The study was undertaken to find out the optimum nutrient management practice of potato-mungbean-T. Aman rice cropping pattern to maximize yield realization and economic return by maintaining soil fertility and productivity. The experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur Gazipur, Bangladesh for 2 consecutive years during 2006-07 and 2007-08. Twelve nutrient management treatments were tested in RCBD with 3 replications. The highest potato tuber, mungbean seed and T. Aman rice yield were obtained from STB+CRI in both…mehr

The study was undertaken to find out the optimum nutrient management practice of potato-mungbean-T. Aman rice cropping pattern to maximize yield realization and economic return by maintaining soil fertility and productivity. The experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur Gazipur, Bangladesh for 2 consecutive years during 2006-07 and 2007-08. Twelve nutrient management treatments were tested in RCBD with 3 replications. The highest potato tuber, mungbean seed and T. Aman rice yield were obtained from STB+CRI in both the years. The nutrient balance was negative for N and K in all the treatments while the balances for P, S, Zn and B appeared positive in all the treatments except FP and control treatments in both the years. Properties of soil have been changed a little after completion of two cropping cycles in comparison to initial soil properties. Maximum gross return, gross margin and net return in STB+CRI (Tk.3,80,927 ha-1), (Tk.3,54,831 ha-1) and (Tk.2,77,172 ha-1), respectively. The highest BCR was observed in STB (3.69) followed by STB+CRI (3.67), IPNS (3.45) and IPNS+CRI (3.43).
