Abstract:
At Research farm of Agricultural Botany section, College of Agriculture, Nagpur a field experiment was conducted during Kharif 2022. The experiment was carried out in RBD with three replication which constitute of ten number of treatments. The treatments were 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 untreated control and spraying was done at 25 DAS. Foliar application of salicylic acid and gibberellic acid sprayed at 25 DAS revealed the result that significantly improved growth parameters like plant height, number of branches plant^-1, days to 50 percent flowering, total dry weight, leaf area and yield parameters like number of pods plant^-1, test weight, seed yield ha^-1, harvest index and B:C ratio. Treatment T₆ (Gibberellic acid @ 200 ppm) gave significantly higher results in plant height, total dry weight and leaf area and T₅ (Gibberellic acid @ 150 ppm) in number of branches plant^-1 and days to 50 percent flowering. Treatment T₉ (Salicylic acid @ 150 ppm) shows significantly higher results in all parameters of yield.
