Department of Plantation, Spices, Medicinal and Aromatic Crops, ASPEE College of Horticulture and Forestry Navsari Agricultural University, Navsari-396 450, Gujarat Online published on 15 December, 2016. Abstract Investigations were carried out on Effect of integrated nutrient management on yield of kalmegh (Andrographis paniculata Wall. Ex. Nees.) at the Instructional Farm, Navsari Agricultural University, Navsari during the late kharif season of 2013–14. The experiment was conducted in Randomized Block Design with nine treatments viz., T1 (100% RDN from Vermicompost), T2 (100% RDN from Biocompost), T3 (100% RDNfrom Neemcake), T4 (100% RDN from Castor cake), T5 (50% RDN from Vermicompost + 50% RDN), T6 (50% RDN from Bio-compost +50% RDN), T7 (50% RDN from Neem cake + 50% RDN), T8 (50% RDN from Castor cake + 50% RDN), T9 [100% RDF (75: 40: 40 NPK kg/ha)] and all treatments were replicated thrice. All the yield attributes were found maximum in T3 treatment (100% RDN from Neem cake) fresh weight per plant (33.97 g), fresh weight per plot (4.14 kg), total herb yield (8511.7 kg), dry weight per plant (14.85 g), dry weight per plot (1.35 kg) and total dry matter production (2778.8 kg). From the economic point of view, maximum net realization of Rs. 36, 289.95 per hectare was recorded in T3 treatment (100% RDN from Neem cake) while in case of BCR it was maximum of 2.5 was in T2 treatment (100% RDN from Bio-compost). Thus, it can be concludedthat for obtaining higher profitable yield kalmegh be fertilized with 100% RDN (75 kg) from Neem cake under South Gujarat condition.
