Effect of Organic Manures and Foliar Application on Growth, Yield and Nutrient Uptake of Kalmegh (Andrographis paniculata Nees.) Nadhiya Devi K S. Sivasankar M. Kumaresan VA. Abhirami K. Khanchana

A field experiment was carried out to study the effect of organic manures and foliar application of organics on growth, yield and nutrient uptake of Kalmegh at the Department of Horticulture, Faculty of Agriculture, Annamalai University to find out the suitable organic inputs and foliar organics for better growth, yield and nutrient uptake of Kalmegh. The experiment was laid out in a Randomized Block Design with twelve treatments and three replications comprising of a different combination (i) basal organics viz., Farm Yard Manure, Vermicompost and Pressmud (ii) foliar spray of organics viz., Panchagavya and Fish Amino Acid and untreated control. Among the twelve treatments, the plants which received Vermicompost at 5 t ha-1 + fish amino acid at 3% expressed higher values for the growth parameters viz., plant height (69.80 cm), number of branches plant-1 (25.13), number of leaves plant-1 (140.87). Physiological parameters viz., leaf area plant-1 (6.78), total dry matter production plant-1 (15.86 g plant-1). Yield parameters viz., fresh herbage yield plant-1 (42.74 g plant-1) and dry herbage yield plant-1 (14.24 g plant-1). Nutrient uptake viz., Nitrogen (38.97 Kg ha-1), Phosphorous (6.87 Kg ha-1) and Potassium (84.23 kg ha-1).
