ABSTRACT
Pigeonpea (Cajanus cajan L.) is one of the most extensively grown legume crops in India. Wilt in pigeonpea caused by Fusarium udum is one of the serious and economically important disease and widely prevalent throughout the country. Under in vitro conditions six nutrients viz., zinc sulphate, boron, ammonium sulphate, ferrous sulphate, calcium sulphate and magnesium sulphate were screened. Among them the two effective nutrients (zinc sulphate and boron) were culled out and the compatibility of Trichoderma viride was checked and developed commercial formulation of Trichoderma viride enriched Zinc sulphate and boron which inhibits the mycelial growth and dry weight of Fusarium udum. Under glass house conditions the soil application of zinc sulphate and boron enriched T. viride (10g / 5kg of pot soil) talc formulation reduced the wilt incidence and increased the zinc, boron uptake and ultimately reflected in an increased yield.
Key words :
Fusarium udum, Nutrient enriched, Nutrient uptake, Pigeonpea, Soil application, Trichoderma viride.
