Popis:	The economic feasibility of using composted manure from western Kansas feedlots in combination with commercial N in the production of irrigated grain sorghum [Sorghum bicolor (L.) Moench] was evaluated. Effective disposal of large quantities of manure from large scale feedlots has been a concern. Yield data from a west central Kansas experiment station study was used to estimate a quadratic production function where grain sorghum yield is a function of compost and commercial N application rates. Four rates of commercial N (0, 55, 110, and 165 Ib/acre) and five rates of composted feedlot manure (0, 0.9, 1.8, 3.6, and 7.2 tons dry matter per acre) in a factorial arrangement were applied to irrigated grain sorghum [...]
