Abstract:
Research was conducted at the departmental net house to study the micronutrient, iron content variation by interaction effects of antagonistic fungi, Trichoderma viride and root-knot nematode, Meloidogyne incognita in all possible combinations for bio-control of the test nematode infecting ginger germplasm viz. suravi and suprabha. Antagonistic fungi, Trichoderma viride @ 6g pot^-1 alone proved to be more effective among all treatments resulted in higher plant vigour, chlorophyll, and nutrient status (N, P, K, Fe, and Zn). Among all combined treatments, TV→MI (Trichoderma viride inoculated 15 days prior to Meloidogyne incognita) was found to be most efficient, acting as a plant growth stimulator in close association with plant rhizomes and suppressing the root-knot development of M. incognita in ginger plants.
