Short corn, short yields?
"An early start to soybean flowering is generally positive, but we remain concerned about how water shortages might affect soybean pod formation," Nafziger said.
The period over which new flowers appear will last for up to a month as the soybean plants continue to increase node numbers and stem height, and can even recur if stress is relieved after that. This longer flowering period makes the soybean crop better able to set pods and to start filling seeds even if there is some stress during July.
"But if we continue with little or no rainfall, abortion of flowers or of pods will likely continue," said Nafziger. As with corn, applying materials promoted to reduce stress in soybean is not likely to do much good as long as water supply remains inadequate.
