Abstract

A field trial on estimation of yield losses in jute due to root-knot nematode and wilt bacteria alone and in combination was conducted in naturally infested field. The results revealed that Meloidogyne incognita alone, Ralstoni asolanacearum alone and together caused 18.3%. 26.1% and 35.6% losses in fiber yield of jute, respectively at a pre-plant population densities of 328 J2/250 cc soil for the nematode and 7.2 X 107 cuf/g soil for the bacteria. Similarly, at pre-plant population densities of 264 J2/250 cc soil far nematode and 7.6 X 10s cfu/g soil for bacteria the losses were estimated to be 16.49%, 25.27% and 31.25% due to nematode, bacteria and for the both pathogens respectively.
