Influence of Hydrogel and Different Sowing Methods on Growth and Yield Aerobic Rice (Oryza sativa L.)

Abstract

The field experiment was conducted during Khairf 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P).To evaluatedo the influence of different level Hydrogel (0, 2, 4 kg/ha.) and methods of sowing( on growth and yield of aerobic rice. Hydrogel was broadcasting in the field before sowing (Flatbed sowing. Ridge sowing, furrow sowing) mixed well in the soil. The experiment was laid out in randomized block design and comprised of levels of hydrogel and methods of sowing with ten treatments and each were replicated thrice. The growth attributes which was plant height (96.20 cm), total tillers/m2 (540.27), plant dry weight  (1078.70 g/m2), and crop growth rate (65.27 g/m2/day) was significantly increased with increasing the level of Hydrogel (0, 2 to 4 kg/ha.) and maximum was obtained with application of 4 kg Hydrogel with Furrow sowing. The yield attributes was obtained highest effective tillers/m2 (238.33), number of filled grains/panicle (172.83), grain yield (4.81 t/ha), Harvest index (44.35%), gross return (INR 1,76,043/ha), net return (INR 1,31,193/ha.) and benefit cost ratio (2.93).
