The yield response of forage maize (Zea mays L.) genotypes to plant density is not as clear as for grain hybrids, where density tolerant and sensitive types have been identified. A study including field trials, laboratory analyses, and in situ digestibility tests with one density-tolerant and one sensitive hybrid was conducted with plant densities of 4 to 16 plants m^–2. The investigations concentrated on stover. There are differences in sensitivity to planting density in forage maize yield. Differences between sensitive and tolerant genotypes in plant density range for maximum yield were 0.43 and 1.18 plants m^–2 for grain and forage, respectively. The decreased sensitivity for grain compared with forage was 50.7 and 100.0% for the sensitive and the tolerant hybrid, respectively. It was not possible to separate the tolerant and sensitive hybrids in terms of total digestible nutrients (TON), a measure of overall feed value. For plant densities lower than those required for maximum dry matter yield, there was a significant difference between the tolerant and the sensitive hybrid in TDN.
