Big, tall plant with awesome yield punch! Very high demand silage product that also delivers top yields with incredible test weight.


Sensitive to late dicamba applications. Only average tolerance to Goss’s wilt.


We had been using the SmartStax® version of this hybrid (H4724) for a year but the VT Double PRO® RIB Complete® version delivers more yield and has enhanced tolerance to anthracnose stalk rot. It was an easy switch! Push this hybrid for top yields with fertility early for ear and plant development and late for heavy test weight.


The higher the number, the better the performance or rating.

This year’s corn (Hefty 4732) is looking really good, we are seeing good emergence and stand-ability in our fields, and they’re looking even.
