Planting split rows, or the practice of adding row units between existing row units to plant narrow row soybeans, has been around for nearly 40 years. Originally introduced by Kinze Manufacturing, Inc. in 1978, split rows were initially achieved by installing row units side-by-side on Kinze rear fold frame planters. In 1983, Kinze introduced its unique, patented push row units, which were installed on the front of double frame toolbars, that enabled a single planter to be easily used for both corn and soybeans. The introduction of this innovative feature, and its incorporation as a common farming practice, provided farmers with trash flow and yield advantages.
Trash Flow Advantages
Kinze’s exclusive push row units have better trash flow and seed placement accuracy than other narrow row planters:
- The 16” spacing between parallel toolbars creates additional clearance between row units to allow trash to flow freely when planting in heavy residue
- Split row design plants 15” no-till soybeans between the previous season’s corn stalks to optimize stand counts and minimize tire tread wear
- Push row units are easily raised and locked when using the planter for 30” corn
- Uncluttered double toolbar design allows for additional options, like bulk fill or fertilizer, without sacrificing capacity
Yield and Profit Advantages
When split rows were introduced and planters, instead of drills, began to be used to plant soybeans, improvements in yields were soon realized. In 2016, Beck's Hybrids published the results of a 10-year, multi-location seeding rate study. The study clearly shows the yield and profit advantages of planting soybeans at 15” spacing instead of 30”.

In addition to increased yields, using a narrow row, no-till planter has many other direct and indirect economic advantages:
- Excellent soil erosion control
- Soil moisture control
- Reduced fuel and labor costs
- Builds soil structure and health
- One planter can be used to plant multiple crops
