First off thanks for the help.
I will not have to worry too much about droughts here. This year we had a really bad drought, but we still got very high yields.
We irrigate our fields like crazy. It does not matter if you don't get an inch of rain in the whole year, because we have a nearly unlimited amount of water underground. The agricultural wells are shallow, and refill as fast as we can pump.
Heavy rain fall might be an issue here. how does it kill the plants? does it drown them, or does it break the leafs?
Also if it gets hot, but it has enough water will the plant do fine? Some years we average about 95f top temp in the summer, but others we go 105-110 very often. Most years we go close to breaking, or break 100 everyday in the mid summer.
Also during certain times of the year we have high winds, and tornadoes.
The other thing that have to worry about is crop dusters. I will try to put my plot in the corner that does not back up aginst farm fields.
