Do corn plants need a lot of water?
High yielding corn requires approximately 22 to 30 inches of water per year depending on planting date, planting density, maturity group, location, and weather conditions. Corn requires the most water during the early reproductive growth stages (Table 1), which are also the most sensitive stages to water stress.
When should you stop watering corn?
A good rule of thumb is to maintain a good soil moisture profile until the starch/milk line on the kernel reaches the 50-75% mark (which is about half way down the kernel ~ see photos below). Pick about six ears from different locations in the field, break the ears in half and pull kernels from the middle of the ear.
Why is my corn plant leaves turning yellow?
Yellowing corn leaves are most probably an indicator that the crop is deficient in some nutrient, usually nitrogen. Corn is a grass and grass thrives on nitrogen. The plant moves nitrogen up the stalk so a nitrogen deficiency manifests itself as corn leaves turning yellow at the base of the plant.
How much water does corn use per day?
Daily corn water use averages between 0.15 and 0.20 inches per day (Table I). The plant’s roots are concentrated in the top 18 inches of soil if there are no soil-limiting factors such as compaction, impermeable layer, or gravel.
