Corn, Seed

Seed corn producers are artists when it comes to timing the plantings of male and female inbreds. Pollination drives yield, and it is imperative seed producers ensure enough pollen is available for the receptive silks. Most seed corn producers add a second planting of males to shed the pollen over a longer window in time. The second peak of pollen shed expands the nicking zone and reduces missed nick. However, poor environmental conditions can quickly complicate this second planting.

BioNik™ plant growth regulator delivers flexibility and risk avoidance to seed corn producers. By using BioNik to delay germination on a portion of their male hybrids, corn seed producers are able to stretch out pollen shed to effectively blanket the silking period, resulting in a maximum nicking zone and no missed nick opportunity.

Single or Split Planting Chart
Pollen shed from single or split plantings of male inbred lines in seed corn fail to fully cover the female silking period, resulting in less-than-optimal yields.

BioNik Flexibility Benefits

  • Treat seed yourself vs. sending to a supplier
  • Save time and resources
  • Adjust rate close to planting as situation dictates
  • Treat some inbreds early and spread workload
  • Over-treat seed treatments to maintain current practice
  • Store product until next season to manage inventory

BioNik Risk Management Benefits

  • Prevent the need for split planting to offset considerable weather risk
  • Plant a male inbred mix of untreated and 1x BioNik rate to extend germination period and elongate the pollen shed window
  • Protect your female yield potential by optimizing the “nicking zone”
  • Make decisions in-season to adjust to weather patterns and planting dates
