Seeds of local trees, such Azadirachta indica A. Juss, Adenanthera pavonina L., Leucaena leucocephala (Lam.) de Wit and Eucalyptus spp., were used as aqueous extract at 25, 50 and 100 % concentration to control the activity of Meloidogyne javanica (Treub) Citwood. All seed extracts showed lethal effect on M. javanica eggs, and a gradual decrease in egg hatching and an increase in mortality of second-stage juveniles were observed with the increase in extract concentration. L. leucocephala was found to be most effective in reducing egg hatching, whereas 100 % mortality of juveniles was observed in the case of A. indica seed extract. Number of knots was significantly reduced at 100 % concentration when seeds of chick pea and mung bean were treated and soil was drenched with A. pavonina and Eucalyptus spp. seed extract.

Legumes as an important functional group of land plants are recognized to grow in water-deficient and low-nutrient environment because of their ability to form symbiosis with nitrogen fixing rhizobia and arbuscular mycorrhizal (AM) fungi, which improve nutrient acquisition from the soil and help plants to be well established. Aim of the present study was to evaluate the symbiotic potential of AM fungi, Glomus intraradices alone and/or in combination with two Bradyrhizobium japonicum strains MN-S and TAL-102 in Vigna radiata. Field experiment was conducted to investigate the influence of different microbial symbiotic associations on growth and yield of V. radiata. Dual inoculation of G. intraradices and both bacterial inoculants showed better potential of plant growth promotion over single inoculation of G. intraradices or bacterial inoculants. Both bacterial inoculants in combination with AM proved best with 3.78, 30.17 and 46.80 g plant⁻¹ dry weight at 25, 45 and 90 days after sowing (DAS), respectively. Maximum grain yield of 1,506.87 kg ha⁻¹ as well as phosphorus contents of 1.981 mg g⁻¹ root, 3.830 mg g⁻¹ shoot and 4.935 mg g⁻¹ grain were observed with mix bacterial inoculants and AM at 90 DAS. The interactive effect of bacterial inoculants and AM was synergistically significant which improved the nitrogen contents by 68, 20 and 17% in root, shoot and grain, respectively, compared to uninoculated control at 90 DAS. The present study suggests the suitability of G. intraradices and B. japonicum having synergistic or additive interaction to be used as composite inoculum for enhancing crop production of V. radiata.

Leaves, stem and pneumatophore of Avicennia marina and leaves and stem of Rhizophora mucronata were used as the organic amendments at 0.1, 1 and 5% concentrations in the control of root rot fungi like (Fusarium spp., Rhizoctonia solani and Macrophomina phasoelina) and root knot nematode Meloidogyne javanica on potato. In pot experiments, germination of seeds, shoot length, shoot weight, root length, root weight and number of knots were signifi cantly increased when plant parts like leaves, stem and pneumatophore of A. marina and R. mucronata were used at 1 and 5% concentrations. There was a complete suppression in infection of R. solani and M. phaseolina when A. marina and R. mucronata were used at 5% concentration on potato. Maximum inhibition of knots of M. javanica was observed when powder made from mangrove plant parts was used at 1 and 5% concentrations. Powder from all plant parts, like leaves, stem and pneumatophore, was effective in suppression of root infecting fungi and root knot nematode.

The present investigation was carried out to evaluate the potential of chitosan alone and in combination with various agricultural wastes for the management of rootknot nematode, Meloidogyne incognita on eggplant cv. ‘BR-112’ under greenhouse conditions. The results showed that chitosan as a single or joint treatment with agricultural wastes significantly (p ≤ 0.05) reduced root-knot indices, and the nematode population in soil. As a result, of this, the growth and growth yielding attributes of eggplant were remarkably augmented. Chitosan as an elicitor induced plant mediated systemic resistance against M. incognita in eggplant. The results of the study demonstrated that maximum reduction in eggmass/root, eggs/eggmasses, nematode population and root-knot indices, was acquired by the treatments: chitosan + onion and chitosan + mentha. It was followed by chitosan + Brassica, chitosan + urad and chitosan + coconut whereas, chitosan combined with corn cob waste was found to be the least effective when compared to the control. The application of chitosan alone was effective but not very satisfactory. Compared to the control applications of all the treatments significantly increased plant growth in terms of length, fresh and dry weights, pollen fertility, yield and biochemical parameters such as chlorophyll, carotenoid content and antioxidant enzymes. This may have been due to the eliciting activity of chitosan, causing systemic resistance in the plant and the release of various toxic chemical compounds during decomposition which have lethal effects against the second stage juveniles of M. incognita and nematode multiplication.
