various basidiomycetes and deuteromycetes, grown in liquid and solid culture media, were compared for their laccase-producing ability and for the inducing effect of soil and agricultural residues on laccase production. laccase activity in extracts of all solid media was higher than that of the liquid media. in liquid cultures, fungal laccase activity in ex-tracts of pea (pisum sativum) straw-tr...

abstract leaving crop residues on the soil surface may significantly affect the behavior and activity of herbicides. to probe this effect, a factorial experiment in a randomized complete block design with three replications was conducted using two factors including different rates of wheat surface residue (0, 1250, 2500 and 3750 kg ha-1 ) and different rates of trifluralin (%48 ec) herbicide (7...

To find suitable farming management approaches in the semi-arid climate of Iran, we set up an experiment combining three farm practices with four crop rotation systems over growing seasons (two winter and two summer seasons), from 2018 to 2020. The comprised: intensive (IF, inorganic inputs, removal residues soil, weeds chemically controlled), organic (OF, a return 30% mechanically integrated (...

poultry nutrition or inappropriate treatments by antibiotics can lead to production of eggs with antibiotic residues. the aim of the present study is to assess the prevalence of drug residues in eggs presented in kermanshah, iran. for this purpose, 120 eggs with the average weight of 60 grams were collected randomly from the supermarkets in kermanshah and later were tested for antibiotic residu...
