Paschal Nnaemeka, a recognized expert in crop science and agronomy, has shared vital insights with sunflower farmers, stressing the importance of effective pollination management to maximize crop yields and oil content.

In a recent discussion, Nnaemeka pointed out that while modern sunflower hybrids are bred for self-compatibility, the presence of insect pollinators, particularly bees, still plays a significant role in enhancing productivity. “Research shows that with bee pollination, sunflower seed yields can increase by nearly 50%, and oil content can improve as well,” he noted.

Nnaemeka emphasized the need for strategic placement of honey bee colonies, especially for those growing F1 hybrid seeds. “It’s crucial to position these colonies effectively to ensure the bees focus on your sunflowers, particularly if there are other attractive flowers nearby,” he advised. In fields without competing pollen sources, placing hives at one end of the field may suffice, but in areas with competition, he recommended spreading hives at intervals of 800 feet to ensure adequate pollination.

He also highlighted that certain sunflower varieties are more attractive to bees due to specific traits like short corolla lengths and high sucrose nectar, though these are not always prioritized in breeding. Nnaemeka urged farmers to consider these traits when selecting hybrids to boost pollinator activity in their fields.

Addressing pest management, Nnaemeka cautioned against the use of insecticides during flowering, as they can harm pollinating bees. “It’s vital to coordinate with local beekeepers and inform them of spray schedules so they can protect their colonies,” he said. He also suggested applying insecticides during times when bees are less active and choosing bee-friendly products where possible.

Nnaemeka concluded by stating that careful management of both pollination and pest control is key to improving the yield and quality of sunflower crops, urging farmers to take these strategies seriously for better outcomes.

This guidance from Paschal Nnaemeka comes as sunflower farming continues to grow in importance, with farmers increasingly looking for ways to optimize production and ensure high-quality yields.
