Abstract

The productivity of corn in the Amazonas is low when compared to other states in Brazil. Thus, the low natural soil fertility and the limited adoption of sustainable technologies are responsible for the low yields. Vegetative cover crops have been shown to be an excellent alternative in sustainable management. This study aimed to evaluate the biometric parameters of corn plants subjected to intercropping with different cover crops. The experiment was conducted at the experimental farm of the Federal University of Amazonas. The experimental design was a randomized block in a 5x5 factorial scheme, with four species of cover crops (Brachiaria ruziziensis, Vigna unguiculata (L.) Walp, Canavalia ensiformis (L.), Mucuna pruriens) and a control treatment (without cover crop), and five sampling periods: 14, 28, 42, 52, and 70 days after emergence (DAE), totaling 25 treatments with 5 replications. The following parameters were evaluated: plant height, corn stalk diameter, leaf area, total dry matter weight (root, stalk, and leaves), and leaf area index. Up to 70 DAE (vegetative stage), the cover crops of Brachiaria ruziziensis and Vigna unguiculata (L.) showed better vegetative performance of the corn plants.

Key Words: Green manures, vegetative stage, Amazônia.
