“…It is an inexpensive oil that helps individuals recover from malnutrition and improves their health, making it ideal for populations residing in developing nations [12]. Climate extremes, such as heat and drought stress [13][14][15], soil salinity [16], limited light availability [17], and waterlogging [18], are the major constraints significantly reducing the yield and oil quality of oilseed rape.…”

Oilseed crops require several micronutrients to support their physiological functions and reproductive phases. A deficiency of these nutrients can significantly reduce the yield and oil quality of oilseed crops. Soil application of micronutrients can reduce their deficiency and improve plant growth, yield, and oil quality. Oilseed rape (Brassica napus L.) is an important oilseed crop that produces oil with low levels of saturated fat and high levels of beneficial omega-3 fatty acids, which renders it a widely used cooking oil. However, the yield and oil quality of oilseed rape are significantly affected by the deficiency of boron (B) and zinc (Zn). This two-year field study determined the influence of sole and combined soil application of B and Zn on the physiological attributes of plants, seed and oil yields, and oil quality under semiarid climatic conditions. Nine different B and Z combinations, i.e., B0 + Zn0 (control), B0 + Zn8, B0 + Zn10, B1 + Zn0, B1 + Zn8, B1 + Zn10, B2 + Zn0, B2 + Zn8, and B2 + Zn10 (kg ha−1), were included in the study. Sole and combined application of B and Zn significantly altered physiological attributes, seed and oil yields, and oil quality. The highest values for plant height, number of siliques per plant, number of seeds per silique, 1000-seed weight, seed and oil yields, oil quality (higher stearic acid, palmitic acid, oleic acid, linoleic acid, linolenic acid, and lower erucic acid), and physiological traits (protein concentration, soluble sugar concentration, chlorophyll concentration, photosynthesis and transpiration rates, and stomatal conductance) were recorded with the combined application of 2 + 8 kg ha−1 B and Zn, respectively, during both years of this study. The lowest values of yield- and oil-quality-related traits and physiological attributes were recorded for the control treatment. A dose-dependent improvement was recorded in B and Zn contents in leaves, and the highest values were recorded with the combined soil application of 2 + 10 kg ha−1 B + Zn, respectively. It can be concluded that 2 + 8 kg ha−1 B + Zn should be applied to oilseed rape for higher seed and oil yields and better oil quality under semiarid climatic conditions.

“…Foliar application of Si noticeably raised yield components such as cob length and diameter, 100 seed weight and cob yield in both non stress and drought stress conditions (Table 4). Lower 1 000 seed weight resulting from drought stress may be due to lower uptake of water and nutrients by the plant and so decreases in the synthesis and transfer of photosynthates and assimilates to seeds; in this situation, the plant can compensate for the shortage of assimilates even by retransferring nutrient resources and seeds become lighter (Aghdam et al 2019). Under drought conditions, Si foliar application increased 1 000 seed weight (Table 4).…”

Super sweet corn (Zea mays L. var. Saccharata) is one of the important and strategic crops, not only due to the short growing season for summer planting (Mokhtarpour et al. 2008) but also for the accumulation of higher quantities of sugars and the soluble polysaccharides in the grain of the endosperm (Paykarestan et al. 2019).Agricultural production is influenced by various abiotic stresses, such as drought (Swain and Routt 2017). In arid regions, drought stress is one of the most important challenges to the summer planting crops such as sweet corn (Ahmadi et al. 2013). Therefore, due to the limited water resources in agriculture, adopting any strategy to conserve water is very important. One of these strategies is irrigation cut-off with the least yield reduction.Therefore, technologies that depreciate the effects of water stress in sweet corn should be assessed. One

“…These findings are consistent with those of [36] who found that the oil contents (%) of different varieties of rapeseed oil from Roma, Italy ranged from 25% to 41%, with an average value of 33.1%, which are exaggerated by environmental surroundings and genotypes. In another study, it was reported that the total oil contents of rapeseed cultivars ranged from 21.0% to 47.3% [37,38].…”

There has been an increased interest in oilseed crops for agro-industry research and development breeding programs to secure sustainable food and agriculture. The introgression of exotic genotypes of oilseed Brassica into cultivated relatives is inevitable in the genetic improvement of oilseed crops. This experimental attempt aimed to characterize the morphological and molecular basis for the identification and characterization of some Brassica genotypes. Fatty acid profile, yield, and morphology are under genetic control and can be used to identify genotypes. Characterization and identification were fulfilled for five accessions from Brassica spp. Plant height, height of first branch, number of branches and pods per plant, seed yield per plant, average pod length, number of seeds per pod, protein and oil contents (%), and fatty acid profile were examined. Besides, the relationship between seed yield and seed yield-contributing characteristics was estimated, as well as the phylogenetic relationship of the internal transcribed spacer (ITS). The genotypes varied significantly for all examined traits, taking into account the most important traits: seed yield per plant and oil content. For example, oil content in the samples ranged between 41.1 and 49.3%. Path analysis results showed a high and positive direct effect between each number of primary branches and the number of pods per plant with seed yield per plant (0.48). The morphological and molecular observations suggest that the Fay1, Fay3, Fay4, and Fay6 accessions belong to Brassica rapa, while Fay2 belongs to Brassica carinata. It can be concluded based on the present findings that the Fay3 genotype with the highest oil content and the lowest erucic acid content compared to the other genotypes can be proposed as a potential donor for future breeding programs for oil production and quality, while Fay1 can be utilized as donor to increase the seed yield per plant.
