To study the major nutrient uptake of medicinal coleus influenced by different organic manures equivalent to 100 per cent recommended dose of nitrogen through FYM, vermicompost, poultry manure, neem cake, pressmud and pongamia cake and RDF. Use of FYM equivalent to 100 per cent RDN resulted in higher N uptake in leaf (81.15 kg/ha), tubers (4.98 kg/ha), total uptake (169.89 kg/ha), P uptake in leaf (23.44 kg/ ha), tubers (1.33 kg/ha) and K uptake in leaf (71.38 kg/ha), tubers (4.09 kg/ha) were recorded. Whereas, K uptake by stem (91.39 kg/ha), total uptake of K (168.19 kg/ha) and highest available N were also observed in the above treatment. Total dry matter production (467.70 g/plant) and P uptake in stem (26.33 kg/ha) and total uptake of P (49.46 kg/ha) were recorded in T7-RDF (50:50:50 kg NPK/ha + FYM 10 t/ha) treatment.
