Abstract

Macronutrient changes in Ridge gourd varieties inoculated with root-knot nematode, Meloidogyne incognita were investigated. Observations were recorded on macronutrient modifications relating to various parameters like nitrogen, crude protein, phosphorus and potassium content during post infection periods. The variation in nitrogen, crude protein, phosphorus and potassium content in five cultivars i.e. Priya, BSS-1009, Aneeta, Aarti and Harsha were studied 30 days after inoculation. Reduced percentage of nitrogen, crude protein and phosphorus contents were observed in inoculated shoot samples than the healthy counterparts, whereas it increased in root samples. However, an increase in amount of potassium contents was observed in the diseased tissues.
