EVALUATION OF GRASS SPECIES FOR ELEMENTS THROUGH ICP-OES TECHNIQUEAbstract
The aim of the study is to screen the grasses of South India for mineral nutrition. The results revealed that the grass species accumulate the major and minor elements at different concentrations. The maximum concentration (ppm) of macroelements in the analysed samples were 12270, 31310, 5309 and 3946 for Ca, K, Mg and P respectively. The maximum concentrations (ppm) of microelements were 50.05, 89.68, 2452, 258.3, 64.01 and 76.05 for B, Cu, Fe, Mn, Mo and Zn respectively. 22% of ash content and 4192 cal/g of calorific value were found. The levels of macro and micro elements determined of the grasses were analysed by using ICP –OES. Elemental studies of the grass species revealed that large amounts of major and minor elements were rich in Aristida hystrix and Echinochloa colonum, which may be suggested for livestock feeding.
