Response of nano urea and iron on yield attributes and economics of wheat (Triticum aestivum L.)

Abstract

The field experiment was on the Effect of Nano urea and Iron on growth and yield of wheat (Triticum aestivum L.) conducted at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) India and was performed during Rabi season of 2024. Experimental plot was sandy loamy soil of nearly neutral soil reaction (pH 7.2), low in organic carbon (0.48 percent), placed in the Randomized Block Design, repeated three times, with ten treatments i.e. T1: Nano urea 1.5 ml/l with Iron 0.25%, T2: Nano urea 2.5 ml/l with Iron 0.50%, T3: Nano urea 3.5 ml/l with Iron 0.75%, T4: Nano urea 1.5 ml/l with Iron 0.25%, T5: Nano urea 2.5 ml/l with Iron 0.50%, T6: Nano urea 3.5 ml/l with Iron 0.75%, T7: Nano urea 1.5 ml/l with Iron 0.25%, T8: Nano urea 2.5 ml/l with Iron 0.50%, T9: Nano urea 3.5 ml/l with Iron 0.75% and T10: Control (120:60:60NPK kg/ha). The maximum number of effective tillers /m2 (211.33), number of grains/spike (47.27), grain yield (4.28 t/ha), straw yield (6.54 t/ha). The economics of experiment, i.e., maximum gross return (107240.00 INR/ha), net return (72710.60 INR/ha) and B:C ratio (2.11) was also recorded in T9: Nano urea 3.5 ml/l with Iron 0.75%.
