Grain Yield and Quality Traits of Durum Wheat (Triticum durum Desf.) Treated with Seaweed- and Humic Acid-Based Biostimulants

The ongoing climate change with increasingly frequent, prolonged drought during the vegetation period is a significant factor affecting production of field crops, including durum wheat (Triticum Desf.). One approaches to effectively protect plants from stress foliar application bioactive substances and selection appropriate genetic material for specific location conditions. In this study, impacts brown seaweed based humic substance-based biostimulants were researched. positive impact on grain yield has been reported in many studies. However, quality components questionable not well investigated. highly (? < 0.01) was confirmed. highest observed fertilized variant (4.03 t ha?1). When compared control, there high statistically difference. biofertilization weakly most cases, although without statistical significance > 0.05). study included evaluating interactions biofertilization–weather conditions (BW) biofertilization–variety (BV). According ANOVA results, BW found, BV, protein content, falling number, gluten content vitreousness found Correlation analysis among monitored parameters performed. results that we obtained multi-annual research may contribute sustainable arable farming areas lack rainfall vegetation. By substances, achieved increase while maintaining or increasing grain.
