abstract
The pot experiment entitled “Management of cotton stalk residues through vermicomposting using the Epigeic earthworm” was carried out during the month of May to October, 2022 at Farm Shed, College of Agriculture, Navsari Agricultural University, Campus Bharuch, Gujarat, India. The experiment was laid out in Randomized Block Design (RBD), which included 9 treatments namely, T1: 50% CD + 50% CSR + EE, T2: 60% CD + 40% CSR + EE, T3: 70% CD + 30% CSR + EE, T4: 50% CD + 50% CSR + 10 g BBC + EE, T5: 60% CD + 40% CSR + 10 g BBC + EE, T6: 70% CD + 30% CSR + 10 g BBC + EE, T7: 50% CD + 50% CSR + 10 g BBC, T8: 60% CD + 40% CSR + 10 g BBC, T9: 70% CD + 30% CSR + 10 g BBC with three replication. Among different chemical properties of vermicompost, the different treatments do not differ significantly in respect of pH of the vermicompost at 90, 120 and 150 days whereas significantly lower pH was recorded in treatment T6 (70% CD + 30% CSR + 10 g BBC + EE) at 30 and 60 days. The significantly lower electrical conductivity was noted in treatment T3 (70% CD + 30% CSR + EE) which was 3.00 and 2.72 dS/m at 30 and 60 days, respectively. Whereas at 90, 120 and 150 days it was noted significantly lower in treatment T1 (50% CD + 50% CSR + EE) which was 2.41, 2.14 and 2.08 dS/m, respectively. The total organic carbon content (37.79%, 33.94%, 29.24%, 28.66% and 28.61%) in treatment T6 (70% CD + 30% CSR + 10 g BBC + EE) was found significantly lower at all recorded days which was found statistically at par with treatment T5 (60% CD + 40% CSR + 10 g BBC + EE) at 30, 60, 120 and 150 days.
