Abstract

A glasshouse and field experimental was conducted by using Trichoderma harzianum (Th 43), Pseudomonas fluorescens (Pf 173) and Jas Mycorrhizal (AMF) for plant growth promotion and management of root rot and wilt disease of tomato. There were eight treatment combinations for glass house as well as field experiment. In glasshouse maximum germination (91%),shoot and root length (40.83 cm, 9.79 cm), fresh & dry shoot weight (152.00 g, 28.38 g), fresh & dry root weight (9.33 g, 3.90 g), plant vigour index (4301.45) was recorded in treatment combination of Th + Pf + AMF. In experimental field maximum reduction of disease over control (72.16%) was found in treatment combination of Trichoderma harzianum (Th 43) + Pseudomonas fluorescens (Pf 173) + Jas Mycorrhiza (AMF). The maximum yield of tomato (486.70 q/ha) was also recorded in same treatment combination.
