Abstract
An investigation was conducted in Rabi season of 2023-24 at the instructional farm of Karunya Institute of Technology and Sciences, Coimbatore, to evaluate the performance of physiological indices on chickpeas under soil and foliar application. The experiment was established on a Factorial Randomized Block Design (FRBD). The treatments were soil application of NPK 100 percent (A1), NPK 100 percent + FYM 10 t ha-1 (A2), NPK 100 percent + Vermicompost 5 t ha-1 (A3), NPK 75 percent + FYM 10 t ha-1 (A4) and NPK 75 percent + Vermicompost 5 t ha-1 (A5) combined with foliar applications, viz., Nano-DAP (B1) and Nano-Urea (B2). The results of the study revealed that morpho-physiological attributes of chickpeas were statistically increased by the application of soil (NPK 75 percent + Vermicompost 5 t ha-1) combined with foliar (Nano-urea) nutrient management practices resulting in maximum grain yield of 15.64 q ha-1 and stover yield of 30.49 q ha-1. The results of this study underscore the importance of integrated nutrient management practices involving soil and foliar applications in enhancing the physiological indices of chickpeas.
