Integrated Nutrient Management on Productivity and Economics of Sugarcane under Three Agro-ecological Zones of Bangladesh

S.M. Bokhtiar, M.J. Alam, K. Mahmood and M.H. Rahman    

Abstract: Field experiments were conducted to study the effects of integrated plant nutrient system (IPNS) on the yield and yield contributing parameters of sugarcane at Ishurdi, Thakurgaon and Sreepur under High Ganges River Flood plain, Old Himalayan Piedmont Plain and Madhupur Tract, respectively. The use of organic and inorganic fertilizer showed significant effect on the yield and yield attributes like tillers, millable stalk and juice quality of sugarcane. The results revealed that yield increase was to the extent of 22.86, 49.2 and 74.0 % at Ishurdi, Thakuragaon and Sreepur, respectively due to the application of 12.5 t ha -1 press mud/cowdung accompanying chemical fertilizers applied on the basis of soil test for HYG over present recommended rates of chemical fertilizer (as per FRGĀ“97) for MYG. Press mud alone increased 16-20 per cent cane yield over the dose of N, P, K, S, Zn and Mg fertilizers based on soil test for HYG at all locations. Incorporation of dhaincha (Sesbania aculeata) as green manure increased cane yield and contributed about 42-46 kg N ha -1 in soil.
