New soybean topping technique for higher yields: operate this way to get a bigger harvest

Soybean terminal buds have strong growth vigor and consume a lot of nutrients. Removing the terminal buds of soybean transfers nutrients to the pods, which helps increase yield. This is especially true for soybean with higher soil fertility and vigorous growth; timely removal of the terminal buds makes the yield-increasing effect even more pronounced.

The method for removing soybean terminal buds is: at the early flowering stage, the peak of soybean growth, pinch off the 2-3 cm tender tip at the top of the main stem, so that apical growth is inhibited and nutrients are concentrated for reproductive growth, promoting more flowering and more pod setting, and helping to make the plants shorter and sturdier and enhance stress resistance.

Soybean topping should follow the “three suitable” and “three unsuitable” rules: suitable early rather than late, and it should be done before full bloom; do not top after flowering. Suitable for fertile conditions rather than poor ones: plants with good water and fertilizer, high fertility and vigorous growth can be topped; otherwise, they should not be topped. Suitable for sparse planting rather than dense planting: do not top plants that are growing densely; for sparsely planted soybean and vigorously growing plants, the terminal buds should be removed at the right time, as this helps increase yield.

When soybean is flowering, spraying 0.05%-0.1% molybdenum fertilizer at the right time and in the right amount has a clear yield-increasing effect.
