Abstract: The field experiment was conducted at the Crop Research Farm, SHUATS, Prayagraj (U.P.), during the month of Zaid season (2023). To determine the “Effect of Plant growth regulators and Zinc on yield and Economics of Pearl millet (Pennisetum glaucum L.)”. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.8), low in organic carbon (0.62%), available nitrogen, available phosphorus and available potassium. The treatments combinations are T1: NAA 100 ppm + Zinc 15 kg/ha, T2: Choloromequat – 250 ppm + Zinc 15 kg/ha, T3: NAA – 50 ppm + Choloromequat – 175 ppm + Zinc 15 kg/ha, T4: NAA 100 ppm + Zinc 20 kg/ha, T5: Choloromequat – 250 ppm + Zinc 20 kg/ha, T6: NAA- 50 ppm + Choloromequat – 175 ppm + Zinc 20 kg/ha, T7: NAA 100 ppm + Zinc 25 kg/ha, T9: Choloromequat – 250 ppm + Zinc 25 kg/ha, T9: NAA -50 ppm + Choloromequat – 175 ppm + Zinc 25 kg/ha, T10: Control 80:40:40 (NPK kg/ha) are used. Results obtained that combined application of NAA-50 ppm + Choloromequat – 175 ppm + Zinc 25 kg/ha (Treatment 9) significantly increased higher Ear head length (14.86 cm), Grains /ear head (1479.64), Test weight (5.30), Grain yield (23.29 q/ha), straw yield (42.89 q/ha) and Harvest index (35.19%). And also the treatment recorded maximum gross return (1,16,450.00 INR/ha), net return (81,650.00 INR/ha) and B:C ratio (2.34).
