Background: Pearl millet [Pennisetum glaucum (L.) is a significant food and livestock crop in the semi-arid tropics. Pearl millet is a crucial part of the nation's food security because of its capacity to thrive in drier and less fertile regions, where other grains have a comparative disadvantage.

Objectives: Effect of potassium and plant growth regulators on growth parameters and yield of pearl millet

 Methods: With the goal of the study effect of potassium and plant growth regulators on growth and yield of Pearl millet (Pennisetum glaucum L.) Var. NBH- 5658 under a Randomized block design(RBD) with 10 treatments (T1-T10) The experiment's findings showed that a potassium concentration of 60 kg/ha combined with an NAA concentration of 100 ppm and a triacontanol concentration of 500 ppm led to the highest plant height (221.20 cm), dry weight (49.42 cm), and yield parameters for ear head length (20.50 cm), number of grains per ear head (1970), Test weight (9.38 g), grain yield (2.72 t/ha), and stover yield (3.78 t/ha).

Conclusion: Farmers found that using potassium at a rate of 60 kg/ha in conjunction with NAA at a concentration of 100 ppm and Triacontanol at a concentration of 500 ppm produced the best results, with plant dimensions of (221.20 cm) in height, (49.42 gm) in plant dry weight, (1972) grains per ear head, (9.38 g) test weight, (2.68 ta/ha) in grain yield, and (3.26 ta/ha) in stover yields, respectively.
