Nodulation, yield and economics of summer Groundnut (Arachis hypogaea L.) as influenced by sulphur levels and plant growth regulators

Abstract

The experiment was conducted during the Zaid season of 2018 Prayagraj (U.P.).The experiment was conducted to study the Nodulation, yield and economics of summer Groundnut (Arachis hypogaea L.) as influenced by sulphur levels and plant growth regulators. The experiment comprised of 2 factors and 13 treatments viz. Sulphur (30, 40, 50 kg ha-1) and Plant growth regulators (NAA 50 ppm (at 20 DAS alone & at 20, 40 DAS), GA3 30 ppm (at 20 DAS alone & at 20, 40 DAS)) and control. Sulphur and Plant growth regulators application significantly influenced the nodulation, yield attributing characters and economics over control. Addition of sulphur at 40 kg ha-1 along with foliar application of 50 ppm NAA twice at 20 DAS and 40 DAS recorded highest Nodulation per plant (30 no.), Shelling out percentage (69.50%), Matured pods per plant (30.25 no.), Kernel yield (1.37 t ha-1), Gross returns (96,333.00 Rs ha-1), Net returns (53,935.00 Rs ha-1) and B:C ratio (1.27).
