Table 1 Effect of DHA and PA on growth of rice cv. BRRIdhan 28. The experiment was conducted in pots in a net house during the Boro season (January – April 2022). Plants were treated with DHA or PA alone or in combination as a foliar application or mock-treated with water or DMSO 15 days after transplanting (DAT) into the pots, followed by six spraying at 10 days intervals
