I will be honest James, I had a heck of a time with pests until I learned to work with the moisture cycles. It was three to four years before I understood and began to work with my local moisture cycles.
You see at first, I followed the directions on the corn packets, which told me when to plant in my "zone." This was total disaster as the rats and
mice ate the corn as it was emerging. I came out one morning to see my corn emerging from the ground, about an inch tall, only to return the next morning to find it eaten to the ground. It would make one last valiant attempt for emergence- and the rats would return again. Not one corn plant made it that first year. But I found the concept so intriguing, that I just had to know how the Indians outsmarted the rats. I realized what was happening is that the rats (desert rats) and mice were eating the corn shoots for their moisture- not their calorie content.
Understanding that it was moisture the pests were after, I did some more research into when the Indians planted, for they certainly had no issues with their harvests! Turned out I was planting far too late. The rats and mice were starving for moisture at that point and would eat any green thing they could find.
Next time I planted in late March, with emergence in early to mid April. This is exactly the same time as the Spring rains and there's lots of moisture for the rats and mice from other sources. They actually don't seem to bother the corn in the least at this time of year, apparently it's not a prefered crop for them.
All deserts with the exception of maybe the most harsh, have some sort of moisture cycle. In Arizona, we can get quite a bit of rain, but it all comes in droves- then waits another nine months before raining again!
I suspect Israel and the surrounding regions are much the same. If I were going to teach you to use this method, I would first test your moisture vault during the driest months, (most likely now) by digging a hole. Odds are good the top is like digging through
concrete, but somewhere between two to four inches, you will will suddenly notice a difference in the earth. It will become far softer, cooler and loose. The hard soil is the vault door and the soft soil is the moisture vault. You want to plant down to this level, so the roots will always have a moisture source. I find that a four inch trench depth along with a two inch corn planting in the lowest part of the trench, seems to be a near universal.
I would start small scale, maybe four trenches six feet or so in length. They can be made by hand if they are not longer than six feet. Dig down about four inches, then plant your seed two inches deep in the middle of the trench. I actually found the corn grew better if each seed was planted six inches from the other. I thought such a method would stress the moisture vault too much, but I was looking for limits anyway. The serendipitous surprise was that closer plantings cause each seed to grow faster. I suspect that each plant is much like the average person and very much wants to keep up with the Jones's! I also noticed, though I can't prove it, that the corn took on a symbiotic nature when planted this close. It seemed to grow as one, pollinate as one and bare fruit as one. How a simple corn plant knows what it's neighbors are up to is beyond me, but I am convinced that they do! So while it sounds like it's a great way to stress the plants and the soil, they actually grow far better close together at a six inches apart, than a foot or eight inches. (Tried both of those too, not as good a result as six inches apart.) The other thing I noticed, to my amazement, was that denser corn creates it's own atmosphere! My dogs first clued me to this, when they would disappear into the fields during the hottest part of the day. They would emergence later, not panting or thirsty and looking well rested. Puzzled, I crawled in with one and sat down. WOW, was I shocked! Had to be 70 degrees Fahrenheit with about 60% humidity! (At a typical daytime temperature of 110 Fahrenheit.) It was a literal oasis in the middle of one of the most brutal deserts known to man. So pack the corn in tight and don't worry about overcrowding. Corn likes it's neighbors. This is born out by my observations here in North Dakota. Farmers corn fields are always stunted around the edges. But one level in, the corn thrives.
I would suspect that the traditional Indian planting date of April 15th is a near universal. All frost is gone by that time in deserts, (usually) and it is a peak "wet time" for most deserts and semi-arid lands.
Another tip on keeping corn from pests is the use of what I call "corn dogs." I had five dogs during this time. (My wife is a serial rescuer, lol) They worked as a team to keep the corn pest free. They naturally love to hunt and any four legged pest deciding it wanted my corn risked its life running the gauntlet of my "corn dogs." Best breed so far was and is a Springer Spaniel. Wonderful dog, she would hunt all day in the hot sun, flopping into a pool of water for about 60 seconds and then back on it. All the other dogs would watch her from the corn field, then jump up and pursue whatever she had scared up. (She use to point grasshoppers too- wish I had a video!)
The small loss in crushed corn was minor. The dogs seem to stay atop the mounds, avoiding the trenches. Only a few corn stalks were ever destroyed- certainly worth it for day and night pest control. Even had a dog that ate rattlesnakes. He was immune to their venom after his second bite. Each dog had a "snake bark" that was a call to the "Guy" the "snake killer." Guy would come running to that bark. Before I could even realize what was happening, he was there and engaging in combat with rattle snakes. (We had really nasty Mohave Greens by the way.) He would grab the snake mid section, thrash his head back and forth with the snake in his mouth and then fling the snake 15 feet or more in the air. He would then run like hell! The poor snake would come down in pile, too stunned to defend itself. Guy was then all over it.
It's truly amazing how all these disparate intelligences come together on a farm. There is a rhythm, an unspoken understanding, a collective intelligence if you will that all starts with an understanding of the land, the weather and the natural cycles. It was a great time and place and I hope to return to it sooner, rather than later.
