Figures & data

Table 1. Fungal treatments supplemented with different soil amendments

S N.	Soil amendments	Application rate	Time of application
1	Superphosphate	28 g/kg	applied (3 week) before transplanting at the depth of 10–12 cm
2	Organic Manure (Khadi commission)	44.4 g/kg	applied (3 week) before transplanting and thoroughly mixed, soil was watered
3	Green manure (residue of Medicago sativa and Sesbania aegyptiaca)	88.8 g/kg	applied (3 week) before transplanting

Figure 2. Effect of different soil amendments and treatments alone or in combinations on the percentage of mycorrhizal colonization (a), amount of CFU per gram X 10³ (b) of C. annuum plants infected with M. incognita. Within columns values of each parameter with the same superscript are not significantly different at (P = 0.05) Duncan’s multiple range test (DMRT). Soil amendments, Cs – Control Set, Sp – Superphosphate, GM – Green Manure, OM – Organic Manure, and Soil treatments, C – Control, M – R. fasciculatum, NM – M. incognita with R. fasciculatum, NMF – M. incognita with R. fasciculatum and P. lilacinus.

Figure 3. Effect of different treatments and soil amendments alone or in combination on the shoot length (a), root length (b), shoot fresh weight (c), root fresh weight (d), shoot dry weight (e) and root dry weight (f) of C. annuum plants infected with M. incognita. Within columns values of each parameter with the same superscript are not significantly different at (P = 0.05) Duncan’s multiple range test (DMRT). Soil amendments, Cs – Control Set, Sp – Superphosphate, GM – Green Manure, OM – Organic Manure, and Soil treatments, C – Control, N – M. incognita, NF – M. incognita with P. lilacinus, NM – M. incognita with P. lilacinus, NMF – M. incognita with R. fasciculatum and P. lilacinus.

Figure 4. Effect of different treatments and soil amendments alone or in combination on number of galls per root system (a), number of egg masses per root system (b), percent egg parasitization (c) and fruit yield (d) of C. annuum plants infected with M. incognita. Within columns values of each parameter with the same superscript are not significantly different at (P = 0.05) Duncan’s multiple range test (DMRT). Soil amendments, Cs – Control Set, Sp – Superphosphate, GM – Green Manure, OM – Organic Manure, and soil treatments, C – Control, N – M. incognita, NF – M. incognita with P. lilacinus, NM – M. incognita with P. lilacinus, NMF – M. incognita with R. fasciculatum and P. lilacinus.
