Within our garden we have a section called the 40 Bed Unit. This is our experimental area that represents all the food, compost crops, etc. grown to sustain one person. This is the area where Randy and most of the interns have grown their experimental beds. Within these beds we have grown 740 square feet of potatoes. All of our potatoes have exceeded or almost equaled the national average. Our average Yukon Gold yield was 83 lbs/ 100 sq. ft.; Yellow Finn was 92 lbs/100 sq. ft; Rio Grande russets was 95 lbs/100 sq. ft; and Colorado Rose was 112 lbs/100 sq. ft. Our seed potatoes came from Sanhedrin Nursery in Willits and they’re a wonderful organic seed potato from White Mountain Farms in southern Colorado.
The other crop that we have some data on at this time is our quinoa. We have 200 square feet (out of more than 500 sq. ft.) threshed and winnowed. The variety we have grown this year is Colorado 407D. This is the third year we have grown this variety in our garden. It is extremely beautiful and grows quickly and quite well in our shorter growing season. Quinoa, in general, likes cooler drier weather. Some of the quinoa that was planted at the end of April and the first part of May was smaller and more affected by fungus because of the wet weather. While it still grew, the yields were decreased somewhat from what we were used to producing. We have an average, at this point, of 8.3 lbs/100 sq. ft. with a biomass yield of 7-8 lbs/100 sq. ft. In past years, with this variety, we have achieved 10-11 lbs/100 sq. ft with a biomass yield of 8-9 lbs/100 sq. ft. We expect that the quinoa that is not yet threshed will exceed our existing average. Those that were planted at a later, warmer and drier time didn’t develop the fungus that seemed to affect the growth of the earlier quinoa.
We have had great success in past years growing this particular variety of quinoa as a catch crop. Catch crops are crops that you plant after over-wintering or early spring planted crops come out of the garden beds in late June or July, like cereal grains or garlic. Catch crops are quick growing plants that will produce food or biomass for compost before it is time to plant the cover crops for over winter. We were able to grow a crop of quinoa that produced well from early July to early October.
We are growing a beautiful variety of purple amaranth that we found last year from Canada. It is a combination of many colors and shapes that are quite vibrant and white-seeded. We have been able to grow seed from the amaranth as a catch crop this year, and the biomass from the amaranth is quite a bit larger and fuller than the amaranth that we transplanted in the cooler, wetter months. Amaranth is a heat-loving crop and is quite beautiful in your garden.
