Field experiment was conducted to study the influence the spacing and organics on leaf nutrient status of Solanum nigrum. The experiment was laid out in a split plot design with three replications. The treatments consisted of four levels of spacing (M1-30 x 30cm, M2-45 x 45cm, M3-60 x 30cm and M4-60 x 45cm) and nine bio-stimulants/organics (S1-Recommended dose of fertilizer (RDF), S2-control, S3-panchagavya 2 per cent, S4-panchagavya 3 per cent, S5-moringa leaf extract 2 per cent, S6-moringa leaf extract 4 per cent, S7-humic acid, S8-cytozyme 1 per cent and S9-vermicompost). The results revealed that, the treatment with wider spacing + RDF (M4S1) recorded the highest leaf Nitrogen (2.84 per cent) and Phosphorous content followed by the treatment Wider spacing + panchagavya (M4S4) (Nitrogen content-2.63 per cent and Phosphorous content-0.25 per cent). Regarding the leaf potassium content the treatment wider spacing + RDF (M4S1) combination recorded the highest leaf K content (2.72 per cent) followed by the treatment wider spacing + humic acid combination (M4S7) (2.57 per cent).
