Environmental Factors in Potato Crops
- Other similar tests have of course been conducted since the 1940s. In 1990 the Canadian Journal of Plant Science published a paper called ‘The Effect of Flower Removal on Potato Tuber Yield’ [1]. Their results were mixed with one test mirroring the increased yield of Minnesota, and another mirroring my own. Their conclusion? ‘Response to flower removal appears to be dependent on e…
But Should You Remove Potato Flowers Or Not?
- If you have the time to remove potato plant flowers on maincrop varieties then do so yes. Since the evidence is that it either boosts yield, or does not boost yield, but it certainly doesn’t reduce yield. So you have nothing to lose by taking them off. In any case, you don’t really want lots of tiny green toxic potato berries growing on your plot l...
