Severe photosynthetic stress during or shortly after pollination in corn often results in poorly filled ears due to incomplete pollination or abortion of young kernels.

Serious crop stress during the grain filling period of corn increases the risk of stalk rots and stalk lodging (breakage) prior to grain harvest.

With U.S. production outpacing usage for corn, soybeans and wheat, Purdue ag economists predict low prices will continue next year.

Farmers should be on the lookout for roots and sediment clogging their tile drains this year, a Purdue University soil physics specialist advises.

Excessive rain and cool temperatures this spring in northern Indiana, had many wondering how no-till and strip-till yields would stack up. The results are in from Purdue University's 41st year of long-term tillage plots near West Lafayette, IN, and they tell an interesting story.

The Purdue University-led Useful to Usable climate initiative is offering a new online tool to help farmers and farm advisers better manage the application of nitrogen fertilizer for maximum crop yields and minimum environmental damage.

Recent intense rainfall events (technically referred to as “toad stranglers� or “goose drownders�) have caused flooding of low-lying corn fields or ponding (standing water) in poorly drained swales within fields. Other areas within fields, while not technically flooded or ponded, may remain saturated for lengthy periods of time.

A new publication on Palmer amaranth, one of the most aggressive weeds to compete with crops, is now available for free through Purdue Extension's The Education Store. Palmer Amaranth Biology, Identification and Management was created by Purdue Extension weed scientists Bill Johnson and Travis Legleiter in an effort to curb the weed's expansion to the northern U.S.

Corn growers need to scout their fields to determine wireworm populations before planting so they don't miss the optimum treatment window, a Purdue Extension entomologist says. Wireworms, or click beetle larvae, feed on corn seed germ and may prevent plants from sprouting. The pest becomes active when soil temperatures warm into the upper 40s.

During a recent presentation at the 21st annual Conservation Tillage and Technology Conference held at Ohio Northern University in Ada, a Purdue University professor addressed farmers on improving drought tolerance for crops.
