Maize intercropped with legumes may be an interesting alternative to increase yield and quality of silage, improving the use of agricultural areas. The objective of this work was to evaluate the fodder yield and the crude protein and mineral matter content of corn silage, cultivated in monoculture and intercrop with legumes in different arrangements between rows. Experiment was carried out at the Universidade Tecnológica Federal do Paraná (UTFPR) campus Dois Vizinhos, adopting the experimental design of random blocks following a 4 + 1 x 2 factorial scheme, with three repetitions. The first factor is regarding to intercropped species (Cajanus cajan, Crotalaria juncea, Dolichos lablab and Mucuna aterrima) plus single corn; and the second factor being the arrangements between rows (45 cm spacing between corn row with single row of the legume species and 90 cm spacing between corn row with double row of the legume species). There was a reduction of 6,508, 5,600 and 3,663 kg ha-1 in the yield of corn silage for the intercropped treatments with mucuna, labe-labe and crotalaria respectively, in relation to the corn monocrop. However, total silage yield (kg MS ha-1) did not differ statistically when comparing the different species consortium and the corn cultivated in monoculture. It is highlight the lower interference of guandu at the intercrop, showing similar corn silage yield in relation to the monocrop of the cereal. Silage crude protein was higher at the intercrop in relation to the monocrop of corn due to the use of leguminous plants. Especially the intercropped with crotalaria produced 440 kg PB ha-1 more than the cultivation of single corn, being the best alternative to increase the production of crude protein per unit area. Further studies related to the animal performance are fundamental to increase de adoption of intercropped systems. |
