The aim of the research was to evaluate the effect of foliar application of different doses of Tytanit as a biostimulant on the yield and nutritional value of Medicago × varia T. Martin and Trifolium pratense L. It was assumed that titanium application during any life cycle of alfalfa hybrid and red clover would contribute to their growth, digestibility, and total protein content. In addition, it was expected that increasing doses of Tytanit up to 0.6 dm3 ha−1 would improve the yield and quality of forage plants. Different doses of Tytanit in different ways affected the yield. However, the largest dose of 0.6 dm3 turned out to be the most effective. It contributed to a 38% increase in the yield of hybrid alfalfa and to a 31% increase in the red clover yield. Individual doses of Tytanit in different ways affected accumulation of protein and crude fibre in the dry matter. Used at 0.4 and 0.6 dm3 doses it increased the amounts of protein and crude fibre relative to control. The smallest dose had no significant effect on these parameters. Tytanit did not improve dry matter digestibility, and there was no statistically significant variation as a result of its application. Foliar application of the biostimulant resulted in an increase in the concentration of phosphorus, potassium, and magnesium in plant dry matter. High content of calcium in the plant species before Tytanit application increased further as a response to 0.2 and 0.4 dm3 doses, with a slight increase in the ratio of K: (Ca + Mg) and an excessive growth of the Ca: P ratio, which reduced hybrid alfalfa and red clover nutritional values. Thus, Tytanit doses used in the experiment significantly increased hybrid alfalfa and red clover yields, but the nutritional value of the plants did not improve.

生长调节Tytanit剂量对效果苜蓿X杂物T. Martin和红三叶L.产量和营养价值

该研究的目的是评估叶面施用不同剂量的Tytanit作为生物刺激剂对Medicago  ×  varia T. Martin和Trifolium pratense L的产量和营养价值的影响。假定在任何生命周期中施用钛。苜蓿杂种和红三叶草将有助于它们的生长,消化率和总蛋白质含量。另外,人们期望将Tytanit的剂量增加至0.6 dm 3 ha -1会提高草料植物的产量和质量。不同剂量的泰坦尼以不同的方式影响产量。但是,最大剂量为0.6 dm 3原来是最有效的。它使杂交苜蓿的产量增加了38%,使红三叶草的产量增加了31%。单独剂量的Tytanit以不同方式影响干物质中蛋白质和粗纤维的积累。在0.4和0.6 dm 3下使用剂量增加了相对于对照的蛋白质和粗纤维的量。最小剂量对这些参数无明显影响。泰坦尼(Tytanit)不能改善干物质的消化率,并且应用后没有统计学上的显着变化。叶面施用生物刺激剂导致植物干物质中磷,钾和镁的浓度增加。施用Tytanit之前植物物种中的高钙含量进一步增加,对0.2和0.4 dm 3的响应剂量时,K:(Ca + Mg)的比例略有增加,而Ca:P的比例则过度增加,从而降低了杂交苜蓿和红三叶草的营养价值。因此,实验中使用的Tytanit剂量显着提高了杂交紫花苜蓿和红三叶草的产量,但植物的营养价值并未提高。
