    EFFECT OF COMBINED APPLICATION OF VERMICOMPOST AND NPK FERTILIZERS ON THE YIELD OF MUNGBEAN
    (Dept. of Soil Science, Sher-e-Bangla Nagar, Dhaka, Bangladesh, 2007-12) HASAN, MOHAMMAD MAHMUDUL
    A field experiment was conducted at the Shcr-e-I3angla Agricultural University Farm, I)haka 1207 during the Kharif season of 2007 to study the effect of vermicompost and NP}C fertilizers on the yield of mungbean. The experimental soil was silty clay loam in texture having pH of 6.0. The treatments were 4 levels of vermicomposts viz. V0 (0 hi'). V, (It hi'). V2 (2 t hi').V3 (4 tha4). and 3 levels of chemical fertilizers viz. F0 = (0-0-0 kg ha'), F, = medium (10-10-14 kg hi'). F2 = high (20-20-28 kg ha4) of N-P-K with 12 treatment combinations and 3 replications. The results showed that with the increasing the doses of vermicompost and chemical fertilizers grain and straw yields of mungbean were increased significantly. The maximum significant grain and straw yields were obtained with the treatment combinations V3F,. The highest doses of vermicompost and chemical fertilizers increased N. P and K concentrations in mungbcan plant significantly at maturity stage. Application of vermicompost and chemical fertilizers increased organic carbon, N, P and K status of postharvest soil significantly.
