The growth and yield responses of a local banana variety, Velchi (Ney poovan type-AB), and a commercial banana variety, Grand Naine (Dwarf cavendish type -AAA) were evaluated in five nutrient management regimes, viz., T1: recommended dose of fertilizers (RDF), T2: RDF + integrated specific nutrient (ISN) mix; custom made with organic, inorganic and biological components, T3: RDF + integrated general nutrient (IGN) mix available in market, T4: organic nutrient management (ONM) and an absolute control (AC) without any nutrients. Results revealed that RDF along with IGN mix and ISN mix accelerated the vegetative growth in terms of plant height (203.87 and 202.20 cm, respectively) and stem girth (53.77 and 52.50 cm, respectively). The highest number (13.07) and width (65.73 cm) of leaves were recorded in RDF + ISN treatment. Banana plants treated with RDF + ISN mix yielded an average bunch weight (19.28 kg), twice that of absolute control. Other yieldcontributing parameters such as fruit weight (79.75 g), fruit length (15.71 cm), and fruit circumference (11.20 cm) were also high in the same treatment. A single application of 1 kgplant-1 ISN mix along with RDF in 3rd month after planting produced 1.5 times heavier bunches than the plants treated with RDF alone. Both Grand Naine and Velchi banana production with ISN mix together with RDF was profitable with a B: C ratio of 1.82 and 1.15, respectively. The effect of ISN mix on other crops and multiple cropping systems needs to be further studied.
