Abstract

The field experiment was conducted during Zaid season 2022 at experimental field of Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj and 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 Zinc soil application (2.5,5 kg/ha) and Zinc foliar application (0.3, 0.6%) along Boron (0.3%) and Iron (0.3%) along with control. The experiment was layout in Randomized Block Design with ten treatments each replicated thrice. Higher plant height (185.19cm), maximum plant dry weight (92.86 g) and the yield attributes namely test weight (15.50g), grains/earhead (1297.67), grain yield (3.03t/ha), stover yield (4.16t/ha) was with treatment 9 [Zinc 2.5ka/ha + Zinc 0.3% + B 0.3% + Fe 0.3%].

Keywords: Sorghum, iron, boron, zinc, growth, yield
