Drought effects nut fill
This morning, I cut open some nuts to check on the progress of nut filling and made some interesting observations. The first cultivar I checked was Pawnee. I had expected Pawnee to have nut filling problems this year because of its large nut size but was pleasantly surprised when I found a fairly well packed kernel. However, our Pawnee nuts will not be perfect. In an earlier post, I mentioned that kernel filling starts at the seed coat and works inward. Note that the top of each kernel half has grown much thicker than underside of the kernel. This will mean that, at harvest, our Pawnee nuts will have a concave appearance on the bottom of each kernel half.
