dc.description.abstractABSTRACT The research investigation entitled “Modulation of eco-friendly management practices against Meloidogyne incognita (Kofoid and White) Chitwood in tomato (Solanum lycopersicum L.)” was conducted to ascertain the status of M. incognita as pest ofChitwood in tomato of state of Himachal Pradesh and to explore the best possible management schedules in susceptible cultivars of tomato. The nematode at threshold level of inoculum inflicted avoidable quantitative losses to the tune of 35.2 to 37.4 per cent during two years under experimentation. The test nematode was found to be highly pathogenic to tomato even at the low levels of inoculum. Management of M. incognita at nursery level was found to be of utmost significance. Among the various nursery treatments viz., dazomet, metham sodium, jeevamrit, Trichoderma viride and Pseudomonas fluorescence against the nematode, the highest germination rate was recorded in former three treatments; jeevamrit producing the most vigorous and healthy looking seedlings. However, number of galls was appreciably high on seedling roots raised in jeevamrit treated soil as compared to those receiving nematicidal treatment. Thirteen treatment combinations modulated to manage M. incognita revealed the necessity of nematode control in nursery, as the seedlings raised in treated nurseries performed significantly better in the field than the seedlings grown in untreated nurseries, despite receiving similar treatment combinations in the field. Though, significantly improved quantum of fruit production over control was achieved in all the management schedules, four modules producing the highest yields were rated as the best. Of these, two modules involving nursery treatment with dazomet, seedling root dip in neem formulation /carbosulfan, followed by field application neem cake enriched with T. viride, though, produced highest quantity of fruits, had lower benefit cost ratio as the components used in the referred schedules were highly expensive. Other two modules involved application of beejamrit, jeevamrit and dasagavya. On the basis of benefit cost ratio, the two modules involving seed application of beejamrit followed by jeevamrit drenching in field and dasagavya application in nursery as well as in field, were found the most economical; the latter producing higher fruit yields than the former.en_US
