ABSTRACT

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).
