COMBINED FOLIAGE APPLICATION OF ZINC AND BORON IMPROVES ACHENE YIELD, OIL QUALITY AND NET RETURNS IN SUNFLOWER HYBRIDS UNDER AN ARID CLIMATE

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