Abstract: A field experiment was conducted during 2019 in the western agro-climatic zone, Tamil Nadu with the objectives of studying the effect of post shooting foliar spray on yield attributes, yield and economics of tissue culture nendran banana. The experiment was laid out in a randomized block design and replicated four times. Six treatments comprising of three potassium containing nutrient spray (Potassium dihydrogen phosphate, potassium sulphate and potassium silicate), two plant growth regulators (gibberellic acid and brassinosteroid) were tested. Besides, control (water spray) (T₁) was considered as the benchmark for ascertaining the performance of other treatments. The results revealed that foliar spray of gibberellic acid at 100mg/l (T₅) recorded higher finger length (30.2 cm), finger circumference (16.0 cm), finger weight (296.3 g), pulp weight (217.6 g), peel weight (76.1 g), pulp peel ratio (2.86), bunch weight (27.1 kg/bunch), yield (61.4 t/ha) and higher B:C ratio (4.42) in tissue culture nendran banana.
