Soybean Growth & Development

• Early Season Soybean Leaf Malformation

Vegetative growth stages in soybean are numbered according to how many fully-developed trifoliate leaves are present. The reproductive stages begin at flowering (R1-R2) and include pod development (R3-R4), seed development (R5-R6), and plant maturation (R7-R8). Growth stages can overlap. Determine the growth stage of a crop when 50% or more of the plants are in or beyond that growth stage in question.

• R3-R4 Yield Components of Soybean during Pod Development
• R5-R6 Yield Components of Soybean during Seed Development
• R7-R8 Yield Components of Soybean during Maturity
