Abstract:
The present study was carried out in nematode infested soil at the experimentation field of the Court yard of Department of Plant Pathology, SHUATS in a randomized block design (RBD) during Kharif season 2021 to evaluate the different organic composts, T₁-spent mushroom compost + FYM, T₂- Vermicompost + FYM, T₃-Neem cake + FYM, T₄-Spent mushroom compost + Vermicompost + FYM, T₅- Vermicompost + Neem cake + FYM, T₆ - Spent mushroom compost + Vermicompost + Neem cake + FYM was used as basal application along with untreated control. The result revealed that T₆ - Vermicompost + spent mushroom compost + Neem cake + FYM plant height (cm), Root length (cm), Root weight (gm), Root knots are significantly superior. plant height (cm), at 30,60, and 90 DAS (52.13,79.66 and 95.3 cm) comparison to other treatments and the minimum Root weight (gm) was recorded at 60,75 and 90 DAS in T₆ – Vermicompost + spent mushroom compost + Neem cake + FYM (5.7,8.17 and 11.35 gm) as compared to other treatments. The maximum Root length (cm) was recorded at 60,75 and 90 DAS in T₆ Vermicompost + spent mushroom compost + Neem cake + FYM (18.70,20.15 and 20.36 cm) as compared to other treatments and The minimum nematode intensity was recorded at 60,75 and 90 DAS in T₆ – Vermicompost+ spent mushroom compost + Neem cake + FYM (4,16 and 56) as compared to other treatments. Thus, the use of organic compost can be exploited for the management of root knot nematode (Meloidogyne incognita) of okra.
