Effect of Sulphur and Foliar Application of Iron on Yield and Economics of Lentil (Lens culinaris L.)

Abstract

A field experiment was conducted during Rabi 2022 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, (U.P) India to study the Effect of Sulphur and foliar application of Iron on Yield and Economics of Lentil. The experiment was laid out in Randomized Block Design comprising of two factors viz., Sulphur (20, 30, 40 kg/ha), Iron (control, 0.3%, 0.5%) and a Control (20-40-20 NPK kg/ha). There were 10 treatments each replicated thrice. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 6.9), Organic carbon (0.112%), available N (278.93 kg/ha), available P (10.8 kg/ha), and available K (206.4 kg/ha). Application of Sulphur and foliar application of Iron significantly influenced the yield and economics over control. Results revealed that yield attributes like more number of pods per plant (162.40), more number of seeds per pod (2.53), higher seed yield (1556.19 kg/ha) and higher stover yield (2868.3 kg/ha) were recorded with application of Sulphur 40 kg/ha + Iron 0.5%. Maximum gross returns (85590.45 INR/ha), net returns (57460.45 INR/ha) and benefit cost ratio (2.04) were also recorded in same treatment T9 (Sulphur 40 kg/ha + Iron 0.5%).
