However, we could see as population decreased we saw an increase in both number of branches and number of nodes. Then we had to hypothesize if an increase of 12.9 nodes per plant was enough to overcome the loss of 90,000 plants per acre. We were very confident in the 80,000 and 100,000 plant populations at that time. At harvest we were excited to see that yields did not vary a lot between populations. The 120K population had the highest yield and the 80K had the lowest yield (there goes our theory).
