Integrated use of organic manure and chemical fertilizer on growth, yield, and quality of sugarcane in High Ganges River Floodplain soils of Bangladesh.

Abstract A study was undertaken to evaluate the effects of integrated use of organic wastes such as press mud, farmyard manure (FYM), and green manure (Crotalaria juncea) along with chemical fertilizer on the yield and quality of sugarcane in High Ganges River Floodplain soils of Bangladesh. Chlorophyll a and Chlorophyll b contents of cane leave tissues were slightly increased by organic manure and green manure. Leaf area index (LAI) and total dry matter (TDM) production were higher during rapid grand growth phase. Application of fertilizer (based on soil test value) accompanied with FYM at 15 t ha−1 produced the maximum plant population density of 163.4×103 ha−1 and resulted in the highest cane and sugar yields of 108.4 and 9.47 t ha−1, respectively. The phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), copper (Cu), iron (Fe), zinc (Zn), and manganese (Mn) contents in leaves were higher in organic manured plots over chemical fertilizer. The organic matter, total nitrogen (N), available P, K, a...
