The Whitetail Institute’s Imperial Power Plant is a variety of warm season annuals, including soybeans, cow peas, lablab, sorghum and sunflowers. With the promise of “more tonnage per acre than any other spring/summer annuals”, Power Plant was on my list of food plot seed to try in the spring of 2010.
Sunflowers and sorghum are not something you would normally plant for deer, but there is a method behind the madness. The sunflowers and sorghum actually provide structure for the legumes to grow up and around. This keeps the legumes from growing along the ground and possibly stunting their growth.
In addition we also release quail on our farm, so the sorghum can provide them some nutrition in the colder months ahead.
The Whitetail Institute recommends planting Power Plant once the soil temperatures in your region reach at least a constant 55-60 degrees. The main reason is that soybeans have much greater success when planted at this temperature.
They also recommend a soil PH of 7, disking the area at least 4-6 inches deep, and disking lightly after broadcast-spreading the seed.
NOTE: We spray our warm season annual plots with 41% glyphosate early in the spring well in advanced of planting. It takes 10-14 days for the glyphosate to do its job and be safe for planting. We also lime and fertilize based on the PH of the soil and the recommendations for the seed we are planting.
How We Planted It
There were two food plots in which we planted Power Plant. In the last week of May, we had some pretty warm temperatures here in Virginia and the soil temperature was right at 55. The decision was made to plant the first food plot.
This plot is the largest, around ¾ of an acre, fairly rocky and slightly sloped. The PH was right around 7 and the soil was fairly easy to disk up because we had tilled it the year before. We removed the larger rocks by hand and we ended up with a pretty clean bed.
We decided to try something new with this plot, so we only planted Power Plant around the perimeter. The intention was to use Power Plant’s sorghum and sun flowers as cover for the deer as they munched on the Imperial Clover that we planted in the middle.
We decided to wait a couple of weeks before planting the second food plot, which is about ¼ of an acre. This was to test the difference that soil temperature would make as well as hedge our bets with the weather. The plot had a slightly lower PH, was level to sloping, and was less rocky than the first plot. The entire plot was planted in Power Plant.
