Scott, J. B., Gent, D. H., Pethybridge, S. J., Groom, T., and Hay, F. S. 2014. Crop damage from Sclerotinia crown rot and risk factors in pyrethrum. Plant Dis. 98:103-111. Sclerotinia crown rot, caused by Sclerotinia sclerotiorum and S. minor, is a prevalent disease in pyrethrum fields in Australia. Management involves fungicide applications during the rosette stage of plant development from au...

Nitrous oxide (N2O) is a strong greenhouse gas, and the emissions from managed soils are increasing. Emissions of N2O highly variable in time space, there potential triggers for emission peaks both crop season no-crop season. The aim this study was to compare how fertilizer treatments, differing rate source nitrogen (N), influence direct soil, as well season, with use automated, high-frequency ...

Progressive soil compaction is a disadvantage of intensive tillage. Compaction exerts negative impact on the physical properties and decreases crop performance. The adverse effects can be mitigated by replacing conventional tillage with simplified techniques. Simplified protective effect soil, reduces production costs preserves agricultural ecosystems. aim this study was to determine influence ...
