“…This might be due to the stimulatory effect of boron on sunflower and in enhancing metabolic process, pollen germination and improving development of pollen tube. These results also coincide with the findings of Shekhawat and Shivay (2008) and Imran khan et al, (2015). They reported that number of filled seeds/head and number of achenes/head were increased with boron application because of augmentation in pollen-production capacity of anthesis and pollen grain viability.…”

“…Whereas minimum stem diameter (l .66 cm) was recorded in plots where zinc was applied at 30 kg ha -1 which was statistically at par with Zn @ 0 and 10 kg ha -1 . These results matched with the investigations of Khan et al (2015) who stated that cell enlargement in growing tissues affected due to the deficiency of boron and it was involved in cell structure hence reduced stem diameter. The interaction between different levels of zinc and boron on stem diameter was also significant.…”

Sunflower is sensitive to boron (B) and zinc (Zn) deficiency when grown on deficient soil, A field experiment was conducted to determine the main and interactive effects of soil applied Zn and B on total production of sunflower at Agronomic Research Area, University of Agriculture, Faisalabad. Experiment was laid out in randomized complete block design (RCBI) with factorial arrangement using three replications with net plot size of 6 m x 4.5 m. The soil application of variable levels of Zn (0, 10, 20 and 30 kg ha-1) and B (0, 1, 2 and 3 kg ha-1) in the form of zinc sulphate and boric acid, respectively were applied at time of sowing. All other agronomic and plant protection practices were kept uniform. The data regarding growth, yield and quality parameters were noted by using standard procedures. Results showed that Zn @ 20 kg ha-1 and B @ 3 kg ha-1 significantly increased the number of plants per plot at harvest, stem diameter, head diameter, number of achenes per head, 1000-achene weight, biological yield and days to maturity, achene yield kg per, harvest index, leaf concentrations or Zn at heading stage, leaf concentrations of B at heading stage (ppm), achene oil content (%), achene protein contents as compared to control. This study concluded that higher growth and yield of sunflower can be achieved by application of Zn at 20 kg ha-1 and B at 3 kg ha-1 under Faisalabad conditions.

“…Cultivar Helio251 was the most sensitive to variations of B availability, because its productivity was greater with the highest B doses (5 and 8 kg ha -1 ) than with the other doses (Figure 1B). Khan et al (2015) also found a beneficial effect of applying B on the grain production of sunflower hybrids (Patron 551 and S-278).…”

Grain production, fatty acid and oil profile from sunflower cultivars receiving different boron doses

Among the main factors that affect the productivity of crops is deficiency of nutrients. Boron (B) is an essential micronutrient for plants, and sunflower is one of the most sensitive plants to deficiency of the element. Its inadequate supply can impair sunflower plants’ metabolism and grain and oil yield. The objective of this study was to assess the effect of different boron doses on the production of sunflower grains and the content and quality of the oil obtained from them. The experimental design was randomized blocks in a factorial scheme with three cultivars (Helio251, BRS323, BRS324) and four B doses (0, 2.5, 5.0, 8.0 kg ha-1). Two harvests were performed, the first in the R5 reproductive stage and the second at the end of the R9 cycle. In both cases, the levels of B in the capitulum were measured. At the end of the cycle, the grain yield, crude protein and oil content in the grains and fatty acid profile were analyzed. The cultivars responded differently to the treatments with B. The boron fertilization influenced the grain yield and oil content, but was not correlated with the profile of the majority unsaturated fatty acids and crude protein in the grains. Variations were observed in the fatty acid profile between the cultivars, an important aspect that needs to be evaluated according to the purpose of the production. In soil with lower availability of B, cultivar BRS323 was most efficient in B uptake, grain yield and oil content and quality.
