Corn and Sorghum

Corn is one of the leading crops in the Delta by acreage. While most of the corn grown in California is 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.

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.

Sorghum Seeding Rate Trial

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.
