. The experiment comprised of seven concentrations (0, 0.25, 0.50, 1, 2, 4, and 8%) of different plant parts i.e., leaves, stem and flower of P. somniferumwere. All the te...
