The experiment on the effect of organics, Azospirillum (Root and soil isolate) and Humic acid on growth and leaf yield in Gymnema (Gymnema sylvestre R.Br) was carried out at the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar. There were totally 13 treatments viz., T1- Vermicompost 1Kg + Azospirillum (RI) 10 g/plant + Humic acid 0.1% (soil application),T2- Decomposed Coir pith 5 kg + Azospirillum (RI) 10 g/plant + Humic acid 0.1% (Soil application),T3- Vermicompost 1Kg + Azospirillum (RI) 10 g/plant + Humic acid 0.2% (soil application),T4- Decomposed Coirpith 5 kg + Azospirillum (RI) 10 g/plant + Humic acid 0.2% (Soil application),T5- Vermicompost 1Kg + Azospirillum (RI) 10 g/plant + Humic acid 0.3% (soil application),T6- Decomposed Coirpith 5 kg + Azospirillum (RI) 10 g/plant + Humic acid 0.3% (Soil application),T7- Vermicompost 1Kg + Azospirillum (RI) 10 g/plant + Humic acid 0.1% (Foliar application),T8- Decomposed Coirpith 5 kg + Azospirillum (RI) 10 g/plant + Humic acid 0.1% (Foliar application),T9- Vermicompost 1Kg + Azospirillum (RI) 10 g/plant + Humic acid 0.2% (Foliar application),T10- Decomposed Coirpith 5 kg + Azospirillum (RI) 10 g/plant + Humic acid 0.2% (Foliar application),T11- Vermicompost 1Kg + Azospirillum (RI) 10 g/plant + Humic acid 0.3% (Foliar application),T12- Decomposed Coirpith 5 kg + Azospirillum (RI) 10 g/plant + Humic acid 0.3% (Foliar application),T13- Control (Native soil).There were established in the field and observed for certain growth characters like Plant height, Number of laterals /plant, Number of leaves/lateral, Leaf length (cm),Leaf breadth(cm),Leaf area(cm2),Single leaf weight(gm.),100 Leaves weight(gm.),Fresh leaf yield/ plant(gm.) and dry leaf yield were recorded four months of planting. The Treatment, T9- Vermicompost 1Kg + Azospirillum (RI) 10 g/plant + Humic acid 0.2% (Foliar application), recorded highest plant height (299.94), Number of laterals/plant (47.54), Number of leaves/lateral (128.93), Leaf length (7.79cm), Leaf breath (5.86cm), Leaf area (18.39cm2), Single leaf weight (0.44gm.), 100 leaves weight (44.84gm.), Fresh leaves yield/plant (4.38kg.) and Dry leaves/plant(2.78kg.). This was followed by T10- Decomposed Coirpith 5 kg + Azospirillum (RI) 10 g/plant + Humic acid 0.2% (Foliar application).
