摘要

堪萨斯州东南部的生产者广泛使用原生草甸。然而,在堪萨斯州东南部,关于提高农艺性能的管理实践的研究很少。本研究评价了石灰、氮、磷、钾复合施用对原生草甸产量和牧草品质的影响。在研究的第一年,石灰施用和磷钾施用对原生草地的产量和饲料质量没有影响。然而,与春烧相关的施氮量增加了产量、粗蛋白质和总可消化养分。

Yield and Forage Quality on Native Meadows as Affected by Burn and Fertilization Management
Summary Native meadows are widely used by producers in southeast Kansas. However, there are few studies about management practices to improve agronomic performance in southeast Kansas. This study evaluated the spring burn effect combined with the application of lime, nitrogen, phosphorus, and potassium on yield and forage quality in native meadows. Yield and forage quality on native meadows were not affected by lime application, or P and K fertilization in the first year of the study. However, N fertilization increased yield, crude protein, and total digestible nutrients when associated with spring burn.
