A COMPARISON OF THE MOLD BOARD PLOW AND THE ROTO TILLER WHEN USED AS SPRING TILLAGE IMPLEMENTS FOR THE PRODUCTION OF CORN AND WHEAT IN A TWO YEAR ROTATION.

This trial compares the production of corn and wheat, in a two year rotation, planted following spring tillage with the roto-tiller, and production of corn and wheat planted following spring tillage with the moldboard plow.

Yields are recorded in table 34.
