Potentiality of a new mushroom fungus Lentinus connatus Berk. for the production of biomanure from sugarcanetrash (Saccharum officinarum L.) and its impact on the management of groundnut root rot diseases.

摘要

The potentiality of Lentinus connatus, a new mushroom fungus identified in Tamil Nadu, India, for biomanure production from sugarcane trash (Saccharum officinarum L.), was studied in comparison with existing biodegrader Pleurotus sajor-caju. Lentinus connatus elaborated high lignocellulolytic enzymes and biomass production compared to P. sajor-caju. Pit method of composting with periodical turning, using L. connatus with calcium carbonate (activator) drastically reduced carbon:nitrogen (C:N) ratio. High macro- and micronutrients levels were recorded by this treatment. In the greenhouse, soil application of sugarcane trash biomanure at 18 t/ha and reduced level of urea at 13 kg N/ha significantly reduced the groundnut (Arachis hypogaea L.) root rot diseases incited by Thanatephorus cucumeris and Corticium rolfsii, compared to normal recommended doses of inorganic fertilizers.
