The present study investigated the responses of hybrid maize, Bisi-321, -286 and -234, to different fertiliser dosages in fodder production and quality at different harvest timings and grain yield. Plant density was set at 1 plant/hill. The experiment was established in a 972 m2 cut-fill landscape with a raised bed, which was distributed on 27 plots. A 10 t/ha of animal manure was applied. Three different fertiliser treatments, 100 % fertiliser dosage (control), 50 % fertiliser dosage + foliar fertiliser and 100 % fertiliser dosage + foliar fertiliser, were used. The maximum fodder biomass of 720.6 g/plant was obtained at 95 days after planting (DAP), with only a slight difference compared to 85 DAP (714.9 g/plant). The corn ear biomass increased around threefold from 75 (117.7 g/plant) to 85 (303.9 g/plant) DAPs, marking the onset of the rapid grain-filling phase in developing kernels. The contents of ash, crude fibre and protein in fodder peaked at 75 DAP and declined significantly through 95 DAP. However, starch and crude fat were not significant. Based on the quantities of ash, crude fat, protein and starch, the optimal harvest timing for fodder production was 95 DAP. Bisi-321 produced the highest fodder biomass (31.59 t/ha) under control, while Bisi-286 maintained a strong response (28.47 t/ha) even with a 50 % reduction in fertiliser dosage. Despite a lower yield in fodder biomass than other hybrids, Bisi-234 produced a strong grain yield (3 t/ha) even under control. In conclusion, the optimal harvest timing for fodder is 95 DAP. Bisi-324 is well-suited for green fodder production, whereas Bisi-234 is for grain production.
