Taking the stress out of growing corn

Global warming is bringing longer growing seasons, allowing producers to expand the types of crops they cultivate. While this can be a benefit, a longer growing season increases the risk of environmental stressors, like frost and cool overnight temperatures.

Researchers from USask are investigating how the first frost impacts corn varieties, in the hopes of finding new ways to maximize crop yields.

“With global climate change, we are realizing that you can push the corn belt northward, so we’re wondering how we can enable the production of that crop by expanding the season,” said Dr. Karen Tanino, professor of abiotic stress physiology in the College of Agriculture and Bioresources.

The team is interested in the cuticular layer of the plant, a defensive barrier that acts like the plant’s skin. If the cuticular layer is more water repellent, it is full of waxy compounds that allow water to run off the plant.

“If water is not present, then the frost is not able to form, which means the plant can avoid that first fall frost,” said Tanino.

Agricultural Market Update: Grain Prices, Crop Conditions, and Weather Impacts

Welcome back to our channel where we provide comprehensive updates on the latest trends and changes in the agricultural sector. This week, we're looking at significant movements in grain prices, crop conditions, and the effects of weather patterns. Let's dive into the details:

Grain Price Decline Grain prices have fallen to their lowest levels since 2020, with December corn down 4.3% and November soybeans losing 3.1%. This decline is partly due to the beneficial moisture brought by Hurricane Beryl to the Midwest, which has improved crop conditions significantly. The USDA reported that corn and soybean crops are in their best condition in four years, contributing to the downward pressure on prices.

Record Short Positions and Market Sentiment Fund traders have increased their net short positions in the corn market to a record level, with a net short of 347,000 contracts of corn. This reflects a bearish sentiment in the market, further influencing grain price dynamics. Similar selling trends were observed in soybeans and SRW wheat, indicating broad market caution.

Weather Impact and Forecast Hurricane Beryl has brought significant rainfall across Arkansas, Missouri, western Tennessee, western Kentucky, and southern Illinois, with more expected over Missouri, Illinois, and Indiana in the coming days. Despite this, the market is currently more focused on the moisture benefits rather than potential heat risks forecasted in the 6-10 and 8-14 day periods.

US Crop Conditions Corn and soybean conditions have shown slight improvements last week, with corn rated 68% good to excellent and soybeans at 68%. These are among the best ratings for this time of year since 2020, suggesting robust crop health that could continue to influence grain prices.

Winter Wheat Harvest and Spring Wheat Conditions The US winter wheat harvest is progressing well, ahead of schedule with significant portions already harvested in Kansas and Texas. Spring wheat conditions are also favorable, with 75% rated good to excellent, although there have been some declines in states like Idaho, South Dakota, and Washington. Brazil's Corn Harvest and US Exports Brazil's second corn crop harvest is advancing rapidly due to favorable hot and dry conditions, with 63% of the crop already harvested. Meanwhile, US corn shipments saw a substantial increase last week, indicating strong export demand, which contrasts with the recent drop in domestic grain prices.

Ongoing Developments Lastly, the USDA reported a flash sale of corn, with significant quantities sold to unknown destinations, scheduled for delivery over the next two marketing years. This could signal ongoing international demand for US corn despite lower prices.
