“…In the same vein, application of NPK at 200, 400 and 600 kg ha -1 600 also had a significant lower population densities of M. incognita, H. multicinctus, P. coffeae and R. similis. Our findings were consistent with earlier studies that the use of appropriate levels of NPK fertilizers have good effects on plant growth factors with resultant reductions in plant-parasitic nematode populations (Irshad et al, 2006;Ameen et al, 2013;Osman et al, 2015;Kolawole et al, 2018). Contrarily, nematode populations were reported to have increased due to NPK and manure combined with chemical fertilizer (Hu et al, 2018).…”

Low soil fertility, pests and diseases are major problems of growth and establishment of cacao seedlings on the field. Cocoa production increases by new plantings and rehabilitation of moribund farms, but a build-up of plant-parasitic nematodes (PPN) causing dieback and declining soil fertility has discouraged many farmers, leading to a reduction in crop productivity. In this study, the potentials of some organic wastes as fertilizers and their effects on establishment of cacao seedlings in PPN infected soils was investigated at Ibadan and Owena of Southwestern Nigeria. Goat dung (GD), organic fertilizer (OF), organo-mineral fertilizers (OMF) and NPK 15:15:15 were applied at 200, 400 and 600 kg ha-1, respectively, to cacao seedlings one month after transplanting, while unfertilized served as control. Results from the experiments showed a significant increase in percentage survival of cacao seedlings under organic fertilizers at Ibadan and Owena compared to NPK and control even at the lowest rate of 200 kg ha-1 3 years after transplanting. The incorporation of GD, OF and OMF significantly reduced the population densities of PPN compared to control. Therefore, GD, OF and OMF at 200 kg ha-1 are recommended for soil application to enhance the field establishment of cacao seedlings in the soil infected with PPN.

“…This disagrees with the findings of Okae-Anti et al [18] where the resulting increase in nematode population caused a decrease in the yield of plantain. On the contrary, Kolawole et al [25] reported that NPK fertilizer significantly reduced root-knot nematode populations in the roots, soil, and on the tuber of yam, however, the nematodes increase did not reduce yam tuber weight, but reduced its quality. Table 3 recorded that season of planting was highly significant on grain yield and population of Pratylenchus brachyurus.…”

Field studies were conducted in the early and late season of 2010 in the tropical rainforest zone of Nigeria to investigate the effects of NPK fertilizer as an inorganic soil amendment at 75 kg/ha and 150 kg/ha in four replications on population densities of Pratylenchus brachyurus and on crop yield of maize. Seeds of maize variety, DMR LSR-Y were collected from Institute of Agricultural Research and Training, Ibadan. The experimental field was naturally infested with Pratylenchus spp. due to subsequent continuous cultivation of susceptible crop on the field. Seeds were planted and NPK was applied around the roots of maize plants 3 weeks after seedling emergence. Soil samples were taken on treatment plots at planting and harvest to determine the percentage change in nematode population. At the end of experiment, NPK application resulted in the increase in the nematode population. However, the grain yield of maize was not reduced by the increased nematode densities. The results of this study suggests that the usage of NPK caused a surge in the nematode reproduction on the field due to the availability of more feeding sites on the actively growing root system of the crop.

“…It is important to highlight that plants associated with AMF are more robust, as these fungi enhance nutrient and water absorption, making these plants better nourished and vigorous and thus better equipped to withstand the presence of the pathogen (Kolawole et al 2018;Campos 2020). Table 10.1 summarizes the effects on AMF, Meloidogyne, and plant parameters in experiments with AMF and Meloidogyne.…”
