Abstract

Banana is an important cash crop cultivated in several states of India, including Tamil Nadu. Wilt disease caused by the fungal pathogen is a severe disease of banana resulting in great economic loss to the farmers. Although the pathogen occurs in the soil and in suckers, the visible symptoms may be seen only after several months. In the meantime, for the development of disease, the physico-chemical factors of the soil along with the atmospheric factors play an important role. So it is an important step to maintain the unfavourable soil condition for the pathogen by analysing the soil samples. In the present study, spectroscopical analysis has been done in order to know the difference between the soil of healthy and diseased plants of five susceptible varieties and five resistant varieties of banana from various localities of Tirunelveli district, Tamil Nadu. The results of macronutrients (NPK) obtained by classical quantitative methods, have been confirmed by IR spectroscopic analysis.  Thus the IR spectroscopic analysis of soil samples clearly shows the difference in absorption spectrum between soil samples of susceptible (diseased and healthy) and resistant varieties of banana. Such spectroscopic difference is mainly due to the difference in concentration of macronutrients (NPK). Thus it is concluded that, when compared to tedious-classical methods of soil analysis, the simple and quick spectroscopic analysis of the soil will be more useful to identify the soil which is more conducive for the development of wilt disease in Banana.
