    TOXIC EFFECT OF CHROMIUM ON GROWTH, YIELD AND NUTRITIONAL ATTRIBUTES OF BRRI dhan69 and BRRI dhan74
    (DEPT. OF AGRICULTURAL CHEMISTRY, 2017) ISLAM, MOMENUL
    The experiment was conducted at the net house of Agro-environmental Chemistry laboratory of department of Agricultural Chemistry of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from December 2016 to May 2017 to study the toxic effect of chromium on growth, yield and nutritional attributes of BRRI dhan69 and BRRI dhan74. The experiment comprised of two factors, Factor A: two rice cultivars i.e. V 1 = BRRI dhan69, V 2 = BRRI dhan74; and six levels of Cr application i.e. T 1 = 0 mg Cr/kg soil, T 2 = 12.5 mg Cr/kg soil, T 3 = 25 mg Cr/kg soil, T 4 = 50 mg Cr/kg soil, T 5 = 75 mg Cr/kg soil, T 6 =100 mg Cr/kg soil. The experiment was laid out in Completely Randomized Design (CRD) with four replications. Data on different growth parameters, yield attributes, yield and biochemical properties were recorded and analyzed. Data revealed that Cr absorbed by both variety where V 2 absorbed maximum amount of Cr than V 1 . Therefore, the control treatment attributed the highest values of vegetative growth, yield and yield contributing character, and nutrient content with V 2 variety. The combination of V 2 gave the best result for all vegetative, reproductive growth parameters and nutrient content of rice. Thus, variety V 2 is recommended in Cr rich soil for the minimum absorption of Cr by the variety V 2
