BMR Biotechnology-Qualitative and Quantitative Screening of Grasses for Macro and Micro Nutrients

The present study is aimed to screen the selected grasses of South India for qualitative and quantitative mineral content. The results revealed that the grass species accumulate the major and minor elements at various concentrations. The concentration of macroelements were found to be 9503, 51360, 4650 and 3473 (ppm) of Ca, K, Mg and P respectively and microelements were 40, 219, 2698, 261, 68 and 108 for B, Cu, Fe, Mn, Mo and Zn (ppm) respectively. 17% of ash content and 3826 cal/g of calorific value were found as the selected species. The levels of macro and micro elements of the grasses were determined by using ICP –OES. Elemental analysis studies of the grass species revealed that large amounts of major and minor elements were found rich in Fimbristylis cymosa and Scleria lithosperma, which may be suggested for livestock feeding.
