ABSTRACT
The field experiment was conducted during rabi 2022 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj (U.P.) India. To study the Response of Organic manures and potassium on growth and yield of Pearl millet The treatment combinations were T1: FYM 5t/ha + 30 kg/ha potassium, T2: FYM 5t/ha + 40 kg/ha potassium, T3: FYM 5t/ha + 50 kg/ha potassium, T4: Vermicompost 5t/ha + 30 kg/ha potassium, T5: Vermicompost 5t/ha + 40kg/ha potassium, T6: Vermicompost 5t/ha + 50kg/ha potassium, T7: Poultry Manure 4t/ha + 30kg/ha potassium, T8: Poultry Manure 4t/ha + 40kg/ha potassium, T9: Poultry Manure 4t/ha + 50kg/ha potassium, and control plot T10:(RDF80:40:40 NPK kg/ha) . Results obtained that the plant height (168.06 cm), plant dry weight(48.87 g/plant),crop growth rate (24.0 g/m2/day), ear head length (25.07cm) number of grains/ear head (2372.69), test weight (10.92 gm), seed yield (36.90 q/ha) and stover yield (68.03 q/ha)were significantly influenced with application of Poultry Manure 4t/ha + 50 kg/ha potassium. Higher gross return (INR 86707.17/ha), higher net return (INR 58590.17/ha) and highest B:C ratio (2.08) were also recorded in treatment-9 (Poultry Manure 4t/ha + 50 kg/ha potassium).
