Acre Feet Of Water To Grow Corn

The kernels are sweet and can be preserved easily.

Acre feet of water to grow corn.

Let s assume 9 inches will be applied and 65 bushels per acre acre will be produced. Trout found that corn yields varied from 210 bushels for a full application of water down to 130 bushels for the lowest irrigation level. To that you must add a component of water for leaching and an adjustment for air temperature. There are roughly 27 000 gallons of water in an acre inch.

Water an area 2 feet in diameter around the base of each plant and apply. Lai increases to over 5 0 under fully irrigated corn with plant populations above 24 000 plants per acre. By the time that corn reaches tassel emergence the plant has achieved 100 percent all of its effective rooting of about 3 feet. The evaporative transpiration quotient for any crop is different but known.

That equates to 1 pound of corn for each 60 gallons of water absorbed. Root depth increases from 18 inches to 4 feet during this period doubling the amount of soil water available for plant growth. 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. Statewide irrigated corn yields have averaged 184 bushels acre but yields of 220 bushels acre are not uncommon.

Irrigations that follow cultivation can also result in heavy applications of water. 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. 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. It is common that 6 9 inches or more can be applied in a pre irrigation event.

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. The stalks reach 6 feet in height. Here is a winning variety that is triple sweet with a rich flavor that you ll love. Soybeans can be stressed somewhat more and require less water.

Water use rates grow to 0 32 inches per day when averaged over a three to five day period. Non irrigated corn yields averaged 113 bushels acre during this same period. This variety of corn produces large ears that measure 9 inches long with bright yellow kernels. 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.

In a much more general sense most row and tree crops take about 3 5 acre feet per acre. This amounts to 1 705 gallons of water per bushel of corn produced. A major challenge is to limit the. Grain takes less and forages take more.

Therefore 325 000 gallons of water are pumped per acre to produce the crop.
