Enhance stand establishment, increase crop adaptation to drought and heat stress (tolerance or resistance), maximize water productivity, improve product quality and nutrition for consumers, and ultimately enhance the economic returns for farmers and industry in the ‘farm to the table’ chain.  


In Texas, the sales value of fresh market and processed vegetables is estimated at $500 million. Crops included cabbage, cantaloupe, carrots, chili peppers, cucumbers, honeydew melons, spring and summer onions, spinach, squash, sweet corn, tomatoes, watermelon, snap beans, leafy greens, dry beans, southern peas, pumpkin, and potatoes.  National and statewide trends indicate an increased interest in the local production of ‘tasty’ vegetable crops in response to environmental and health concerns, population growth, as well as the potential for higher economic returns.  Thus, the future economic growth and increased health awareness are likely to cause an upsurge in global demand for vegetables.  This will cause major changes in the use of water, land, and environmental resources.
