Effect of Foliar Application of Salicylic Acid and Naphthalene Acetic Acid (NAA) on Growth and Yield Parameters of Mungbean (Vigna radiata L.)

Abstract

The present study aimed to investigate “Effect of foliar application of Salicylic acid and Naphthalene Acetic Acid (NAA) on growth and yield parameters of Mungbean (Vigna radiata L.)”. This research was conducted during the kharif season 2018 at the Student Instructional Farm (SIF) of Narendra Deva University of Agriculture & Technology in Kumarganj, Ayodhya. The experiment followed a randomized block design (RBD) with three replications and involved seven treatments. The Mungbean variety used in the study was Narendra Mung-1 (NDM-1). Seven treatments as comprised of T1 - control (distilled water spray at 30 & 40 DAS), T2 - foliar spray of SA @ 50 ppm at 30 DAS, T3 - foliar spray of SA @ 80 ppm at 30 DAS, T4 - foliar spray of NAA @ 50 ppm at 30 DAS, T5 - foliar spray of NAA @ 80 ppm at 30 DAS, T6 - foliar spray of NAA @ 50 ppm at 40 DAS, T7 – Foliar spray of NAA @ 80 ppm at 40 DAS. The results indicated that the treatment T5 (foliar application of NAA @ 80 ppm at 30 DAS) showed significant increase on growth parameters like plant height (cm), total number of branch plant-1, total dry biomass (g) plant-1 and yield & yield attributes like number of pods clusters-1, number of pods plant-1, pod length (cm), number of seeds plant-1, number of seeds pod-1with T5, followed by T7 treatment (foliar application of NAA @ 80 ppm at 40 DAS), respectively over the control.
