Seed production of annual weeds persisting through cropping phases replenishes/establishes viable seed banks from which these weeds will continue to interfere with crop production. Harvest weed seed control (HWSC) systems are now viewed as an effective means of interrupting this process by targeting mature weed seed, preventing seed bank inputs. However, the efficacy of these systems is directl...

Soybean and corn succession system widely adopt in different agricultural regions from Brazil. However, species incorporation, especially the autumn/winter season, can influence soybeans profitability farm economic return, providing benefits for sector. The objective this work was to analyze development of autumn-winter crop on soybean yield return Midwest Paraná, study conducted during 2019/20...

During the period 2003–2005, spring and winter cereal grain samples were analysed for the presence of the mycotoxins deoxynivalenol (DON), zearalenone (ZEN), T-2 toxin, ochratoxin A and aflatoxin (total) by the ELISA (enzyme-linked immunosorbent assay) method at the Lithuanian Institute of Agriculture. Mycotoxin DON produced by the fungi of the genus Fusarium was found to be most frequent in Li...

Preventing the introduction of weeds into the farming system through sowing of clean seeds is an essential component of weed management. The weed seed contamination of cleaned grain and herbicide resistance levels of the recovered weed seeds were examined in a study conducted across 74 farms in the Western Australian grainbelt. Most farmers grew and conserved their own crop seed. The majority o...

Wild oat is a widespread threat to annual crop production on the Canadian Prairies. Infestations are difficult manage due persistent seedbank, complex dormancy, long emergence window, herbicide resistance, and seed shatter corresponding harvest timings. The study objective was evaluate efficacy of potassium nitrate (KNO 3 ) pyroligneous acid for promoting germination wild volunteer wheat, barle...

Ornithine aminotransferase (OAT) is a reversible enzyme expressed mainly in the liver, kidney and intestine. OAT controls the interconversion of ornithine into glutamate semi-aldehyde, and is therefore involved in the metabolism of arginine and glutamine which play a major role in N homeostasis. We hypothesised that OAT could be a limiting step in glutamine-arginine interconversion. To study th...
