Drought stress is one of the abiotic factors that reduces crop production. The use of biofertilizers can mitigate the negative effects of drought stress and reduce chemical inputs on agricultural systems. In order to investigate the effect of combined management of chemical and biological fertilizers on yield and quality-related traits of black cumin (Nigella sativa L.) under different irrigati...

Recent field experiments have shown that high chloride (Cl) in irrigation waters can increase soil cadmium (Cd) uptake by crops because of the formation of soluble ion-pair complexes of Cd with Cl in soil solution. The present study was aimed at testing a hypothesis that KCl in granulated PK fertilizers may enhance Cd uptake by crops from Cd-containing P fertilizers because of close contact bet...
