ABSTRACT
An investigation was undertaken to develop an optimum nutrient schedule for double sucker planted banana. The experiment consisted of three levels of nutrients (Recommended dose of nutrients or RDN, 133% of RDN and 167% of RDN) and three sources of organic manure (Farm yard manure@15kg pit-1, Vermicompost @ 5kg pit-1 and fresh banana residue@ 20kg pit-1) laid out in factorial RBD with three replications. The pseudostem height and girth did not differ significantly with nutrient levels and organic sources. However, the number of functional leaves, total functional leaf area and LAI recorded maximum values with FYM and 133% RDN. Shelf life did not vary with any of the treatments. Among the treatment combinations FYM and 133% of RDN proved superior to other treatments in total income, net income and BCR (4.64) due to higher yield (38.21 t ha-1). From the results it could be concluded that the double sucker planted banana could be manured with 133% of RDN (400:153:600 g NPK pit-1) if the organic source is FYM or fresh banana pseudostem and if vermicompost is used as the organic source RDN (300:119:450 g NPK pit-1) is sufficient for higher yield and net returns. All the major soil nutrients showed a build up after the experiment indicating its sustainability.
