An experiment was carried out to study the effect of Meloidogyne incognitaon growth of Pisum sativum (Cv. Kashi Nandini) under glass house conditions by inoculating different inoculums levels i.e. 0 (control), 10, 100, 1000, 10,000 second stage juveniles (J2) of M. incognita along with supernatant. The results revealed that the increase in inoculum level of M. incognita, there was a progressive decrease in growth parameters of the crop as the levels of inocula increased. Significant reduction in plant height, root length and fresh and dry weights of roots and shoots were declined. Maximum galls, egg masses and eggs per egg mass were recorded more pronounced and significant reduction was observed at higher inoculum levels i.e. 1000 and 10,000 J2/pot.

“…The chilli (Capsicum annuum L) is a good source of vitamin C. Capsaicin, an alkaloid element in chilies that has positive health effects, gives chilies their intensely spicy, pungent flavour [1]. Chilies are a wonderful source of vitamins and minerals like magnesium, potassium, manganese, and iron.So, crop productivity is negatively impacted by biotic and abiotic environmental stress.…”

The behaviour of fungal pathogens in a dormant or active state under different changes by infection of the host plant parasitic nematode was related to the function of fungi. Due to RKNs on the chilli in Meloidogyneinfected pot culture, Penicillium sp. demonstrated plant growth-promoting characteristics and nematocidal activities, according to the findings of the current study. This fungus can be used as a growth promoter in Treatments 2 and 3, where a mixture of Meloidogyne sp. and Penicelliumsp. showed higher growth rates and yellowing leaves in some pots, but no knots were found in the roots however, the current research may offer a theoretical basis for a growth promoter agent for better growth in Penicillium inoculated pots and In Nematode inoculated pots, Meloidogynesp can reduce plant growth. In both Meliodogynesp and Penicillium sp inoculated pots, it was demonstrated that decreasing nematode population increased the growth habits of chilies in terms of number of leaves Therefore, it has been demonstrated that Penicellium decreases nematocidal action while promoting growth parameters in chilli plants, and that using preventative measures can somewhat lessen insect infestation in control pots.

“…Generally, the information obtained from the population dynamics of M. incognita and the yield loss during modeling helps design effective nematode management strategies and extrapolate to other nematode species and vegetables. Ahmed et al (2013) demonstrated that the population densities of M. incognita increased from 250-8000 J2 per plant, resulting in an increase in dry weight reduction in chili (C. annuum) from 1.6 -43.9%. Similarly, Di Vito et al (1992) found that resistant cultivars of sweet peppers were reduced by 50% at the Pi of M. incognita ≥ 32 J2 (g soil) -1 .…”

Predicting the damage caused by certain nematode population densities is crucial in deciding whether or not to cultivate pepper and selecting the most suitable management strategies. To understand the relationship between the initial nematode density (Pi) and the final nematode population (Pf), and the damage potential of Meloidogyne incognita to var. Dinsire, a study was conducted under greenhouse conditions. A geometric series of 13 initial densities (0, 0.0625, 0.125, 0.25, 0.5, 1, 2, 4, 8, 16, 32, 64, 128 J2 (g soil) -1 ) of M. incognita was subjected to Dinsire. The treatments were arranged in a randomized complete design with four replications and terminated after 120 days of nematode inoculation. This study showed that the final nematode population, plant growth, and yields decreased as initial nematode inoculums increased. Maximum suppression fresh weight of shoot (43.8%) and fruit (52%) was recorded at Pi ≥ 8 J2 (g soil) -1 . The analysis of Seinhorst's yield loss model indicated the highest tolerance limit (T=0. 64 egg + J2 (g soil) -1 ) recorded for leaf number, while the relative minimum yield (m) of 0.91 and 0. 86 were the highest m values for root length and shoot height, respectively. Furthermore, the maximum multiplication rate (a) and population densities (M) were estimated as 8813.2 and 3420.1 (eggs and J2 (g soil) -1 ), respectively. Therefore, evaluating hot pepper varieties for resistance using a wide range of Pi could generate more reliable information on the host status of pepper varieties.
