title: Estimation of loss and analysis of nicotine, reducing sugar and chloride in bidi tobacco due to reniform nematode under pot conditions.
abstract: Estimation of avoidable loss in yield of bidi tobacco due to reniform nematode under pot conditions revealed that variety A 119 suffered heavily than ABT 10 due to reniform nematode. Inoculation of reniform nematode @ 2000 J4 per plant significantly reduced the plant growth characters and increased nematode multiplication preferring A 119 variety. Estimation of avoidable loss in cured shoot yield of bidi tobacco due to infection of reniform nematode in individual variety ABT 10 and A 119 has been estimated to the tune of 30.5 and 34.2 per cent with overall loss 31.9 per cent in both the variety 60 DAI. Simply growing of ABT 10 variety irrespective of infection of reniform nematode avoided 29.5 per cent loss in cured shoot yield. ABT 10 recorded significantly high nicotine, reducing sugar and chloride than A 119; inoculation of reniform nematode significantly increased nicotine, reducing sugar and chloride compared to no inoculation. Interaction indicated that inoculation of 2000 J4 of reniform nematode significantly increased nicotine, reducing sugar and chloride in A 119 compared to no inoculation; while significantly reduced reducing sugar and increased chloride in ABT 10. There was no significant impact of infection of reniform nematode on nicotine in ABT 10.
