Description The present investigation had been done to study the effect of micronutrients (Zn, Cu and Mn)
on biochemical constituents in clusterbean (Cyamopsis tetragonoloba L.) seedlings infected with
Rhizoctonia species. The seedlings were grown under eleven different micronutrient treatments, in earthen
pots, filled with inoculated soil. The inoculated soil was prepared by the pretreatment of soil with 250mg
(wet weight) of Rhizoctonia inoculum. Similar set was maintained in uninoculated soil. Morphological
parameters like fresh and dry weight of shoot and root, shoot and root length decreased with infection but
increased with micronutrient treatments. Chlorophyll, non-structural carbohydrate and IVDMD content
decreased in inoculated seedlings as compared to uninoculated one. Oxidative enzymatic activities (PPO,
POX, PAL and TAL), crude protein content, phenolic content and structural carbohydrates (ADF,
Cellulose, Lignin and Silica) increased in inoculated seedlings and this increase was further heightened by
micronutrient treatments, to counteract the fungal invasion. On the basis of present study, it was
concluded that Zn2+ 20ppm
