A field experiment was conducted at University Orchard, Horticultural College and Research Institute, Coimbatore to standardize the cropping density and nutrient requirement on growth and development of banana cv. Quintal Nendran (AAB) during 2015-17. The studies were carried out by planting banana suckers at three spacing levels viz., S1–1.8x1.8 m (3086 plants ha-1), S2 - 2.1 x 2.1 m (2267 plants ha-1), S3 - 2.1 x 2.4 m (1984 plants ha-1) with four fertigation levels viz., F1 - 75 per cent, F2 - 100 per cent, F3 - 125 per cent and F4 - 150 per cent RDF. The results revealed that plant density and fertigation influenced growth and development of banana cv. Quintal Nendran. The lowest pseudostem height (294.44 and 300.86 cm) at shooting stage was recorded in spacing (S3), fertigation (F1) compared to other treatments. The lowest absolute growth rate (AGR) for pseudostem height (0.843 cm day-1and 0.870 cm day-1) during 9 month after planting (MAP) to shooting stage was recorded in S3 spacing and F1 fertigation. The highest pseudostem girth (68.48and 71.15 cm) at shooting stage was recorded in spacing (S2), fertigation (F3) and their interaction (S3F3) treatment (73.10 cm). The highest absolute growth rate for pseudostem girth was recorded in wider spacing (S2 and S3). The wider spacing (S3) and higher level of fertigation (F4) registered more number of suckers (7.09 and 6.90).
