Background: Pearl millet can thrive in a wide range of local conditions. In areas where sorghum cannot thrive, pearl millet is a viable alternative. Sorghum and maize can't compete with pearl millet when it comes to soil moisture utilisation and heat tolerance. Objectives: Effects of Potassium and plant growth regulators on yield and economics of pearl millet. Methods: With the goal of studying the effect of Potassium and plant growth regulators on yield and economics of Pearl millet (Pennisetum glaucum L.) Var. NBH - 5658 under a Randomized block design with 10 treatments (T1-T10 The experimental results revealed that Potassium 60 kg/ha + NAA-100ppm,+Traicontonol-500ppm, produced ear head length (20.50 cm), Number of grains/ear head (1970.0), grain yield (2.72 t/ha), Stover yield (3.78 t/ha) harvest index (41.84 %).T9 Potassium 60 kg/ha + NAA-100ppm,+Traicontonol-500ppm produced greater gross returns (1,36,000.00 INR/ha), net returns (92,840.00 INR/ha), , and benefit-to-cost ratios (2.14).
