302. PHYSIOLOGICAL RESPONSE TO MINERAL NUTRITION ON THE MACRONUTRIЕНТ PROFILE OF EGYPTIAN CLOVER (Trifolium alexandrinum L.) (Физиолошки одговор на минералната исхрана врз макронутритивниот профил на александровата детелина (Trifolium alexandrinum L.)

The aim of this research is to determine the influence of different variants of mineral fertilization (Control, NP, NK, PK, and NPK) on the macronutritional composition of Alexander's clover (Trifolium alexandrinum L.). The experiment was set up in a randomized block design with three replications on alluvial soil. Statistical analysis (ANOVA and Fisher’s LSD test) showed that combined NPK fertilization significantly (p ≤ 0.05 and p ≤ 0.01) increased the contents of proteins, fats, fibers and soluble sugars compared to the control variant. The highest values were observed in the NPK treatment, which indicates a synergistic effect of N, P and K in the biosynthesis of organic matter and improved nutritional quality of the Alexander clover.
