The proper and standardized use of plant growth regulators to control excessive vegetative growth and promote pegging in peanuts can indeed lead to higher yields—characterized by more pods and fuller kernels. However, precise timing, the selection of the right product, and scientific application methods are essential to avoid adverse effects.
Key Functions and Yield-Boosting Effects
Regulating Nutrient Allocation:Inhibits excessive stem and leaf growth, reduces the waste of nutrients on non-productive parts, and directs more photosynthetic products toward pegs and pods, thereby preventing an imbalance between vegetative and reproductive growth.
Promoting Pegging and Pod Formation:Shortens internode lengths, resulting in a more compact plant stature and improved lodging resistance; simultaneously significantly increases the rate of peg penetration into the soil and the number of productive pods.
Enhancing Kernel Fullness:Promotes pod expansion and development while reducing the proportion of empty shells and shriveled pods. Field tests show that proper application can increase peanut yields by 10%–20%, with even higher increases observed in well-managed plots.
