Sorghum is an excellent alternative to other grains in poor soil where corn does not develop very well,as well as in regions with warm and dry winters. Intercropping sorghum [Sorghum bicolor (L.) Moench]with forage crops, such as palisade grass [Brachiaria brizantha (Hochst. ex A. Rich) Stapf] or guinea grass(Panicum maximum Jacq.), provides large amounts of biomass for use as straw in no-tillage systems or aspasture. However, it is important to determine the appropriate time at which these forage crops have tobe sown into sorghum systems to avoid reductions in both sorghum and forage production and to maxi-mize the revenue of the cropping system. This study, conducted for three growing seasons at Botucatu inthe State of São Paulo in Brazil, evaluated how nutrient concentration, yield components, sorghum grainyield, revenue, and forage crop dry matter production were affected by the timing of forage intercrop-ping. The experimental design was a randomized complete block design. Intercropping systems werenot found to cause reductions in the nutrient concentration in sorghum plants. The number of pani-cles per unit area of sorghum alone (133,600), intercropped sorghum and palisade grass (133,300) andintercropped sorghum and guinea grass (134,300) corresponded to sorghum grain yields of 5439, 5436and 5566 kg ha−1, respectively. However, the number of panicles per unit area of intercropped sorghumand palisade grass (144,700) and intercropped sorghum and guinea grass (145,000) with topdressingof fertilizers for the sorghum resulted in the highest sorghum grain yields (6238 and 6127 kg ha−1forintercropping with palisade grass and guinea grass, respectively). Forage production (8112, 10,972 and13,193 Mg ha−1for the first, second and third cuts, respectively) was highest when sorghum and guineagrass were intercropped. The timing of intercropping is an important factor in sorghum grain yield andforage production. Palisade grass or guinea grass must be intercropped with sorghum with topdressingfertilization to achieve the highest sorghum grain yield, but this significantly reduces the forage produc-tion. Intercropping sorghum with guinea grass sown simultaneously yielded the highest revenue per ha(1074.4), which was 2.4 times greater than the revenue achieved by sowing sorghum only.
