Abstract: A field experiment was conducted at the certified organic farm, Navsari Agricultural University, Navsari during rabi season of 2016-2017 to study the “Effect of organics on soil properties, growth, yield and quality of fenugreek (Trigonella foenum-graecum L.) grown under organic farming systemâ€. The treatment comprising three treatment of solid organics (S0: Control, S1: NADEP compost @ 5 t ha-1 and S2: Vermicompost @ 2.5 t ha-1) and four treatment of liquid organics (L0: Control, L1: Panchagavya @ 20 L ha-1, L2: Jeevamruta @ 200 L ha-1 and L3: Enriched banana pseudostem sap @ 5 L ha-1) were evaluated in Factorial Randomized Block Design with three replication on fenugreek variety “GM-2â€. The application of NADEP compost @ 5 t ha-1 recorded significantly higher soil organic carbon, available N, P2O5, K2O, DTPA-extractable Fe, Mn and Zn content, higher total fungi, total bacteria, Endophyte having PGPR activities (Pseudomonas fluorescens) and PSB (Bacillus megaterium) in soil and found statistically at par with treatment receiving vermicompost @ 2.5 t ha-1 except available N. However, significantly higher KMB (Frateuria aurantia) and free living N-Fixing Bacteria (Azotobacter croococum) with the application of vermicompost @ 2.5 t ha-1. In liquid organics, the application of enriched banana pseudostem sap @ 5 L ha-1 recorded significantly higher organic carbon, available N, P2O5, K2O and DTPA-extractable Fe and Mn content, higher total fungi, total bacteria, Endophyte having PGPR activities (Pseudomonas fluorescens) and free living N-Fixing Bacteria (Azotobacter croococum) in soil after harvest of fenugreek and stood at par with treatment L1 and L2 in case of available P2O5 and K2O and treatment L1 in case of Mn content in soil. However, significantly higher KMB (Frateuria aurantia) and PSB (Bacillus megaterium) with the application of Jeevamruta @ 200 L ha-1. The combined application of NADEP compost @ 5 t ha-1 and enriched banana pseudostem sap @ 5 L ha-1 (S1L3) gave significantly higher total fungi and Endophyte having PGPR activities (Pseudomonas fluorescens) but total bacteria was higher with treatment combination S1L1, S1L2, S1L3 and S2L3, and PSB (Bacillus megaterium) higher with treatment combination S1L2 and S1L3. Similarly, combined application of all liquid organics with NADEP @ 5 t ha-1 or vermicompost @ 2.5 t ha-1 gave significantly higher KMB (Frateuria aurantia) and free living N-Fixing Bacteria (Azotobacter croococum).
