Abstract:

An experiment was carried out at the Agronomy Field of Sher-e-Bangla Agricultural University, Dhaka during the period from March to June 2015 (Kharif-I season) to find out the effect of different manures along with inorganic fertilizers on yield and yield traits of mungbean varieties. The experiment consisted of two factors: factor A: five levels of manures along with inorganic fertilizers [ T0 = Control (no fertilizer or manure), T1 = Recommended dose of fertilizer (R) (45 kg urea ha-1 + 100 kg TSP ha-1 + 58 kg MoP ha-1), T2 = R + cowdung (3 t ha-1), T3 = R + poultry manure (2 t ha-1), T4 = R + vermicompost (2.5 t ha-1)] and factor B: two mungbean varieties; (V1 = BARI Mung 5 and V2 = BARI Mung 6). The experiment was laid out in split- plot design with three replications. The effect of manures along with recommended inorganic fertilizers on yield and yield traits were found significant. The maximum grain yield (1.53 t ha-1) and maximum stover yield (1.88 t ha-1) was recorded from T4 treatment. Mungbean variety had also significant influence on yield and yield traits. The maximum seed yield (1.58 t ha-1) was obtained from var. BARI Mung 6) but Maximum stover yield (1.91 t ha-1) was obtained from var. BARI Mung 5). The combined effects of manures along with recommended inorganic fertilizers and variety were found statically significant on yield and yield traits. The maximum seed yield (2.01 t ha-1) and maximum stover yield (2.61 t ha-1) was recorded from T4V2. There were positive correlations of seed yield with different yield components. It was comparatively stronger correlations in BARI Mung 5 and weaker in BARI Mung 6. So, var. BARI Mung 6 performed the best result with the application of vermi-compost @ 2.5 t ha-1 with recommended dose of fertilizer. Bangladesh Agron. J. 2017, 20(2): 115-122
