Corn Pollination Period The best time for natural corn pollination is defined by the synchronization of pollen shed and silk emergence, a period growers call “nick.” tassels typically begin shedding pollen one to three days before the first silks emerge from the ear shoot. Pollination is a critical period for corn development and yield. pollen shed occurs over a two week period. for kernels to develop, silks must emerge and be fertilized by viable pollen. silks grow about 1 to 1.5 inches a day and will continue to elongate until fertilized.
Corn Pollination Period Under good conditions, all silks will emerge and be ready for pollination within 3 to 5 days. this usually provides adequate time to pollinate all silks before pollen shed ceases. pollen of a given plant rarely fertilizes all the silks of the same plant. Next to planting and stand establishment, corn pollination and fertilization are among the most important phases of crop development. while successful pollination and fertilization depends greatly on growing conditions, there are several management considerations that can help optimize the process. If corn plants have ample water, pollen tubes complete their growth process within 12 to 18 hours. this time interval depends on where pollen grains land on silks; time intervals increase if pollen tubes must penetrate longer silk lengths. F ield corn in indiana typically enters the critical flowering stages of pollen shed and silk emergence sometime between late june to late july. success or failure during this period of the corn plant's life greatly influences the potential grain yield at harvest time.

Under ideal conditions, pollination occurs over a span of about 10 to 14 days. pollen typically sheds in the morning, when temperatures are cooler and humidity is higher, increasing the chances of successful fertilization. The pollination and reproductive process in a corn plant are critical to final yield, and there are several things that can happen to the corn plant during that two week period that can significantly reduce yield. Most corn hybrids regardless of maturity type will reach physiological maturity 60 to 65 days after pollination. corn is “safe” from a killing frost at physiological maturity. farmers in our area desire pollination to be completed by august 1 to insure maturity prior to the first killing frost. Explore the timeline for corn pollination and how to determine successful ovule fertilization.
