Effect of Sulphur and Foliar Spray of Micronutrients on Growth and Yield of Zaid Groundnut (Arachis hypogaea L.)

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 And Sciences, Prayagraj, Uttar Pradesh, India. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.2), (EC 0.26 Ds/m), 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 Sulphur (20, 30, 40 kg/ha), Boron (0.2%) and Zinc (0.5%) along with control. Soil application of sulphur is done at the time of sowing, foliar application of boron and zinc was done at 25, 60 days after sowing. The experiment was layout in Randomized Block Design with ten treatments each replicated thrice. Significantly and higher plant height (57.42 cm), dry weight (30.93 g), and the yield attributes namely kernels/pod (2.27), pods/plant (43.33), kernel yield (2.58 t/ha), pod yield (2.54 t/ha) and haulm yield (6.29 t/ha), were obtained highest in the treatment 9 [40 Kg/ha Sulphur + 0.2 % Boron + 0.5 % Zinc].
