Effect of Soil and Foliar Application of Micronutrients on Yield parameters of Groundnut (K-6) (Arachis hypogaea L.) in Red Sandy loamy Soils

Abstract— A field experiment entitled ―Effect of Soil and Foliar application of micronutrients on Yield parameters of Groundnut (Arachis hypogaea L.) (K-6) in Red Sandy Loamy Soils was conducted during rabi’2024. The experiment was laid out in Randomized Block Design (RBD) and replicated thrice with ten treatments. The treatments consisted of T1(Control), T2(RDF + FYM@ 10 t ha-1), T3 (RDF+ soil application of ZnSO4@ 16 kg ha-1 as a basal), T4(RDF + soil application of FeSO4@ 10 kg ha-1 as a basal), T5(RDF + soil application of borax @ 10 kg ha-1asabasal),T6 (RDF + soil application of ZnSO4@ 16kgha-1 + FeSO4@ 10kgha-1+ borax @ 10 kg ha-1 as a basal),T7FoliarApplication [email protected] % at 30DAS and 60 DAS, T8 Foliar application [email protected]% at30and 60 DAS, T9 Foliar application of borax @0.25 % at 30and 60 DAS,T10Foliar application of ZnSO4 @ 0.2 % + FeSO4 @ 0.5 % + borax @0.25% at 30 and 60 DAS. The results indicated that application of each and combined micronutrients through soil methods significantly influenced the Yield parameters and quality parameters of groundnut crop. The yield Parameters and yield viz. number of pods plant-1(12.93), pod yield (2506 kg ha-1) and haulm yield (3339 kg ha-1) of groundnut were recorded with application of RDF + FYM @10 t ha-1 and found significant over control (T1). From the findings it can be concluded that Application of FYM and combined soil application of all micronutrients followed by individual micronutrient application alone found better than foliar application of each micronutrient alone. The highest Yield parameters were obtained with the combined soil application of all micronutrients.
