Ear Shake Test to Determine Corn Pollination Progress
Dr. Bob Nielsen, Purdue Extension Corn Agronomist, visits a cornfield during pollination in west central Indiana. Shown and discussed is a quick-test, by dissecting and shaking the corn ear, to check the progression of pollination. This test determines the success of ovule (kernel) fertilization, but cannot be used as a yield estimate. Fertilized kernels, if subjected to stress (e.g., drought) may still abort or poorly fill, causing reduced yields.
