Drones help rice farmers hone fertilizer application and reduce crop fungal diseases

University of California rice researchers are exploring a more precise way of deciding whether the crop would benefit from a side-dress nitrogen fertilizer application, using drone-mounted cameras. Hand-held Greenseeker-normalized difference vegetation index (NDVI) readings have already replaced color charts as a research tool for in-season fertilizer decisions, but drone photos of the normalized difference red…

Seed and Variety Improvement in Vegetable Production (video #9 of 26)

The allied seed and variety improvement industries are critically important aspects of vegetable production systems in California. Most vegetables are annuals and have to be started every year from seeds, so seed production is critical for the vegetable industry. Professors Kent Bradford and Diane Beckles, Research Scientist Roger Chetelat, and Ph.D. student Karin Albornoz, all…

UC Davis Releases Five New Strawberry Varieties – Publicly available plants will help farmers manage diseases, production costs

The Public Strawberry Breeding Program at the University of California, Davis, has released five new varieties that will help farmers manage diseases, control costs, and produce plenty of large, robust berries using less water, fertilizer, and pesticides. Two of the new varieties could increase yields by almost 30 percent.  “These new varieties are intrinsically different…

The California Tree Mortality Data Collection Network — Enhanced communication and collaboration among scientists and stakeholders

An article in the new issue of California Agriculture addresses how critical research and dialogue are underway to understand the consequences of the massive wave of tree mortality in the Sierra Nevada. Over 147 million dead trees were detected in California by the U.S. Forest Service from 2010 to 2018. The massive tree mortality, mostly…

Weed Management in Specialty Crop Production (video #7 of 26)

Competition from weeds can result in yield losses in California’s specialty crop systems. Weeds can also harbor pests and diseases. Weed management is an important component of vegetable production systems to maintain sustainability. Weed specialist Steve Fennimore (Department of Plant Sciences, UC Davis, and UC Agriculture and Natural Resources) is featured in this video, and…

Using Machine Learning to Predict Metabolic Pathways in Tomatoes

Understanding the steps in metabolic pathways is important for understanding health and disease, whether in people or plants. But figuring out these biochemical pathways is difficult and time consuming. So why not have a machine do it? Scientists at UC Davis and Ben-Gurion University in Israel have applied machine learning (artificial intelligence) techniques to this…
