Effect of integrated nutrient management practices on soil microbes in turmeric

R. Kuttimani, E. Somasundaram

Efficient and rational use of manures and fertilizers is imperative not only for obtaining more yields unit area-1 on a sustainable basis, but also to ensure safe food and to conserve the environment. Keeping these aspects in view, the present research work was undertaken to evaluate the organic sources of nutrients on growth and yield of turmeric. Field investigations were carried out at Agricultural Research Station, Bhavanisagar of Tamil Nadu Agricultural University, Coimbatore. The experiment was laid out in Randomized Block Design replicated thrice. It consisted of fifteen treatments comprising twelve treatments of commercial organic sources of nutrients, two treatments of farm yard manure and one treatment with 100 per cent Recommended Dose of Fertilizers (control). Chemical source of nutrients like N and K were applied in five split doses along with wellgro formulations, while the full dose of P was applied as basal. During both the seasons microbial population was influenced by integrated nutrient management practices and noticed significant difference among the treatments. Among the treatments, the highest microbial population was recorded with 100% RDF along with 40% wellgro soil (T3). During 2010-2011, T3 recorded the maximum bacterial and fungal population respectively at 90 (83.3, 67.0), 135 (124.7, 94.3), 180 (169.0, 114.7) and 245 (126.7, 84.0) days after planting. Similar trend was observed during 2011-2012 also. The minimal microbial count was observed under control (100% RDF alone). Hence it is concluded that turmeric responded favourably to wellgro formulations along with chemical fertilizers. Among the different treatments, application of 100% RDF + 40% wellgro soil would be the better practice to enhance the microbial load inturn improves the yield.
