“…Humic acid application (soil + spray) gave the highest values for seed yield/ plant (63.11 and 60.54 g) and seed yield/ha (2019.52 and 1937.38 kg) compared with soil or foliar spray humic acid. These results were in agreement with those obtained by (El-Nasharty et al, 2017) . Moreover, addition of humic substances has been recorded to enhance plant growth and soil properties, which are positively affected in higher crop yields and quality (Selim et al, 2009 andOsman andRady, 2012).…”

“…Also, the same trend was obtained for seed oil % where, combination of humic acid soil and foliar application had the highest values (37.15 and 37.22 %) in the two summer seasons, respectively. These results were in agreement with those obtained by (El-Nasharty et al, 2017) on sunflower under saline stress conditions. In addition, the interaction effect between sunflower genotypes and humic acid application were significant on seed protein %.…”

“…The harmful effects of salt stress were significantly suppressed by application of humic acid where, the highest values of N with averages (2.674 and 2.738 %) and P (0.371 and 0.400 %) were recoded with sunflower plants treated with both soil and foliar application in the two seasons, respectively. El-Nasharty et al (2017) found that humic acid increased the nutrient content of sunflower plants (N, K, Ca, and Mg) under saline stress conditions. Barakat et al (2015) showed that application of potassium humate increased N, P and K contents.…”

“…Also, Khan et al (2012) reported that, soil or foliar application of humic acid increased plant height. Moreover, foliar spraying micronutrients combined with potassium humate increased plant height and stem diameter for sunflower under saline stress conditions (El-Nasharty et al, 2017).…”

A field experiment was conducted at El-bostan Farm, Faculty of Agriculture, Damanhur University in the two successive summer seasons of 2018 and 2019. The aim of this study was to investigate the effect of humic acid application on sunflower (Helianthus annuus L.) growth, yield & its components and some chemical constituents grown under saline soil conditions. The experiment was laid out in a split plot design in four replicates. The main plots were occupied by three sunflower genotypes Sakha 53, Giza 102 and Line 120. While subplots contained four treatments of humic acid (HA) i.e.; without HA (control), HA soil application, foliar HA spray and a combination of both foliar spray and soil addition of HA. The results showed that, different genotypes did not perform similarly under salinity stress conditions. Line 120 had the highest leaf area/plant, head diameter, seed yield/ plant and seed yield/ha. With regard to humic acid application, it caused improvement for most growth, physiological parameters, yield and its components compared to control. Obtained results also, showed that humic acid application as both soil and foliar spray on Line 120 and Sakha 53 led to obtain the highest values of most studied parameters in the two growing seasons. Finally, it could be concluded that humic acid application can ameliorate negative effects of salinity on sunflower.

“…In a recent study, application of Zn and B improved leaf area, head/stem diameter, achene yield and oil yield in sunflower (Kawade et al, 2018). In another study, the foliage application of a mixture of micronutrients [Zn 3%, B 0.3%, iron (Fe) 3% and manganese (Mn) 3%] improved the seed and oil yield in sunflower under salt stress (El-Nasharty et al, 2017). Kumbhar et al (2017) also reported that the application of combined Zn, B and Fe improved the availability of these micronutrients to sunflower plant.…”

The deficiency of micronutrients is one of the main reason for low seed yield in oilseed crops in many developing countries including Pakistan. Therefore, this two-year field study was conducted to assess the influence of foliage applied micronutrients (individual/or in combination) on the yield and quality of sunflower hybrids. For this study, we hypothesized that foliage application of micronutrients will improve achene yield, oil quality and net returns in sunflower hybrids. The results indicated that sunflower hybrid 'Parsun' produced the higher head diameter, and had more 1000-achene weight, achene yield, oil content, stearic acid, palmitic acid and linolenic acid as compared to 'FMC-1'. Likewise the tallest plants, greater number of leaves, maximum seed weight, the highest achene yield, and oil content were noted with the combined application of Zn+B. Highest achene yield with combined application of Zn+B also resulted in highest net income. The application of micronutrient also improved the oil content and oil quality. In conclusion, the hybrid 'Parsun' should be grown with the application of Zn+B (10 and 2 kg ha -1 respectively) to achieve higher achene yield, better seed quality and to earn higher net benefits in sunflower hybrids under arid climate of Layyah Punjab, Pakistan.
