Effect of Nano Potassium and Nano Zinc on Growth and Yield Enhancement in Wheat (Triticum aestivum L.)

The 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. The soil of experimental plot 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 layout in Randomized Block Design with ten treatments each replicated thrice. Higher plant height (93.43 cm), plant dry weight (26.99 g), tillers/running row meter (73.57) and the 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) and straw yield (8.90 t/ha were obtained highest in the treatment 9 [Nano potassium 55ppm + Nano zinc 120ppm].
