A two-year factorial experiment based on a randomized complete block design with three replicates was carried out on barley cultivar LB-IRAN at the research farm of the Islamic Azad University, Ardabil, Iran, during the cropping years of 2019–2021, in order to survey the impact of plant growth-promoting rhizobacteria (PGPR) and nitrogen fertilizer on growth, yield, and remobilization of photosynthetic dry matter in barley. The first factor included five nitrogen levels: 0 (control), 25, 50, 75, 100 kg/ha net nitrogen; the second factor contained grain inoculations with four bacteria: no inoculation (control), Azotobacter chroococcum race 5, Azospirillum lipoferum race of, and …

Olive (Olea europaea L.) is one of the most important horticultural crops in Saudi Arabia. High temperatures are typical in most regions during the summer season. This study explored the effect of high temperatures on diverse olive cultivars (Manzanillo, Chemlali, and Picual) grown in three different geographical locations in Saudi Arabia (Sakaka, Basita, and Al-Qurayyat). Sakaka region was classified as a hot region, while the Basita and Al-Qurayyat regions were characterized by relatively mild or low temperatures. Genotypic components were assessed by studying Amplified Fragment Length Polymorphism (AFLP) molecular markers and physiological, anatomical, productive, and oil quality parameters. The …
