The researchers studied how different nutrients and sunflower varieties affect sunflower growth and yield. They tested phosphorus, sulphur, micronutrients, and humic acid on three sunflower types. The hybrid 'KBSH 1' had the highest yield, followed by 'Morden' and 'HA 234 B'. The combination of all nutrients led to the highest yield, similar to using recommended fertilizer with borax. The nutrients improved seed quality, increasing germination rate, seedling growth, and oil and protein content. Overall, the study showed that proper nutrient management can significantly enhance sunflower growth and yield.
