Walnut trees don't need water early in the season. UC Davis scientists are field-testing a new method that lets the trees tell farmers when to start irrigation, saving time, money and a precious resource.
Scientists have developed a new genetic tool that makes it easier and faster to breed grains that grow more efficiently and are better adapted to different environments. They're using a ground-breaking discovery: micro-RNA.
A UC Davis study found most California farmers acknowledge climate change and seek adaptation strategies. Key concerns include water shortages, extreme heat, and wildfires. Farmers need financial aid, research, and policy support to boost resilience.
UC Davis agronomist Bruce Linquist was named a 2024 Soil Science Society of America Fellow for his leadership in sustainable rice farming. His research on reducing tillage and water use helps farmers cut costs while improving soil health.
Problems faced by agriculture amid climate change are closely intertwined with non-ag issues. Solutions often have downsides. We have to embrace the complexity, talk to each other, innovate, use technology and be flexible to find solutions that feed us without causing harm to people and while improving and protecting the environment.
Alfalfa expert Charlie Brummer says it's time to "think about redesigning the alfalfa plant from first principles," after 40 years of frustrated efforts to increase yield. He made the remarks at a recent meeting of the North American Alfalfa Improvement Conference. Students also presented their research, including trials to grow the crop with less water.
UC researchers spent 20 years studying conservation agriculture in California, testing no-till, cover cropping, and residue management. Their findings show long-term benefits for soil health, water retention, and crop resilience, guiding future farming.
Doctoral student Valentina Roel is testing compost-based fertilizers from food and yard waste as eco-friendly nitrogen alternatives. Early results show similar crop yields to synthetic fertilizers, offering climate and soil benefits.
New UC Davis research shows winter cover crops don’t reduce soil moisture, countering water-use concerns. This supports sustainable farming and urges updates to groundwater models that may unfairly penalize growers.
UC Davis scientists have discovered the PLATZ1 gene in wheat. This gene controls plant height and boosts yield, especially in water-scarce conditions. It also helps produce longer coleoptiles for deeper planting, improving moisture access.
