Requirements for Grain Sorghum Irrigation on the High Plains


Book Description

Irrigation research was conducted with grain sorghum on the optimum use of underground water resources at the Amarillo and Lubbock Experiment Station and on off-station plots during the past several years. Highest returns in pounds of grain per inch of water are received when grain sorghum is supplied with adequate moisture from planting to the soft dough stage. High-moisture levels are the most profitable; if the irrigation water supply becomes inadequate, the acreage to which water is applied shoud be reduced. A grain sorghum crop can be produced with a preplanting irrigation alone in very dry years when dryland crops are complete failures. Nitrogen fertilizers can be used to advantage with proper water management and will provide yeilds of 5,000 pounds or more of grain per acre.
