Samples of plants of red clover cv. Dajana were collected from a strict field experiment carried out in 2005-2006. Two factors were considered: 1. Seeds originating from plantation of red clover, foliar fed with boron and molybdenum at the following rates: 0; B – 0.3; Mo – 0.01; B – 0.3 + Mo – 0.01; B – 0.45; Mo – 0.015; B – 0.45 + Mo – 0.015 kg ha^-1; 2. Two cuts of red clover. A consequential impact of feeding the seed red clover with boron and molybdenum was observed; it considerably diversified the contents of N, P, K, Ca, Mg, specific protein, crude fibre, NDF, ADF, and microelements (B, Cu, Mn, Mo) in the plants. Better effects were most often recorded for seeds fed at the following rates: B – 0.45; Mo – 0.015, and B – 0.45 + Mo – 0.015 kg ha^-1. Great variability of above components and zinc in the plants resulted from the weather during particular seasons. From the point of view of red clover as a fodder, better results were noted for plants from 2006 and from the 2^nd cut.
