Crude fiber, ash and crude fat in various parts of root had highly significant correlation each other. In shoot, crude fiber showed highly significant negative correlation with crude fat or crude protein which were in highly significant positive correlation each other. In whole plant, crude fiber and ash, crude fat and crude protein, Mn and Cu, ash and Ca, and ash and B showed positive correlation respectively and negative between crude protein and crude fiber.
Ash, crude fat and curde fiber showed highly significant positive correlation with all mineral nutrients in root while in shoot pairs having significant correlation were less and most of these were in negative correlation. Ash with Mg, K or Cu, crude fat with B, crude fiber with Cu, K, Mg in root and crude fat with Mn in shoot were specially high significant pairs. Ash with B and crude fat with Mn were significant in root, shoot and whole plant.
Saponin contents in root showed highly significant positive correlation with crude fiber, crude fat, ash and with all other mineral nutrients except N, P, Mg while, in shoot, it showed, negative correlation with K and crude fiber, and positive with N, Mn, Cu, and crude fat. Saponin showed positive correlation with crude fat, Mn, Cu, in root, shoot and whole plant.
