Response of recommended dose of fertilizers with organic manures on growth, yield and economics of kalmegh (Andrographis paniculata Nees.): A way to reduced use of chemical Fertilizers

Background: Integrated application of nutrients is an important issue among the formers for obtaining higher growth and yield kalmegh. Nutrients must be accessible at right time, proportion quantity. Aim Objective: To fulfill these necessities, chemical fertilizers organic manures are required in integrated manner. Chemical have ensured readily availability particular nutrient initial but sources release slow long term many they improved efficacy reduced quantity fertilizers. Materials Methods: Therefore, fields study was taken up to bridge gap department Plantation, Spices, Medicinal Aromatic Crops, College Horticulture, RVSKVV, Mandsaur, (M.P.) during Kharif season 2021-22 RBD Design with three replications. The treatments accompanied RDF NPK @ 50:30:30 kg ha-1, FYM 7.5 & 15 T ha-1 vermicompost 0.5 1.0 along a control plot without any supplements. Results: result indicated that, significant maximum plant height, number branches, leaves, leaf area, area index, relative rate, crop biomass production different stages seeds per pod, pod length, dry weight, harvest herbage yield, seed cost cultivation, gross return, net return benefit: ratio were observed treatment T8-100% RDF+100% FYM+100% vermicompost. Conclusion: ha-1+100% t 1 found best achieving highest
