IMPACT OF ORGANIC AND INORGANIC MANAGEMENT AND PLANT-BASED PRODUCTS ON PLANT-PARASITIC AND MICROBIVOROUS NEMATODE COMMUNITIES

Abstract

Application of poultry and cattle manures, inorganic fertilizer in the form of urea and neem-based urea-coating agent 'Nimin' and biopesticide 'Suneem G' significantly reduced populations of Meloidogyne incognita and other plant-parasitic nematodes and their symptoms on the plant and increased the populations of microbivorous nematodes. Enhanced growth of tomato in treated soil was directly correlated with the suppression of plant-parasitic nematode populations. Higher dosages resulted in greater effects.
