Synopsis

Reductions in yield due to 3 rates of plant removal (15, 30, and 45%) at 3 stages of plant growth were relatively small. Greatest reduction in yield occurred when plants were removed about 2 weeks after bloom with progressively less reduction being evident at the peak blooming period and about 2 weeks before bloom! An increased number of pods per plant appeared to be the component of yield primarily responsible for this compensation.
