Acre Feet Of Water To Grow Corn

Trout found that corn yields varied from 210 bushels for a full application of water down to 130 bushels for the lowest irrigation level.

Acre feet of water to grow corn.

Root depth increases from 18 inches to 4 feet during this period doubling the amount of soil water available for plant growth. A major challenge is to limit the. The kernels are sweet and can be preserved easily. Non irrigated corn yields averaged 113 bushels acre during this same period.

In a soil that holds 1 inch of water per foot this would wet the soil to 6 9 feet much deeper than corn roots will effectively take up water. Water use rates grow to 0 32 inches per day when averaged over a three to five day period. By the time that corn reaches tassel emergence the plant has achieved 100 percent all of its effective rooting of about 3 feet. Let s assume 9 inches will be applied and 65 bushels per acre acre will be produced.

To that you must add a component of water for leaching and an adjustment for air temperature. It only reaches 5 feet tall but since it bears corn fast it s worth it. The stalks reach 6 feet in height. This amounts to 1 705 gallons of water per bushel of corn produced.

Irrigations that follow cultivation can also result in heavy applications of water. A 3 foot deep reservoir of soil moisture can hold as little as 3 inches on sands to as much as 6 inches on loam soils. The us nationwide average corn yields are grain 150 bushels per acre or 4 2 us tons per acresilage forage 21 us tons per acreyields can vary quite a bit by state location and year. This variety of corn produces large ears that measure 9 inches long with bright yellow kernels.

Water an area 2 feet in diameter around the base of each plant and apply. That equates to 1 pound of corn for each 60 gallons of water absorbed. Therefore 325 000 gallons of water are pumped per acre to produce the crop. Grain takes less and forages take more.

It is common that 6 9 inches or more can be applied in a pre irrigation event. Here is a winning variety that is triple sweet with a rich flavor that you ll love. Between the 8 leaf stage and tassel emergence corn root depth leaf area and water use grow rapidly reaching peak daily water use rates during pollination. Plants are usually small at this stage and their root development limited resulting in much of the water applied not being available to the plants.

The evaporative transpiration quotient for any crop is different but known. Water sweet corn in the morning once a week if there are no heavy downpours giving each plant 1 to 1 1 2 inches of water. Lai increases to over 5 0 under fully irrigated corn with plant populations above 24 000 plants per acre. Soybeans can be stressed somewhat more and require less water.

In a much more general sense most row and tree crops take about 3 5 acre feet per acre.
