I have similar data and formulas for the other three varieties. In the end, of the 318.7 pounds that I started with (I did not count the TF mongrel variety which were all too small to plant), I put 190.9 pounds into the ground (we also reserved about 2 pounds of each variety to take pictures). This comes out to about 30 minutes of labor per pound. There is no doubt that I could have planted more quickly with more efficient equipment, but that kind of equipment costs money. I will need to do careful analysis to figure out if and when it makes sense to invest in better equipment. In the end, it may be better to just hire more labor and use the same relatively inefficient methods. I'm certainly in no hurry to take on debt for machinery.
