Abstract:
The present investigation entitled “Effect of biocontrol agents on growth and rhizome rot of turmeric” was undertaken to examine the performance of biocontrol agents on rot control in turmeric, and yield components in Turmeric. The experiment was carried out during kharif from 2017-18 and 2018-19 at Turmeric research station, Kammarapally, Nizamabad District, Telangana. Among the interaction effects between different types of varieties and different biofertilizers, Selam along with the application of Trichoderma viridae recorded significantly the highest values in different parameters at almost all growth stages. Growth characters like the plant height (158.67 cm), number of tillers (4.67), number of leaves (15.83), leaf area (1002.97 cm²), leaf area index (334.32 cm²), biomass of the plant (992.89 g m^-2), number of mother rhizomes (3.00), number of primary rhizomes (10.34), number of secondary rhizomes (17.83).
