The seeds of the medicinal plant dragon's head are an excellent source of fiber, oil, and protein, and are used to treat a variety of conditions, including certain nervous disorders, liver diseases, and kidney diseases. This study aimed to determine the effects of foliar application of various nano-chelate and chemical boron fertilizers on morphological indices of the dragon's head (Lallemantia iberica). This study employed a completely randomized design with nano-chelate (500, 1000, and 1500 mg/l) and boric acid (1000, 2000, and 3000 mg/l) treatments, in addition to a control group. The results demonstrated that the investigated treatments had a significant effect on the majority of dragon's head indices. The highest inflorescence length (43.66 cm) and number of cycles in the main branch (28.56) were observed in the boric acid treatment with 3000 mg/l of boric acid. The highest number of lateral branche, flower cycle per plant, and seed weight per plant, 1000-seed weight, and seed yields were obtained at 3000 mg/l of boric acid and 1500 mg/l of nano-chelated treatments, respectively. The highest number of seed per plant, plant dry weight, and biological yield were obtained in the treatments of 2000 and 3000 mg/l of boric acid and 1500 mg/l of nano-chelated boron fertilizers, respectively. Application of boron fertilizers significantly increased the nitrogen, phosphorus, potassium, and boron concentrations in the treated plants. In general, foliar application of boron micronutrient increased the yield and improved the indices of dragon’s head. Consequently, the application of nano-fertilizers yielded promising results due to their higher absorption efficiencies at lower concentrations than conventional fertilizers.

Bread wheat cultivars Chamran, Chamran2, and Sirvan are the dominant cultivars in Kerman province's warm regions. Due to their obsolescence and lack of purity, farmers are dissatisfied with the performance of common cultivars. Therefore, if the new cultivars outperform the conventional cultivars in terms of yield, they should be used to replace the conventional cultivars. The quantitative yield of 12 bread wheat cultivars was determined quantitatively in this experiment using a randomized complete block design with three replications. At a 5% probability level, the combined analysis of variance revealed that the year effect was significant for 1000-seed weight, plant height, and spike length. Additionally, at a 5% probability level, there is a significant difference between cultivars in terms of grain yield, 1000-seed weight, plant height, and spike length, indicating a genetic difference between cultivars. Sarang cultivar produced the most grain (7191.33) kg/ha, while the Chamran cultivar produced the least grain (6376.50 kg/ha). Sarang cultivar averaged 46.6 grams per 1000 seeds, while Shush cultivar averaged 35.1 grams per 1000 seeds. The Mehregan, Sirvan, and Tirgan cultivars, on the other hand, had the longest spikes at 10.16, 10.06, and 10 cm, respectively, while the Chamran2 cultivar had the shortest spikes at an average of 7.46 cm. The Chamran cultivar reached a height of 104.16 cm, while the Chamran2 and Aflac cultivars reached 94.33 and 94.16 cm, respectively. According to the findings of this study, Sarang, Shush, Khalil, and Tirgan wheat cultivars should be used in place of older and conventional cultivars in warm areas of Kerman province, depending on available facilities.

Salinity is one of the most important abiotic stresses because it causes zinc to precipitate in an unusable form for plants and is influenced by saline-calcareous soils. This experiment was carried out in a strip split block design with three replications at the Esfahan Rodasht Drainage and Salinity Research Station to investigate the effects of agrophysiological responses of barley genotypes to zinc fertilization and water saline irrigation. As vertical factors, water irrigation quality at three levels, 2, 10, and 18, dS/m, were used. Fertilizer application included Nano zinc-oxide, zinc-chelate, a mixture of Nano zinc-oxide and zinc-chelate, and water as a control. Within vertical factors, three different barley genotypes are arranged, including Morocco (moderate semi-sensitive), Nosrat (moderate tolerant), and Khatam (tolerant). The results showed that the application of Zn-chelate fertilizer resulted in the highest grain yield, K+ concentration, and K+/Na+ ratio in shoots. In Khatam, stomatal conductance (gs), the maximum quantum efficiency of PSII (Fv/Fm), K+ and Zn2+ concentrations, and the K+/Na+ ratio were all higher than in Morocco. In comparison to Morocco, Khatam had lower Na+ and Ca2++Na+ contents. Furthermore, as salinity stress increased, all barley genotypes showed a decreasing trend in K+ content and the K+/Na+ ratio in shoots.
