Effect of integrated nutrient management on growth and yield of japanese mint (Mentha arvensis L.)

Japanese mint (Mentha arvensis L.) is one of the important commercial and essential oil bearing industrial crop cultivated in Punjab. Integrated nutrient management is an important approach to use the organic manure with optimum level of NPK fertilizers, as it will not only improve the growth status, but also sustained the crop yield. Field experiment was conducted at Campus for Research and Advanced Studies, Dhablan, G.S.S.D.G.S. Khalsa College, Patiala during Rabi season of 2017–18 in randomized block design with three replications. Above all the treatments, the highest growth and yield was recorded in the treatment Tu (50% NPK + 2 tonne FYM + 1 tonne vermicompost + 1 tonne poultry manure) and this treatment was statistically at par with the treatment T₁₀ (50% NPK + 1 tonne vermicompost + 1 tonne poultry manure).
