Effect of tillage system on growth, maturity and yield of corn and soybean

Entry ID: PU.Agronomy.TillageSystem

[ Update this Record ]

Summary

Abstract: This experiment was initiated in 1976. In the previous years
(1955-1975), the site had corn/soybean production with annual
moldboard ploughing. It is estimated that between 1880-1955 there
was mixed forage/grain production, ploughed two years in every five.
Before 1880 the site was in native prairie
grass.

Rotations used in this experiment are continuous ...

GROUND-BASED OBSERVATIONS

Quality There are at least 4 replicates in the experiment. The experiment has
a restricted randomized plot design. Split plot design with crop
rotation as main plot and tillage system as subplot. There are control
plots described as follows: Fall moldboard ploughing, most common
practice on this soil for the previous 100 years, was included as a
control. Yield data was analysed using Student-Newman-Keuls test and
coefficient of variation. Years was included as a fixed variable.
