The field experiment was conducted at College of Horticulture, Mudigere, to study on influence of planting density and fertilizers on growth and development of tissue culture banana cv. Ney poovan (AB) under hill zone of Karnataka during 2017-2018 with Factorial Randomized Block Design. The treatments were replicated twice with three factors and three levels. First spacing S1- 2.0 x 2.0 m, S2- 3.0 x 2.0 m and S3-2.0 x 4.0 m, second plant density D1- single plant per pit, D2- double and D3-triple plants per pit and third factor fertilizers F1-100% RDF, F2-125% RDF and F3-150% RDF. The results revealed that, as influenced by different levels of spacing, plant density and fertilizers on plant and ratoon crop of banana. The maximum pseudostem height of plant and ratoon crop was recorded in S1 (310.26 and 304.47 cm) at shooting stage and plant density in D3 (310.44 and 309 cm). The pseudostem girth and number of leaves was recorded maximum in S3 at 5th MAP (30.78 and 27.41 cm), (11.52 and 10.49) and in plant density was D1 at 5th MAP (31.85 and 28.24 cm)(11.88 and 11.04) and shooting stage (62.61 and 60.18cm) and 18.39 and 17.32) of plant and ratoon crop. Whereas in fertilizer (F3) was recorded maximum number of leaves at 5th MAP (11.54 and 10.57). The absolute growth rate for pseudostem height was maximum in D2 during 3rd to 5th MAP (1.04 cm day-1). The maximum number of suckers production per pit of plant and ratoon crop was obtained in S3 at 7th MAP (6.52 and 7.24) and shooting (9.04 and 8.32). with respect to plant density highest suckers production was registered in D1 at shooting (8.33). Whereas in fertilizer levels, the maximum number of suckers (6.75 and 8.04) was found in F3. While interactions the treatment S3D1 recorded the maximum suckers per pit at shooting (10.07 and 8.88) in plant and ratoon crop.
