Description
The aim of this work is to evaluate the root activity patterns of three forage graminaceous species under different tillage systems. The field experiment was carried out during 1993-94 in a Mollisol under three tillage systems: plowing, chiseling tillage and subsoiling tillage system cultivated with Lolium multiflorum, Bromus catharticus and Phalaris aquatica. Significant differences were found in lateral root distribution between tillage systems. Subsoiling tillage system treatment showed the largest presence of roots at 10 cm lateral distance from the plants. No differences in root activity at 10, 20, and 30 cm from the plant were found in chiseling tillage treatment. Plowing treatment showed a higher root activity in the first 20 cm from the plant. The total root activity was the highest in subsoiling treatment and significantly different from chiseling and plowing tillage systems.
