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.

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. It only reaches 5 feet tall but since it bears corn fast it s worth it. Soybeans can be stressed somewhat more and require less water. 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.

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. By the time that corn reaches tassel emergence the plant has achieved 100 percent all of its effective rooting of about 3 feet. It is common that 6 9 inches or more can be applied in a pre irrigation event. In the first three years of research each acre of land in the study produced about 10 bushels of corn for each inch of water consumed.

Root depth increases from 18 inches to 4 feet during this period doubling the amount of soil water available for plant growth. Irrigations that follow cultivation can also result in heavy applications of water. In a much more general sense most row and tree crops take about 3 5 acre feet per acre. Let s assume 9 inches will be applied and 65 bushels per acre acre will be produced.

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. Therefore 325 000 gallons of water are pumped per acre to produce the crop. Here is a winning variety that is triple sweet with a rich flavor that you ll love. 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.

Statewide irrigated corn yields have averaged 184 bushels acre but yields of 220 bushels acre are not uncommon. Water use rates grow to 0 32 inches per day when averaged over a three to five day period. The kernels are sweet and can be preserved easily. This amounts to 1 705 gallons of water per bushel of corn produced.

Lai increases to over 5 0 under fully irrigated corn with plant populations above 24 000 plants per acre. The stalks reach 6 feet in height. A major challenge is to limit the. Grain takes less and forages take more.

That equates to 1 pound of corn for each 60 gallons of water absorbed. This variety of corn produces large ears that measure 9 inches long with bright yellow kernels. The evaporative transpiration quotient for any crop is different but known. To that you must add a component of water for leaching and an adjustment for air temperature.

Non irrigated corn yields averaged 113 bushels acre during this same period.
