dc.description.abstract The experiment was conducted during the period of October 2017 to February 2018 in the Research farm of Sher-e-Bangla Agricultural University, Sher-eBangla Nagar, Dhaka-1207 to find out the effect of humic acid and salicylic acid on morphology and yield of mustard. BARI Sarisha 15 was used as planting material in this experiment. The experiment comprised of two factors- Factor A: Levels of humic acid (HA): 4 levels - i) HA 0 ii : 0 kg/ha (control), ii) HA 1 : 8.0 kg/ha, iii) HA 2 : 16.0 kg/ha, iv) HA 3 : 24.0 kg/ha and Factors B: Levels of salicylic acid (SA): 4 levels - i) SA 0 : 0 mM SA (control), ii) SA 1 : 0.2 mM SA, iii) SA 2 : 0.4 mM SA, iii) SA 3 : 0.6 mM SA. The two factors experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data were recorded on different morphological characters, yield contributing parameters and yield of mustard and significant variation was observed for different treatments. For humic acid, at 30, 40, 50, days after sowing (DAS) and at harvest, the tallest plant (63.35, 85.31, 97.21 and 103.99 cm, respectively) was recorded from HA 3 , whereas the shortest plant (57.77, 75.02, 86.91 and 94.83 cm, respectively) from HA 0 . The highest number of siliqua (48.26) was recorded from HA 3 , whereas the lowest number (40.21) from HA 0 . The highest seed yield (1.89 t/ha) was recorded from HA 3 , whereas the lowest (1.34 t/ha) from HA 0 . In case of levels of salicylic acid, at 30, 40, 50 DAS and at harvest, the tallest plant (64.22, 89.09, 101.43 and 108.24 cm, respectively) was recorded from SA 3 , while the shortest plant (55.91, 71.20, 80.88 and 89.54 cm, respectively) from SA 0 . The highest number of siliqua (47.36) was recorded from SA 3 , while the lowest number (40.11) from SA 0 . The highest seed yield (1.79 t/ha) was recorded from SA 3 , while the lowest (1.36 t/ha) from SA 0 . Due to the interaction effect of different levels of humic acid and salicylic acid, at 30, 40, 50 DAS and at harvest, the tallest plant (69.77, 96.82, 111.49 and 114.98 cm, respectively) was found from HA 3 SA 3 and the shortest plant (52.11, 62.00, 72.91 and 83.78 cm, respectively) from HA 0 SA 0 . The highest number of siliqua (52.07) was found from HA 3 SA 3 and the lowest number (32.00) from HA 0 treatment combination. The highest seed yield (1.97 t/ha) was found from HA 3 and the lowest (1.06 t/ha) from HA 0 SA 0 treatment combination. Among the combination of different levels of humic acid and salicylic acid, 24.0 kg/ha humic acid with 0.6 mM salicylic acid induced superior growth, yield contributing characters and yield of mustard. en_US
