Study Highlights Environmental And Seasonal Effects On Maize Hybrids

Maize is a staple cereal across Africa that is also consumed globally. Rich in protein, the crop that is a significant source of dietary fiber in human nutrition is also one of the primary ingredients in animal feed production because of its high-energy content and digestibility.

However, for many years, farmers in rural Africa have lacked access to improved farming technologies, clean and pest-resistant seeds, and proper agronomic practices that will help reform the economic value of maize. Cultivated by rural farmers, maize has been identified as one of the crops that can combat global food shortages.

Video: R3 Corn Growth Stage Explained: Why Late-Season Tissue Sampling Matters

Corn pollination may be behind us, but the work isn't over.

In this field update from the Nutrien Innovation Farm in Champaign, Illinois, agronomist Tim Sickman discusses why growers should stay engaged with field scouting during the R3 (milk) stage of corn development. While favorable weather, strong pollination, and early grain fill are encouraging signs, important questions about crop nutrition and yield potential still remain.
