Abstract
A field experiment was conducted at the BINA substation farm, Ishwardi, Pabna during 2021- 2022 to see the combined effects of vermicompost and inorganic fertilizer (Urea, TSP, MoP, gypsum, zinc and boron) on sesame growth and yield. Five treatments combination were used in the experiment. The treatments were T1=Native soil fertility (No fertilizer and manure), T2=100% Chemical Fertilizers (CF), T3= Vermicompost (VC) @ 5 ton/ha, T4=50% CF + 2.5 ton/ha VC, T5=70%CF + 1.5 ton/ha VC. Yield and yield contributing characters of sesame were significantly influenced with the different treatments. The treatment T4 (50% CF + 2.5 tha-1 VC) gave the highest seed yield of sesame. The results indicated that treatment T4 enhanced more crop growth which influenced on greater seed yield of sesame. The lowest seed yield was recorded at T1 treatment. However, considering maximum yields the treatments T4 could be used for more production of sesame with less use of chemical fertilizers.
