Onions respond favorably to increasing levels of soil moisture as measured by increase in bulb size and total yields. Maintaining a soil moisture level of 18-20 centibars of tension (nearly field-holding capacity) produces the greatest yields of bulbs. However, dry onions so produced are somewhat softer in texture, tended toward thick -neck growth, matured slower, and are more difficult to cure adequately in the normal length of time. Onions grown on lesser amounts of water tend to have the reverse characteristics. Costs of production are similarly increased under high soil moisture levels because of the need for replacing nitrogen leached out of the root zone. Also, the costs of the water and its application must be increased. Therefore, the economics involved would be a required consideration.
