Abstract

In Kharif 2022, a field experiment was conducted at Research farm of Agricultural Botany section, College of Agriculture, Nagpur. The experiment was laid out in RBD with three replications consisting often treatments. The treatments composed of foliar spray of two plant growth regulators of different concentrations viz., Gibberellic acid (50 ppm, 100 ppm, 150 ppm and 200 ppm) and Salicylic acid (50 ppm, 100 ppm, 150 ppm and 200 ppm) along with control spraying was done at 25 DAS. Results showed that foliar application of salicylic acid and gibberellic acid sprayed at 25 DAS significantly improved biochemical parameters like nitrogen content in leaves, protein content in seed, total chlorophyll content in leaves and yield parameters like number of pods plant-1, test weight, seed yield ha-1, harvest index and B:C ratio. Treatment T9 (Salicylic acid @ 150ppm) showed significantly higher results in all parameters under study. Effect of salicylic acid and gibberellic acid application was influenced by various environmental conditions and for accurate conclusion it is essential to understand the sensitivity of the black gram variety to prevailing conditions. The timing of salicylic acid and gibberellic acid application is critical and sophisticated analytical techniques are required for accurate measurement of biochemical parameters. To overcome these challenges, well-controlled experiments should be designed by considering multiple factors in collaboration with experts in plant physiology and biochemistry.

Keywords

Vigna mungo, salicylic acid, gibberellic acid, biochemical parameters, yield contributing parameters, growth regulators

Conclusion

Application of Salicylic acid @ 150 ppm showed highest result in biochemical and yield parameters. The application of foliar nutrition helps to overcome the specific occurrence of stress and as a result of maximum vegetative growth due to optimized nutrition of the plant.
