- Documented the effect of environment and nitrogen nutrition on the nutrient / anti-nutrient status of amaranth and/or white and green asparagus.

- Documented the effect of conservation tillage in cotton and on the nutrients in broccoli and sweet corn.

- Evaluated the impact of reduced light in snap bean production.

- Determined the utility of particle film on tomato, pepper, and cotton for water stress management.
