May planted Radish Plot final results 8/4/2010

GroundHog Radish consistently had the larger and deeper tuber of all varieties tested. This photo is from the ~5#.acre seeding rate plot.

This photo shows the GroundHog Radishes dug from the ~12-15#/acre rate plot. Note how much smaller the tubers are than the 5#/acre rate.

It’s been 10 1/2 weeks since I planted my Radish test plot in my garden.  I have recorded photos and reports in previous posts and now this is the “FINAL JUDGMENT” of the different varieties that were included this spring.  I’ll report mainly via photos and captions.  Just a reminder, about 5 weeks ago I thinned out plots of each variety so I’d reflect 2 different seeding rates; ~5#/acre, and ~12-15#/acre.  The goal was to see if seeding rates matter and also if we can use fewer radishes and still accomplish great results.

I’ll be planting another radish plot in a week or so to see how a mid-summer planting plots might differ.  I’ll also add some of the other popular varieties/brands and two more experimental varieties folks are sending for us to test.

This variety had the single largest radish...but only the one radish was of any size. This was from the ~5#/acre plot.

This is from the ~12-15#/acre plot area. One of the radishes was of good size but the others were quite small when compared to GroundHog.

I don't know how to say I'm disappointed in a variety...but this one sure surprised me. At first I called it "stubby". Later I found it "intriguing" because it had such a long skinny tap root. Now I call it "disappointing". I was anticipating lots of long skinny roots 15" deep or so...and all I got was what you see above. This is from the ~5#/acre rate plot.

You can see big differences in these two varieties both shown at the ~5#/acre rate.

This variety was one that I pegged early as one I thought would be the "best" radish. Needless to say, I was wrong. This is from the ~5#/acre plot.

Columbia from the ~12-15#/acre plot.

    What do you think?
    very good plot. this mirrors what I have seen the past 3 yrs. in my plots. I had come to the conclusion that 3-5 #/ a is the optimum rate for root size. I have also seen that too many other species planted in combination also reduced root size.
