Abstract
Field experiment was conducted at the BINA Sub-Station, Ishurdi to investigate the integrated effect of vermicompost and chemical fertilizers on the yield and yield contributing characters of brinjal. Seven treatments were used in the experiment. The treatments used in the experiments were T1: Control; T2: Recommended fertilizer (RF); T3: 75% RF + 3 tha-1 Vermicompost (VC); T4: 75% RF + 5 tha-1 VC; T5: 50% RF + 3 tha-1 VC; T6: 50% RF + 5 tha-1 VC; T7: 5 tha-1 VC. The experiment was conducted in a Randomized Complete Block Design with three replications. The treatment T4 (75% RF + 5 tha-1) gave maximum yield (7.8 tha-1) of brinjal followed by the treatment T6 (6.88 tha-1). But the treatments T3 and T5 gave identical yields of brinjal. Therefore, fertilizer doses of N101.25, P27, K52.5, S3.75, Zn0.75 kgha-1 with VC @ 5 tha-1 for Ishurdi could be adopted in the cultivation of brinjal for getting maximum yields.
