| Summary: | The intercropping has been shown as effective cultivation technique to rise the production from the simultaneous cultivation of different species in the same area. Thus, the objective of this research was to evaluate, in off-season cultivation, the forage and grains production in off-season by interrow intercropping of grain sorghum with brachiaria in two sowing depths. The experiment was carried out in field in Rio Verde-GO, on March 5, 2009. The experimental design used was the randomized blocks in factorial scheme 2x3+1+3 with four replications, corresponding to two brachiaria sowing depths (2 and 10 cm), three brachiaria species (Brachiaria decumbens, B. brizantha cv. Marandú and B. ruziziensis) and four additional treatments of sorghum and three brachiaria species (monocultures). The grain sorghum used was the DKB 599. The evaluation of the brachiaria forage yield was made up at 98 days after the sorghum harvest. The interrow intercropping of sorghum with Brachiaria ruziziensis, regardless the sowing depth, and with B. brizantha, sowed in 2 cm depth, did not cause reductions in grain yield. The interrow intercropping with brachiaria possible increases in dry matter and crude protein total yields of the forage. The sorghum and brachiaria intercropping in off-season cultivation shows to be a promising cultivation technique to produce grains and forage (dry matter and crude protein) in cerrado conditions. |
