Effect of Meloidogyne incognita and Macrophomina phaseolina disease complex on plant growth and fruit yield of Solanum melongena cv. Nageena

Studies were undertaken to determine the effect of sequential, simultaneous and single inoculation of Meloidogyne incognita (2,500 J₂/kg soil) and Macrophomina phaseolina (5.0 g mycelium including sorghum grains/kg soil) on growth and yield of Solanum melongena cv. Nageena. Highest reduction in shoot-root fresh and dry weights, number of fruits and fruit weight was observed in plants inoculated with nematode and fungus simultaneously. Highest reproduction rate (13.4) of M. incognita and root-knot index (3.5) was observed in plants inoculated with the nematode alone, whereas, highest root colonization (19.2) by fungus was observed in plants inoculated with nematode and fungus simultaneously.
