| Summary: | The experiments were conducted to study the effects of N fertilizer and soil moisture levels in winter on stem flowering percentage and yield in Mat Rush (Juncus effusus L.). Irrigation during winter significantly promoted N absorption and accumulation, increased N content in the plant at early growth stage (before 10, April) and final single stem weight. It also markedly reduced stem flowering percentage and number of florets per cyme, resulting in improved quality of rush stem. With an increase in N fertilizer application, N absorption and content in the plants, and stem flowering percentage and number of florets per cyme significantly increased. Mean stem length, effective stem (≥70 cm) and long stem (≥110 cm) percentage, stem number per hill, single stem weight and economical yield were significant higher in N application treatments than in control. However, no difference was found between two N fertilizer levels, 450 kg N/hm<sup>2</sup> and 900 kg N/hm<sup>2</sup>, in effects on above yield and quality parameters. It could be concluded that higher quality and yield may be attained in rush production by means of irrigation during winter and application of a suitable N rate. |
