The following study was conducted by Beck’s Hybrids as part of their Beck’s 2015 Practical Farm Research Book, with a stated mission to “Our mission is to provide you with the best farmer focused research and advisors to add profitability to the farm.”
The results show a combination of 2015 results from their research plots as well as historical data since we all know that one year of data does not always repeat itself but over 3-4 years the best methods tend to prove themselves out. As you can see, they have proven a significant advantage to side-dress with coulter injection from V3-V6 time period. Consistently, we can see that this application method and timing either through split application or 100% early season side-dress (V3-V6) beats out 100% pre-plant nitrogen applications and also significantly out-preforms late season side-dress application with high clearance equipment.
