Medicinal coleus (Coleus forskohlii Briq.) is one of the commercial Indian medicinal herb. It plays an important role in medicinal industry. The demand of tuberous roots is very high, but the productivity is very low. Therefore the integrated nutrient management could help in achieving higher growth in medicinal coleus. Thus, an experiment was conducted to know the “Effect of Integrated nutrient management on growth of medicinal coleus (Coleus forskohlii Briq.)” at Sirukalathur village, Ariyalur District - Tamilnadu during the year 2018-2020. A field experiment was consist of different combination of nutrients viz., recommended dose of fertilizers, farmyard manure, neem cake, castor cake and bio-fertilizers (Azospirillum and Azotobacter). The experiment was laid out in randomized block design with 10 treatments and three replications. Among these various treatments tried, plants supplied with T5 (75 % RDF + FYM @ 15 t ha-1 + Castor cake @ 2 t ha-1 + Azotobacter @10 kg ha-1) was recorded maximum growth parameters viz., plant height, number of branches plant-1, plant spread, number of leaves plant-1, leaf area plant-1, LAI, fresh and dry weight of leaves and shoots plant-1 and dry matter production
