Abstract

Pot culture experiment designed to study the effect of bio-fertilizers, viz. azolla and azospirillum on root-knot nematode, Meloidogyne incognita has revealed that okra plants treated with dry azolla (3%) exhibited enhanced growth of shoot length, fresh and dry weight of shoot and root and pod yield. Maximum reduction in number of adult females, egg masses, eggs per egg mass and soil nematode population was recorded in the plants treated with dry azolla (3%). In general all the treatments having bio-fertilizers differed significantly compared to untreated control in reducing root-knot nematode, and increasing plant growth of okra.
