Effect of Organic Manures and Nano Zinc on Growth and Yield of Wheat

Abstract

A field experiment was carried out 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 (pH7.3), 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 treatments consist of organic manures (FYM 10t/ha, panchagavya 3%, FYM 5t/ha + panchagavya 1.5%) and nano zinc (30, 40, 50 ppm) along with control plot (Recommended Dose Fertilizer). The experiment was layout in Randomized Block Design (RBD) with ten treatments each replicated thrice. Higher plant height (91.90 cm), higher plant dry weight (27.27 g), number of tillers/hill (8.67), Crop Growth Rate (11.82), grains/spike (45.12), effective tillers/row meter (73.57), Spikes/running row meter (77.57), grain yield (6.01 t/ha), straw yield (8.49 t/ha), maximum gross return (127712.50 INR/ha), net return (85765.70 INR/ha) and B:C ratio (2.04) were also obtained highest in the treatment 9 [FYM 5t/ha + Panchagavya 1.5% + Nano-zinc 50ppm].
