Need assistance with a serious project!!!?

Question

I'm working on an agricultural project and i just need help on the following. I would like to know the appropriate irrigation system for maize production on a large scale. May you please define efficient farming too.

Answer 1

To properly grow maize (corn) it should be grown in areas that have sufficient rainfall.  So the answer would be rain...from the sky.

Efficient farming?  That is going to have VERY differnt meansing to different types of farmers.  I sugest you look up the words layer farming, permaculture, mono crops, and factory farming to see just HOW different "efficient " farming is to different types of farmers.

Answer 2

Everything is dependent on location of the farm. The right answer to irrigation problems in one place/ farm are completely different on another farm, close together in locations or in vastly different locations. Look at all the different types of irrigation and THEN fit them to different areas on this planet. The ways we move water to our crops is an answer to the problem of providing water when nature doesn't cooperate. I think if you look at it from that point of view it will make your project easier. Look at different ways of irrigation as a tool for cropping in certain environments and conditions. Then you can get specific with the crop, generally secondary in consideration. Efficiency in this case would be to provide adequate water resources as inexpensively as possible with respect to availability keeping in mind that there needs to be, built into the system a way to increase production, to grow, and resources need to keep in line with that.

Answer 3

Corn has traditionally been grown where there is enough rain. When there is too little rain, so that irrigation is needed, corn is a low profit crop compared to many that could be grown.

Corn has a virtue that it puts its roots down deep into the soil to retrieve water when it is in short supply. We could still grow corn on land that has been irrigated to provide say 50 to 150 cm of water. But if you were irrigating you might choose instead to grow rice or millet, vegetables, fruit or nut trees.

The reason for growing corn at all is to cash in on a government price support, with methods that allow one to farm large numbers of hectares of land with little manpower.

Yes, corn has been used to produce ethanol, but corn is not the ideal crop for that. It has been used because there have been large surpluses of corn.

Corn is often grown on land that is rolling, so keeping irrigation water where you put it is problematic but not impossible. Corn fields are mostly exposed soil so that irrigation presents problems with soil eroding or baking hard.

We have to be careful in many areas lest irrigation water, applied in excess, may disturb salts, causing it to wash down over lower growing areas, killing them. This is true for any crop grown with irrigation.

Efficient farming is often getting the most product one can consistently get with available water, with optimum levels of nutrients, and still keep costs of machinery, buildings, and labor low.

Failing to use some available water may still be efficient, if using it might leave aquifers or storage reserves low for  a future period.

Optimum levels of plant nutrients is not a fixed number, and is dependent on cost and availability. Costs of labor and machinery often work in opposition. Ever so many farms have failed because of too much investment in machinery.
