Fertilisation plays a major role in growth and dry matter yield of forage. A field experiment was conducted over two planting seasons on the same site to determine the effect of different fertilisers on growth of corn and soybean and dry matter yield of mixed forage. Six fertiliser treatments with three replications were arranged in randomised complete block design. The treatments were 100% chemical fertilizer (NPK), 100% poultry manure (PM), 50% PM, combined application of 50% PM with biofertiliser, sole biofertilser and untreated (control). The results in the first season showed that 100% NPK produced the highest dry matter yield (13.83 t ha-¹) but in the second season, 100% PM produced a similar dry matter yield (9.91 t ha-¹) with 100% NPK (9.84 t ha-¹). Sole biofertiliser produced the same yield as 50% PM. The results indicate that 100% PM at the rate of 6.3 t ha-¹ significantly increased dry matter yield of mixed forage.
