DEVELOPMENT OF FERTILIZER RECOMMENDATION FOR MUSTARD-BORO-T.AMAN RICE CROPPING PATTERN UNDER KARATOYA-BANGALI FLOOD PLAIN SOILS (Pages : 1 - 5)

An experiment was conducted at Gabtali, Bogra (AEZ-4) for three years (2001-2004) to determine the optimum fertilizer doses for Mustard-Boro-T. aman cropping pattern which enhanced total production and profit. Six nutrient management packages including one farmers’ practice and one control were tested. The other four treatments were soil test based (STB) fertilizer dose for moderate yield goals (MYG) and High yield goals (HYG), STB based fertilizer dose for HYG plus mustard oil cake (400 kg/ha) and fertilizer dose as per country’s Fertilizer Recommendation Guide (FRG’97). Three years average results of HYG gave higher yield performance of crops compared to the other treatments. The mean yield performance of treatment T2 (HYG) over three years of mustard, Boro and T. aman were 1.11, 5.59 and 3.39 t/ha, respectively. The average gross margin (Tk.17408/ha) and MBCR (3.77) of mustard was the highest in T2 (HYG). Similarly the highest gross margin (Tk .38597 /ha) and mean benefit and cost return (MBCR) (2.77) of Boro rice were observed from T2 (HYG). It was also observed that the highest gross margin (Tk .23718 /ha) and MBCR of T. aman obtained from T2.Download
