Jackie Atim - CE Specialist Abiotic Stress

The abiotic stress research program focuses on the sorghum crop with trials hosted at Kearney and Westside RECs as well as UC Davis. Forage and grain seed evaluations are conducted to provide growers with information on yields, growth parameters and forage nutritional composition. Deficit irrigation studies are conducted to identify drought tolerant commercial hybrid varieties in different environments and secondly determine the effect of water limitation on yields, the forage nutrient component and biofuel quality. Additionally, studies with Joint Bioenergy Institute (JBEI) are conducted on regulated and non-regulated sorghum lines to test yield performance as well as other phenotypic characteristics such as lodging, plant height, and plant form. The objectives of the field studies are to determine the effects of water supply limitations on the performance (yield and biofuel conversions) of advanced genetically engineered and non-engineered sorghum lines. Collaborative studies are conducted with USDA-ARS, Albany to determine causes and phenotypic consequences of bacterial enrichment patterns in the root endospheres of drought-stressed crop systems.
