Abstract
Growth, phosphorus uptake and bunch yield of banana cv. Robusta grown under high density planting were studied on a sandy clay loam (Udic Paleustalf) soil at ICAR-Indian Institute of Horticultural Research, Bangalore using 32P labelled super phosphate with application of three levels viz., 60, 80, and 100 per cent of recommended dose of phosphorus in three different placement viz., 15-35, 35-55 and 55-75 cm distance from pseudostem of the plant. The results on vegetative growth parameters revealed that the maximum plant height (212.4 cm) and girth (63.40 cm), highest number of functional leaves (16.3) and total leaves (29.70) and early flowering (295 days) and harvesting (431 days) were recorded with application of 100 per cent recommended dose of P at band width of 20 cm around the plant between 35 to 55cm. From the specific activity of 32P found in leaves, highest Pdff (12.26%), total P uptake (16.0 g plant-1 and 71.13 kg ha-1) and fertilizer P uptake (1.96 g plant-1 and 8.72 kg ha-1) were recorded with application of 100 per cent recommended dose of P fertilizers in the distance of 35-55 cm from the pseudostem of the experimental plant. Higher dry matter production (7.31 kg plant-1 and 32.49 t ha-1), bunch weight (22.17 kg) and bunch yield (98.51 t ha-1) of ‘Robusta’ banana was recorded with 100% recommended phosphorus dose and found to be on par with 80% recommended phosphorus. Among the placements, the application of fertilizers between 35 and 55 cm distances yielded highest bunch weight, bunch yield and dry matter production. Application of fertilizer at the farthest distance between 55 and 75 cm distances was distinctly inferior showing that there is little scope of application of fertilizers between the rows under the high density planting of banana and it is best to apply fertilizer in a circular strips between 15 and 55 cm distances at 5 cm depth.
