Welcome to UC Grain Legume Workgroup
Our purpose is to provide an on-line repository of agronomic information about California grain legumes, specifically dry beans. We deliver up-to-date and research-based guidelines and information on dry bean crop management and production to California's growers, researchers, and industry professionals.
Please provide your comments and support for the following position:
CE Specialist in Grain Legumes and Cropping Systems
California agriculture is characterized by being extremely diverse and dynamic. This necessitates expertise and resources to be focused on the evolution of existing cropping systems and evaluation of new crops and legumes (both grain and cover crops) to ensure the long-term sustainability of California production systems and support the ‘farm to fork’ food system concept.
This CE Specialist position will focus on developing innovative new cropping systems for California farmers, based on improved grain legumes, cover crops, and newly introduced crops, and integrating these crops into sustainable new cropping systems. It will also be linked to the existing $70 million/yr grain legume industry.
This position will create new business opportunities for California agricultural enterprises, maximize net farm income, develop new grain legume, cover crop, and recently introduced crop opportunities that provide prospects for new foods, improved health, water conservation, crop rotation benefits, boosting soil organic matter and nitrogen in rotations, reduced pesticide use, environmental protection, and adaptation to global climate change.

Soil Temperatures for Planting Blackeye
& Large Lima Beans
A grower recently called to ask about the minimum soil temperature for planting blackeye and large lima beans. The University of California, Division of Agriculture and Natural Resources has produced production manuals for both blackeyes and limas. A general guideline for blackeyes is to plant as soon as the weather warms and the soil temperature in the seed zone (about 2.5 inches deep) reaches at least 66°F for the three days following planting. Under these conditions, blackeyes will emerge about three to five days after planting.... (read full article)
Scouting in Garbanzo Beans
A pest control advisor recently contacted us to ask what pests he should be scouting for in garbanzo beans. His clients had not grown garbanzos in the past but have some acreage this year. Given recent wet weather and relatively mild temperatures, there are three diseases for which we suggest keeping an eye out.
Ascochyta blight (Ascochyta rabiei, Didymella rabiei) is a particular problem in garbanzo beans... (read full article)

Garbanzo beans hit hard by Alfalfa Mosaic Virus in California in 2015
This disease is vectored by aphids with the common host of the virus including alfalfa. One usually won't see the aphids in the garbanzos; they just taste and either die or leave, probably due to the acidic exudate of the garbanzos that seems to deter them. It is not cost effective to spray the aphids for virus control. Instead, planting date is important to avoid aphid flights.
