Abstract

The aim of this study was to determine the quality of organically grown red clover herbage and silage after being influenced by supplementary mineral fertilization. The experimental treatments were as follows: control treatment without fertilization (group C), treatment where kalimagnesia (Patentkali) was applied (group P), and treatment where potassium sulfate (SOP) was applied (group S). In each year of the experiment, first-cut herbage was harvested at the beginning of flowering and ensiled. The year of the study had a significant (p ≤ 0.05) influence on the analyzed parameters of herbage and silage, excluding the content of calcium (Ca), acetic acid (AA), and ammonia nitrogen (N-NH3). The organic production system exerted a significant (p ≤ 0.05) effect on the concentrations of crude protein (CP), acid detergent lignin (ADL), water-soluble carbohydrates (WSC), minerals (P, K, Ca, Na), lactic acid (LA), ethanol, and N-NH3. The pattern of fermentation was affected by both experimental factors. True protein (TP) content was determined at 70–84% CP in herbage and 53–65% CP in silages. The energy value and the protein value of herbage varied significantly across years of the study and in response to the combined effects of both experimental factors (p ≤ 0.05). Red clover grown in organic production systems supplied high-quality forage.

不同有机生产系统中红三叶草牧草的质量

本研究旨在确定有机种植的红三叶草草料和青贮饲料受补充矿物质肥料影响后的质量。实验处理如下：不施肥的对照处理（C 组）、施用卡里马格尼西亚（Patentkali）的处理（P 组）和施用硫酸钾（SOP）的处理（S 组）。试验的每一年都在初花期收割头茬牧草并制成饲料。除钙（Ca）、乙酸（AA）和氨氮（N-NH3）含量外，研究年份对草料和青贮饲料的分析参数有显著影响（p ≤ 0.05）。有机生产系统对粗蛋白（CP）、酸性洗涤木质素（ADL）、水溶性碳水化合物（WSC）、矿物质（P、K、Ca、Na）、乳酸（LA）、乙醇和 N-NH3 的浓度有显著影响（p ≤ 0.05）。发酵模式受两个实验因素的影响。真蛋白（TP）含量的测定结果是，草料的 CP 含量为 70-84%，青贮饲料的 CP 含量为 53-65%。草料的能量值和蛋白质值在研究的不同年份和两个实验因素的综合影响下有显著差异（p ≤ 0.05）。在有机生产系统中种植的红三叶草可提供优质饲草。
