Heat-Stress and Lack of Moisture on Corn and Soybeans in SWNY
Joshua Putman, Field Crops and Forage Specialist
Southwest New York Dairy, Livestock and Field Crops Program

Last week, SWNY was experiencing severe heat as well as symptoms of drought stress and seen in many crops. Corn leaves were rolling, soybean leaves were flipped, leaf tissue was turning grey, and there was no sight of rain. Luckily, much of SWNY received 0.5-2.0 inches of rain over the weekend. However, the period of time that the heat and moisture stress occurred may have affected our overall yields. Drought stress during vegetative stages results in reduced stem and leaf cell expansion (shorter plants with less leaf area). When drought stress is combined with heat stress, vegetative development will progress more rapidly. Any stress that occurs during the sixth to eighth leaf stage (V6-V8) can result in fewer kernel rows, whereas stress from eighth leaf to seventeenth leaf stage (V8-V17) can result in fewer kernels per row. Field Crop Specialist, Josh Putman, is seeing tasseled corn fields at heights of only 4.5-5ft throughout SWNY. Contact Josh if you have questions about your crops.

Silvopasture on a Shoestring
October 7, 2025
Franklinville, NY
Join Joshua Greene, Director of Education at Trees For Graziers, Jonathan Bates, Statewide Agroforestry Educator, and Lynn Bliven, owner of Wild Geese Farm for a full day training event that will include classroom and hands-on sessions. The focus will be on DIY silvopasture projects on small grazing farms. We will address the practical considerations of tree establishment, protection, and maintenance while learning how silvopasture can help address your farm's resource concerns and enhance livestock grazing.
Optimizing the Economic Return of Pasture-Raised Slow-Growth and Conventional Broilers - Webinar
October 15, 2025 : Optimizing the Economic Return of Pasture-Raised Slow-Growth and Conventional Broilers - Webinar
Over the past three years, Cornell Cooperative Extension has worked with nearly 40 small farmers across NYS to gather information on the true costs of raising broilers (meat chickens) on pasture. This presentation is a summary of the findings of this research project.
