Popis:	Forage production is influenced by such factors as applied nutrients, water availability, and harvest interval (for perennials). Logistic models have been developed for response to single and multiple elements such as nitrogen (N), phosphorus (P), and potassium (K). This analysis focuses on response of corn (Zea mays L.) for silage to applied N, P, and K. The three elements were applied in fixed proportion in the field study, which presents particular challenge for parameter estimation. The multiple logistic model is shown to describe the data rather well. A step‐wise procedure is outlined for parameter evaluation. Dry matter yield showed greatest response to applied N, but plant K concentration was quite sensitive to applied K.
