- Abstract:
- ... The in-season trend of onion biomass and its yield depend on the dynamics of nitrogen (N) and sulfur (S) uptake. This hypothesis was verified based on a three-year (2009, 2010, 2011) field study (Poznan University of Life Sciences). The experimental factors consisted of N: 0, 60, 120 and S: 0, 30, 60 kg ha⁻¹. The dynamics of onion total dry weight (TDW), total N uptake (TNU), and total S uptake (T ...

- Abstract:
- ... Gastrointestinal anthrax, a disease caused by Bacillus anthracis, remains an important but relatively neglected endemic disease of animals and humans in remote areas of the Indian subcontinent and some parts of Africa. Its initial symptoms include diarrhea and stomachache. In the current study, several common plants indicated for diarrhea, dysentery, stomachache or as stomachic as per traditional ...

In order to reduce production costs, we evaluated a control strategy that integrated the use of resistant experimental cultivar and a disease warning system. Regardless of the type of management adopted, the experimental cultivar was always more productive. In turn, management based on the ...

Prokaryotes produce endo and exotoxins, among others. Exotoxins are highly toxic, while endotoxins have milder toxic effects. The present study evaluated the cytotoxicogenetic potency of both toxins studying them in different conce ...
