Research Reports from Local Trials - Delta Crops Resource Management

Corn is one of the leading crops in the Delta by acreage. While much of California’s corn is grown for silage, most of the corn grown in the Delta is for grain. My research and extension program provides locally-relevant information to enhance the efficiency, profitability, and stewardship of Delta corn production.

Delta Field Corn Variety Trial

The annual variety trial provides agronomic, disease, and yield information.

Nitrogen Stabilizers in Silage Corn

Fig. 1. Nitrogen stabilizers applied at sidedress fertilizer application.

Nitrogen stabilizers are an example of an enhanced efficiency fertilizer and are used to improve crop performance and nutrient management. This trial evaluated three treatments and a fertilizer-only control for improvements in crop yield and nitrogen uptake.

Seed Treatments for Wireworm Control in Field Corn

Wireworms are a soil-borne pest that are common in Delta muck soils. This trial evaluated new and commercial seed treatments for efficacy and crop performance.

Sorghum Seeding Rate Trial

During the drought (2012-2016), there was a shift in crop acreage away from grain corn to grain sorghum. Sorghum has similar growth habits as corn and is sometimes grown as a substitute for corn because of its tolerance of drought and low-input conditions.
