Texas AgriLife Research scientists have recently completed a two-year study on the impact of deficit irrigation and plant density on the growth, yield and quality of short-day onions.

Defecit irrigation is a strategy in which water is applied to a crop during its drought-senstitive stages of development and is either applied sparingly or not at all during other growth stages, particularly if there is sufficient rainfall, reducing the overall amount of irrigation through the crop cycle.

According to crop production experts, the strategy is particularly helpful in areas where water limitations or restrictions are a significant factor.
