Influence of Nano Potassium and Nano Zinc on Yield and Economic Enhancement on Wheat (Triticum aestivum L.)

The present field experiment was conducted during Rabi season 2022 at experimental field of Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj, Uttar Pradesh, India. In experimental plot, soil was sandy loam in texture, nearly neutral in soil reaction (pH 7.3), low in organic carbon (0.48%), available nitrogen (230 kg/ha), available phosphorus (13.60 kg/ha) and available potassium (215.4 kg/ha). The treatment consists of 3 levels of Nano-potassium 25, 40, 55 ppm and Nano-zinc 60, 80, 120 ppm along with control. The experiment was designed using Randomized Block Design, with ten treatments reproduced three times. Yield attributes namely spike length (11.93 cm), grains/spike (51.67), spikes/running row meter (62.90), effective tillers/running row meter (60.10), grain yield (6.61 t/ha), straw yield (8.90 t/ha), maximum gross return (140462.50 INR/ha), net return (99555.93 INR/ha) and B C ratio (2.43) were obtained highest in the treatment 9 [Nano-potassium 55ppm + Nano-zinc 120ppm].
