Not AvailableRoot knot nematodes pose serious threat to FCV tobacco production in Karnataka light soil region causing severe loss
in yield and quality. Nematode management by use of carbofuran and dazomet 98% is quite possible, but indiscriminate use of
such chemical nematicides leads to environmental pollution due to residues in water and soil. Hence, poultry manure, which is
a locally available organic source, was evaluated against root-knot nematodes in FCV tobacco nursery for three years. Results
revealed that, there was no adverse effect of poultry manure on tobacco seed germination. At 60 DAS, Poultry manure @ 200 g/m2
was on par with poultry manure @ 250 g/m2
in recording reduced Root-Knot Index (RKI) of 1.36 and 1.34 respectively and also was
on par with neem cake + soil solarization (1.40) and dazomet @ 30 g/m2
(1.22). Similarly application of Poultry manure @ 200 g/
m2
in FCV tobacco nursery beds resulted in 40% reduction in number of root galls /g root, 34% reduction in number of root knot
nematode adult females/g root, 43% reduction in number of root knot nematode egg masses/g root and 36.9% reduction in root knot
nematode soil population/100g soil compared to untreated check. Poultry manure @ 200 g/m2
was on par with poultry manure @
250 g/m2
in recording significantly increased healthy and root-knot free transplantable seedlings to the tune of 48.0 and 59.0 per
cent respectively compared to untreated check.Not Availabl
