Productivity & Economics of Single Cross Hybrid Maize (Zea Mays L.) Under Varying Level of Hydrogel Polymer and Fertility Levels under Rain Fed Conditions

Abstract

            The experiment was conducted under field condition at Instructional Farm, RCA, MPUAT, Udaipur during rainy season of 2019 to ascertain suitable 4 hydrogel level (Control, 2.0, 5.0 and 7.5 kilogram per hactare) & 4 fertility levels (75 kilogram Nitrogen + 40 kilogram Poshporus +30 kilogram Potassium, 90 kilogram Nitrogen + 45 kilogram Phosphorus +35 kilogram Potassium, 105 kilogram Nitrogen + 50 kilogram Posphorus + 40 kilogram Potassium & 120 kilogram Nitrogen + 55 kilogram Posphorus + 45 kilogram Potassium per hactare). Results indicated that highest grain yield and economics was realized under application of 7.5 kilogram hydrogel polymer ha^-1, however in terms of Benefit Cost ratio 5.0 kg hydrogel polymer ha^-1 application proved economically beneficial and best to meet out water stress under rain fed conditions. Providing 105 kg N + 50 kg P₂O₅+40 kg K₂O ha^-1 affirmed potential role in increasing the productivity of single cross hybrid maize under rain fed conditions.
