• Abstract : India produces 30 million tons of banana from 8 lakh hectares, annually. It is estimated that India has to produce 50 million tons of banana to meet out the domestic and export needs for banana, in 2030 AD. Banana production systems at the current level of yields are not found to be sustainable, in the long run, as there is significant mining of plant nutrients in soil and imbalanced fertilization. High yielding, fertilizer responsive varieties of banana and escalating costs of fertilizers have necessitated the development of a quantitative basis for making fertilizer recommendations according to soil fertility status of field for obtaining economic yield of banana. Therefore, soil test crop response studies based on soil fertility gradient approach were carried out on 'Grand Naine' (AAA) banana, which is commercially important in India. Fertilizer adjustment equations and ready-reckoners were developed and they were validated in the farmers' fields in two different locations (Pazhur and Sirugambur villages), in Tiruchirapalli district of Tamil Nadu. In response to the yield, these fertilizer tailoring equations hold good up to the target 105 t/ha and 120 t/ha, under Pazhur and Sirugambur soil conditions, respectively. Beyond these targets, the actual yields increased with diminishing rate and with increasing B: C ratio up to the yield target, 135 t/ha, in both the villages. The levels of NPK required to achieve these targeted yields were found to be optimum for sustaining soil health, while the adhoc recommendation of 200: 30: 350 g N: P2O5: K2O/plant recorded 100.2 t/ha and 99.7 t/ha in Pazhur and Sirugambur, respectively.
