We all want the best possible yield from our crops, but have you ever considered that the key to success might lie in something as fundamental as the seed itself? Recent research from SGS, a scientific research company, in collaboration with the National Association of Agricultural Contractors (NAAC), sheds light on how important seed grading and cleaning is to the success of a crop’s establishment and yield.
For years, home-saving seed has been a popular and cost-effective method for farmers. However, this new research suggests that by simply removing small seeds and other undesirable material, farmers could see a significant boost in their crop yield – potentially up to 15%!
Why does seed size matter?
Jili Hewitt, NAAC Chief Executive, highlights a crucial point: “We know that seed size matters. This work shows the value of removing small seeds and other rubbish to ensure they get optimum performance from the crop they are drilling.”
Think about it – if you’re planting small seeds or other material that takes up valuable space in your drill, you’re not maximising your planting efficiency. These smaller seeds often lead to uneven growth, poor emergence, and can be more susceptible to weeds, stresses and diseases.
The research speaks volumes
The trials, conducted by SGS in controlled greenhouse conditions and then in field trials, compared the performance of five parcels of seed. The results were compelling: several key benefits were apparent with larger, better-sorted seeds, including greater emergence and early vigour, more mass, and increased root and tiller development.
The study even revealed a full 15% yield difference between the smallest and largest fractions of the seed. As Rob Barrie, NAAC’s Seed Section Chairman, emphasises farmers that are home-saving seed need to prioritise quality. “They need the biggest, boldest sample possible and the best hectolitre weight (HLW) they can achieve,” he states.
What this means for you
Nigel Day, seed consultant to the NAAC, notes that “this work suggests they should also consider seed size and quality and that using larger, more uniform seed can produce significant benefits.” He points out that with modern drills farmers now have the potential to achieve more accurate drilling than ever before, which optimises crop performance and selecting clean, viable seed is paramount.
Ultimately, investing in proper seed sorting isn’t just about maximising yield; it’s about building a foundation for healthier, more robust plants from the very beginning. Removing unviable seeds and other material also means wasting less and ensures every viable seed you plant contributes to a productive return.
