Sesame yields stable in drought conditions

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.
