• Identified some wild relatives of pigeonpea resistant to Heterodera cajani and Meloidogyne javanica. Identified some lines of mungbean, urdbean, lentil and fieldpea resistance to root knot nematodes.
• Demonstrated the susceptibility of some wilt resistant pigeonpea and chickpea genotypes/donors in presence of root knot nematodes.
• Worked out the integrated nematode management in pigeonpea, urdbean and chickpea. Identified two cropping sequences Sorghum + Urdbean – Wheat and Urdbean – Wheat + mustard which can reduce 82.7 and 75.6% root knot nematode population in one year.
• Found out the toxic effects of root exudates of sorghum on root knot nematode juveniles.
• The status of nematode problems in chickpea, pigeonpea, lentil, mungbean and urdbean was found out by surveying the area for three years. Lesion nematode, Pratylenchus thornei was found major nematode infesting chickpea and lentil, Hoplolaimus was most prominent nematode in pigeonpea in Bundelkhand.
• Heterodera cajani infection in urdbean caused reduction in grain yield as well as total protein content of grains.
• In absence of host Heterodera cajani survived more than three years but less than four years in cysts.
• Worked out 2 years non host cropping sequence to bring down Heterodera cajani population.

To work out cropping systems for the management of root knot and pigeonpea cyst nematode in pulse crops. Also working on bio fumigant crops for management of root knot nematodes in pulse based cropping systems.
