The present investigation was undertaken with objectives of studying the agronomic practices such as sowing time and an additional nitrogen (N) application after fodder cutting on growth attributes, lodging, nitrogen use efficiency, yield attributes and fodder and grain yields in dual-purpose barley. Three sowing dates and five cutting management practices were evaluated in split-plot design. The results revealed that sowing on 15 October resulted in higher leaf area index (LAI) and chlorophyll content index (CCI), whereas un-cut crop produced higher LAI. An additional nitrogen application after each cut, i.e., 50 and 60 DAS resulted in higher CCI values. Lodging incidence reduced with delayed the sowing. Grain, straw and fodder yields of barley decreased with delayed sowing. October 15 sown crop and cut at 60 DAS + N₁₅ resulted in higher agronomic efficiency, apparent nitrogen recovery and partial factor productivity. Crop sown on October 15 resulted in 10.6 and 32.4% more grain yield and 15.5 and 20.1% more fodder yield than that sown on October 30 and November 15, respectively. Control and cutting for fodder at 50 DAS produced similar grain yields, but were significantly higher than the other cutting management treatments. Cutting at 60 DAS gave higher fodder yield, but at the cost of 20.6–22.7% reduction in grain yield of barley. Early sowing on 15 October with fodder cutting to 50 DAS or cut to 60 DAS with an additional N application deserves a special attention for increasing productivity and N use efficiency in dual-purpose barley.

本研究的目的是研究农艺实践，例如播种时间和饲料切割后额外施氮 (N) 对两用大麦的生长属性、倒伏、氮利用效率、产量属性以及饲料和谷物产量的影响。在裂区设计中评估了三个播种日期和五个扦插管理实践。结果表明，10 月 15 日播种的叶面积指数 (LAI) 和叶绿素含量指数 (CCI) 较高，而未切割作物的 LAI 较高。每次切割后额外施氮，即 50 和 60 DAS 导致更高的 CCI 值。倒伏发生率随播种延迟而降低。大麦的粮食、秸秆和饲料产量随着播种延迟而下降。10 月 15 日播种作物并在 60 DAS + N _15时减产导致更高的农艺效率、表观氮回收率和部分要素生产力。与 10 月 30 日和 11 月 15 日播种的作物相比，10 月 15 日播种的粮食产量分别增加了 10.6% 和 32.4%，饲料产量分别增加了 15.5% 和 20.1%。50 DAS 的饲料控制和扦插产生了相似的谷物产量，但明显高于其他扦插管理处理。以 60 DAS 切割可提高饲料产量，但代价是大麦谷物产量减少 20.6-22.7%。10 月 15 日提早播种，将饲料减至 50 DAS 或减至 60 DAS 并额外施氮，以提高两用大麦的生产力和氮利用效率，值得特别注意。
