Abstract:
Tobacco is a one of the commercial products prepared from the tobacco leaves by curing them. Among the different species of tobacco, Nicotiana tabacum and Nicotiana rustica are well known tobacco species grown commercially across the world. Tobacco contains several phyto-chemicals like nicotine a principle alkaloid known for its insecticidal property in the form of nicotine. Recent studies have revealed that the AM fungal colonization is likely to induce growth promotional activities like number of leaves per plant and yield of tobacco per plot compared to uninoculated control under Orobanche infested soils. In this regard a field investigation was carried out to evaluate the three different methods of application of AM Fungal culture viz., planting of pre colonized tobacco seedling; soil application and the combination of both. The experiment was carried out in Orobanche infested soils of tobacco growing areas of Nipani in Belagavi district. The results of the present field investigation has revealed that the yield of tobacco at 150 DAP increased in the treatment received both planting of pre colonized tobacco seedling as well as soil application of STD AMF (2.52 kg/plot) which is significantly higher to the treatment received pre colonized tobacco seedling with UASDAMFT alone (2.44 kg /plot). However the lowest yield performance was recorded in uninoculated control tobacco plants (1.73kg/plot). Furthermore number of tobacco leaves per plant at 120 DAP increased in the treatment received pre colonized plus soil application of STD AMF at the time of planting documented the highest tobacco leaves (25.44 leaves/plant) compared to un inoculated control(17.55 leaves/plant). Thus our findings are of positive indicative of the effectiveness of application of AMF as mycorrhized seedlings followed by soil application will be a promising strategy to develop a growth promotional activity in tobacco under Orobanche infested soils.
