Most of the cultivated crop plants absorb comparatively low amounts of selenium but have differential accumulation and susceptibility to selenium. Crops like raya berseem, sorghum, cowpea, pea and wheat and their varieties show differential susceptibility to native and added selenium. The varieties of crops also behave differently to native and added dose of selenium, and some varieties absorb higher amounts without affecting growth and yield. The disease syndrome ‘Degnala’ in Haryana and Punjab appears in animals fed on high selenium fodders and may be due to direct or indirect effects of selenium toxicity through decreased concentration of S, N, S-amino-acids and then proteins which may also differ from crop to crop depending on selenium concentration and different metabolic production in plants.
