Abstract
The field experiment was conducted to study the “Effect of organic nutrient management in growth and physiological parameters of redgram (Cajanus cajan L.) and executed during rabi season 2023 - 2024 at North farm, Karunya Institute of Technology and Sciences, Coimbatore. The experiment was laid out in randomized complete block design with 11 treatments and 3 replications. The result revealed that maximum plant height, number of root plant-1, dry matter production, leaf area index, crop growth rate, relative growth rate, net assimilation rate was found higher in 50% N equivalent based FYM @ 2.5 t ha-1 + 50% N equivalent based vermicompost @ 0.416 t ha-1 (T4) and 100% RDF + FYM @ 12.5 t ha-1 (T10) and which was followed by 100% N equivalent based vermicompost @ 0.8 t ha-1 compared to control (T11). As the result from the study recorded and concluded that the interaction effect with 50% N equivalent based FYM @ 2.5 t ha-1 + 50% N equivalent based vermicompost @ 0.416 t ha-1 increases the crop growth and physiological parameters of redgram and results in higher production.
