Abstract
This research was conducted to evaluate the effects of the planting systems and lime dosages on the corn and forage (Urochloa brizantha) yield, the weed control system and soil seed bank of the corn-forage intercropping system. The experiment was conducted under field conditions in a randomized complete block design, with four replications. We adopted a split plot 2×4 arrangement, consisting of a combination of two planting systems (tillage and no-tillage) as plots with four lime doses (0, 0.83, 1.25 and 2.50 t ha 1 ) as the subplot. Maximum plant height, stem diameter, dry matter and corn yield were recorded in the no-tillage system, with 311% higher productivity in the no-tillage system compared with the conventional system, regardless of the limestone application. The high production is mainly due to the ability of the no-tillage to retain and provide the corn plants with water. The results showed that liming influenced only the corn grown in the conventional system. Weed infestation was higher in the non-tillage system whereas, the tillage system enabled greater diversity and quantity of viable seeds in the soil. The no-tillage is, therefore, an excellent alternative to the intercropping corn-forage production during the late summer cultivation.
