Sindh is the major banana growing province in Pakistan with potential for improving yields through proper nutrient management. This study investigated the influence of integrated use of the organic amendments farmyard manure (FYM) and composted pressmud (CPM) and six mineral fertilizer treatments (500:0:0, 500:125:0, 500:187.5:0, 500:250:0, 500:250:500, 625:312.5:0 kg N: P2O5: K2O ha-1 , respectively, designated as N, NP0.5, NP0.75, NP1.0, NPK and 1.25NP (1.25 times of N and P) on the growth and yield of banana. The application of P and K fertilizers as well as the organic amendments produced significant increase in banana stem girth, number of functional leaves/plant and yield over that obtained with N alone. The effect of fertilizers became more prominent with time such that the application of either NP0.75 or NP1.0 produced significant increase in the growth parameters over that obtained with N only. In case of yield, the values increased by 22.6% with FYM (35.0 to 42.9 t ha-1 ) and by 18.9% with CPM (35.0 to 41.6 t ha-1 ) over no organic amendment treatments. Banana yield increased by 16.8% (31.6 to 36.9 t ha-1 ) when P and K fertilizers were also applied (NPK treatment). Similarly, when FYM was added to N alone treatment, yield increased by 19.9% (31.6 to 37.8 kg ha-1 ). When FYM was used in conjunction with NPK, the yield increased over N alone treatment by 59.4% (31.6 to 50.3 t ha-1 ). The two organic sources produced similar results and that sub-optimal rates of P performed better when used along with FYM or CPM as compared to NPK or 1.25NP treatments alone
