The field experiment was conducted at the Bidhan Chandra Krishi Viswavidyalaya, West Bengal to study the effect of drip fertigation on the plant morphology and crop duration of banana (cv. Martaman-AAB group) in an alluvial soil during 2012 and 2013. The drip fertigation was done at four evapotranspiration (ET) based irrigation levels (D1=0.6 ET, D2=0.8 ET, D3=1.0 ET for drip and surface irrigation (S) at IW/CPE 1.0 and at three fertilizer levels of recommended doses of fertilizer (RDF) viz., F1=60% RDF, F2=80% RDF and F3=100% RDF laid out in factorial randomized block design with three replications. In juvenile, vegetative and shooting stages the treatment, D3F3 registered maximum pseudostem height (100.3, 204.6 and 308.8 cm), pseudostem girth (36.1, 66.3 and 81.7 cm), leaf breadth (44.5, 56.5 and 62.3 cm), leaf area (107.5, 153.6 and 189.2 cm), LAI (0.97, 2.13 and 3.53) and number of leaves (8.5, 11.8 and 13.3). The D3 level of drip irrigation shortened 18.0, 10.9 and 28.9 days to shooting, bunch harvest and total crop duration, respectively as compared with surface irrigation. The crop duration was shortest for combination D3F3 as compared with other treatment combinations, whether drip or surface irrigation.
