“…There was a progressive increase in the number of galls and egg masses with an increase in inoculum level from 100 to 5000 J 2 in the plants harvested at 15, 30, and 45 days after inoculation and at 5000 J 2 per plant at 60 and 90 days after inoculation, the number of galls, egg masses, and female nematodes were decreased. Similar ndings were obtained by Paruthi and Gupta (1985) for bottle gourd after 45 days of inoculation, by Ravishankar and Singh (2008) There was a progressive increase in the nematode population in the soil with increasing in inoculum level from 100 to 5000 J 2 per pot 15, 30, 45, and 60 days after inoculation but 90 days after inoculation there was slight decrease in the nal nematode population at inoculum levels of 2000 and 5000 J 2 per pot. A gradual increase in the nematode population with increasing inoculum level was reported by Venkatesan (2009) 2022) for common bean.…”

This study investigated the impact of varying initial population densities of the root-knot nematode Meloidogyne incognita on the growth of muskmelon (Cucumis melo L.). Muskmelon, an important fruit crop with increasing global recognition, faces the threat of Meloidogyne spp., particularly Meloidogyne incognita, which significantly affects plant growth and yield. The experiment, conducted in a controlled glasshouse environment, involved inoculating muskmelon plants with different population densities of M. incognita ranging from 100 to 5000 J2 (infective second-stage juveniles). The study assessed growth and nematode reproduction parameters, at 15, 30, 45, 60, and 90 days after inoculation. The results revealed that M. incognita became pathogenic to muskmelon at inoculum levels of 500 J2 and above per plant. The crop exhibited significant reductions in shoot and root lengths, as well as fresh and dry weights. The study also documented changes in the nematode population in the soil, reproductive rates, and other growth parameters. These findings offer crucial insights into the relationship between nematode density and muskmelon growth, contributing to a better understanding of the dynamics of M. incognita infestation. These findings can aid in developing targeted strategies for managing nematode-induced losses in muskmelon cultivation.
