Abstract: Plant tissue analysis is the direct measurement of various types of nutrients present in plant at the time of sampling. It helps to diagnose the deficiency and toxicity of particular mineral element at particular growth stage of plants before the appearance of visual symptoms. This paper intended to review the various types of qualitative and quantitative techniques used to determine the concentration of mineral nutrients present in plant tissue. The quantitative concentration of mineral elements present in horticultural crops can be determined by atomic absorption spectrometry (AAS), inductively coupled plasma atomic emission spectrometry (ICP-AES), inductively coupled plasma mass spectrometry (ICP-MS), flame atomic absorption spectrometry (FAAS), graphite-furnace atomic absorption spectrometry (GF-AAS), spectrophotometry, ion-selective electrode method, X-ray fluorescence spectrometry, electromigration techniques, nuclear magnetic resonance technology and some electrochemical techniques. Review shows that atomic absorption spectrometry (AAS) is widely used destructive technique for the determination of several mineral elements such as nitrogen (N), phosphorous (P), potassium (K), calcium (Ca), sodium (Na), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), zinc (Zn) and boron (B). Other non destructive techniques such as DRIS and colorimetric method are also employed to determine the mineral nutrient concentration in plant tissue.
