    EFFECT OF COMBINED APPLICATION OF ORGANIC AND INORGANIC FERTILIZER ON GROWTH AND YIELD OF MUNGBEAN
    (DEPARTMENT OF SOIL SCIENCE, SHER-E-BANGLA AGRICULTURAL UNIVERSITY, SHER-E-BANGLA NAGAR, DHAKA, 2020-12) HARUN-UR-RASHID, MD.
    A field experiment was conducted at the Sher-e-Bangla Agricultural University farm, Dhaka 1207 during the Kharif-1 season from June 2019 to August 2019 to study the effect of organic and inorganic fertilizers on the growth and yield of mungbean . The experimental soil was silty clay loam in texture having p H 6.1.The experiment was laid out in Rendomized Complete Block Design (RCBD) with 3 replication .There were 7 treatment where , T 1 = 100% Recommended chemical fertilizer + 0 t/ha vermicompost , T 2 =75% Recommended chemical fertilizer + 2 t/ha vermicompost, T 3 = 75% Recommended chemical fertilizer + 3 t/ha vermicompost, T 4 = 75% Recommended chemical fertilizer + 4 t/ha vermicomost, T 5 = 50% Recommended chemical fertilizer +2 t/ha vermicompost, T 6 =50% Recommended chemical fertilizer + 3 t/ha Vermicompost, T 7 = 50% Recommended chemical fertilizer +4t/ha vermicompost . In case of inorganic fertilizer levels are contained 50% level of NPK= (10-10-14 kg/ha ) , 75% level of NPK=(15-15-21 kg/ha ) , 100% level of NPK =(20-20-28 kg /ha ) .Different plant growth and yield parameters were significantly influenced by different organic and inorganic level of fertilizer . Application of 75% recommended inorganic fertilizer and 4 t/ha vermicompost in case of T 4 treatment was recorded the maximum plant height (58.26 cm) , number of branches /plant (1.72) , pod length (9.49) , grain yield (1.54t/ha) , and straw yield ( 2.63 t/ha) and the minimum plant height(51.50 cm) , number of branches /plant (0.95) , number of pods /plant (13.16) , number of seeds /pod (10.23) , grain yield ( 0.78 t/ha) and straw yield ( 1.66 t/ha) was recorded from the T 1 treatment where only 100% recommendation chemical fertilizer was used.. The maximum significant grain and straw yields were obtained with the treatment combination T 4 (where, 75% recommended chemical fertilizer + 4 t/ha vermicompost). The minimum yield of grain and straw yield were obtained with the treatment combination T 1 (100% recommended chemical fertilizer + 0 t/ha vermicompost).
