“…The combined application of B and Zn may have contributed to the increase in oil content in seeds through the potential impact on the protein content of leaves. Therefore, the optimal utilization of B and Zn has the potential to enhance the seed oil content [29,89]. The combined application of B and Zn resulted in a significant improvement in the yield and quality of oil in the current study.…”

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.

“…Moreover, genetic factors substantially in uence the proportion of mustard oil generated. In addition, the element Mn enhances cellular processes and plant growth, increasing oil production in Brassica napus 33 , Brassica juncea 62 and various Brassica species by Muhal et al ( 2014) 72 . Our study found that the simultaneous use of SA and Mn had a more signi cant effect on grain oil content than using only SA or Mn individually.…”

“…This leads to an augmentation of the leaf area index and enhances physiological activities. In addition, the application of micronutrients to the leaves of plants activates around 35 enzymes involved in metabolic pathways, thereby improving the process of photosynthesis 33 . The application of MnSO on leaves has been shown to increase the overall chlorophyll content in leaves due to its positive impact on cellular metabolic processes 34 .…”

As an oilseed crop, mustard—a plant in the family Brassicaceae—is essential in India and worldwide. Crucial to plant metabolism are manganese and salicylic acid. We performed a field experiment to determine how they affected Indian mustard (Brassica juncea). Using a Randomized Block Design with three replications, the experiment included ten treatment combinations. These included control groups, different doses of sole salicylic acid (75, 150, 300 ppm), sole manganese (0.25, 0.5, 0.75 mM MnSO4), and combinations of the two. According to the experimental results, increasing dosages of both manganese and salicylic acid reversed the effects of sole foliar application by increasing the mustard growth and biochemical properties. It is worth mentioning that the addition of 0.5 mM manganese and 150 ppm salicylic acid externally increased stem dry weight by 1.24-fold, total chlorophyll content by 2.35-fold, relative water content by 1.25-fold, grain protein content by 1.11-fold, and oil content by 1.19-fold. To top it all off, the leaf membrane injury index went down by 36.2–53.2% after the combined application. The combination of salicylic acid and manganese yielded superior outcomes in optimizing growth dynamics and quality potential compared to individual applications of either compound.

P akistan is facing shortage of edible oil as gap between its demand and yield is increasing day by day. Local production and demand of edible oil are 0.374 and 3.291 million tones, respectively. The gap of 2.917 m. tones of edible oil is bridged up by import that is of value US$ 3.419 billion. Increase in edible oil is vital to meet domestic demand and industrial products while also conserving foreign currency, Abstract | To identify the influence of the integrated boron and zinc application on canola's (Brassica juncea) growth, quality and yield, a field trial was performed at research farm, Agriculture College, University of Sargodha, Punjab, Pakistan during winter season 2020-21. Treatments comprised of three B (0, 1, and 2 kg ha -1 ) and three Zn (0, 8, and 10 kg ha -1 ) levels and their all-possible combinations as their basal application to soil as boric acid and ZnSO 4 fertilizers, respectively. RCBD with three blocks was applied. Seed of AARI Canola variety was sown in 45 cm apart rows. Maximum CGR (155 g m -2 day -1 ), total dry matter (10663 kg ha -1 ), LAD (360 days), LAI (4.6), and NAR (34.4 g m -2 day -1 ), plant height (195.0 cm), and silique length (6.06 cm) biological yield (15.67 tons ha -1 ), seed yield (3.85 t ha -1 ) and oil yield (1188.3 kg ha -1 ) of canola were recorded with 2 kg ha -1 B + 10 kg ha -1 Zn treatment. The enhancement in seed and oil yield of canola seems to be due to improvement in seeds per silique (29) and 1000-seed weight (4.25 g). A synergistic relationship might exist between these two nutrients as their combined application showed greater effect in enhancing growth and yield of canola over sole application. Further, both nutrients enhanced the uptake of each other. We concluded that the application of 10 kg ha -1 zinc combined with 2 kg ha -1 boron can maximize the canola yield, net benefit (Rs. 706765) and benefit cost ratio (3.47), and therefore recommend this a feasible production technology for canola.
