Titre : Sesame Crop Yields Stable in Drought Conditions

Présentation
Texas has a long history of growing cotton. It’s a resilient crop, able to withstand big swings in temperature fairly well. However, growing cotton in the same fields year after year can be a bad idea. Nutrients can get depleted. Disease can lurk in the ground during the winter season, only to attack the following year. Thus, rotating cotton with other crops could be a better system.

Agronomists have been researching various alternative crops that will grow well in western Texas. This area is part of the Ogallala water aquifer, which has been hit extremely hard the past few decades by drought. Another crop, sorghum, grows well with low water availability, but the yield can be greatly affected by drought conditions.

Pabuayon and the TTU team found that even under conditions that lowered sorghum and cotton yields, sesame performed well. This could be good news for west Texas farmers.

Having another crop that has good market value and can grow well during drought could benefit west Texas farmers. According to Pabuayon, sesame seeds are commonly used for food consumption and other culinary uses. The seeds are high in fat and are a good source of protein. Sesame is a major source of cooking oil. The remaining parts of sesame, after oil extraction, are good sources of livestock feed. Sesame has uses in the biodiesel industry, and even in cosmetics. This means there are multiple markets for the tiny seeds.
