The relatively high yield increase recorded in RHA compared to other treatments might be attributed to high [Mg.sup.2+] produced in plots treated with RHA which Modi and Asanzi (2008) reported to be a major constituent of chlorophyll, proto-chlorophyll, pectin and phytin

phosphorus in wheat bran by sheep.
The enzyme phytase, produced by microorganisms and some plants, must be added to pig diets to utilize phytin
Crude rice bran is rich in B vitamins, oil, high quality protein, phytin
, dietary fiber, silica, oryzanol and other antioxidants, and phytosterols.
Mustard seeds are composed of protein (23-30%), fixed oil (2936%), carbohydrate (12-18%) together with minor constituents including minerals (4%), essential oil (glucosinolates, 0.8-2.3%), phytin
(2-3%) as well as phenolic compounds and dithiolthiones.
Rose AR (1912) The influence of phytin
The presence of anti-nutrients such as phytin
, tannin, oxalate, alkaloids and flavonoids may have also contributed in part to the growth reduction among the experimental pigs.
Free soluble phosphate reserves plays vital role in energy transfer, metabolic regulation, and important structural constituent of biomolecules like phytin
bodies in the ungerminated seeds, protein and nucleotide phosphorylation [25,27].
Native soil phosphorus is organically bound and available in the form of phytin
, or its derivatives, has low solubility and mobility, and thus is not accessible to plants.
