Fellow food plot buddy of mine gave me some approx 4-5 yr old sugar beet seed from Welter Seed Co. I did a germination test and see if they were viable. Turns out I got about 60% germination, so I gave them a try in a small experiment. One of my 3 plots is a 1/3 acre plot that has been planted 4 years now. Each year I have added pelletized lime and the appropriate fertilizer according to soil sample tests.
I specifically amended the soil with pelletized lime and DAP (diammonium phosphate) fertilizer at the exact levels the soil test required for growing sugar beets. No potassium was required. Also put the appropriate amount of boron required. The plan was 11 rows, 1' apart & 50' long or about 550 sqft. knowing the 60% germination I planted the seeds pretty close, which you will see in the pics. I planted them on 5/27/17 and at the same time planted the remainder of the 1/3 acre in winter rye and soybeans. Below are pictures at different dates so you can see how fast (or sloooow) these sugarbabies grow
5/27/17 - Tilled in Lime, DAP and Boron and Planted. Remainder was planted in winter rye and soybeans.
6/8/17 Sprouted
6/11/17 I built a fence to keep the honest out, hoping the deer would prefer the young winter rye and soybeans.
6/18/17 - Winter rye and soybeans growing well and sugarbeets are growing ok

6/24/17 - Sugarbeets put on some growth in the past week. I thinned but not to the recommended 1' spacing.
