R3 Stage: Beginning Pod Development
When 1 pod on 1 of the 4 upper nodes reaches 3/16" long, the plant is at R3. This usually occurs between V11 and V17. Plants are 23" to 32" tall. Typically, 60% to 75% of flowers abort, but stress can increase the loss. Temperature or moisture stress can limit pod numbers, beans per pod or bean size. Because of its long flowering period, the plant can compensate some for losses, but its ability to make up ground dwindles as it approaches R5.
