Abstract:
A field experiment entitled “foliar application of urea and micronutrients on growth, yield attributes and yields of groundnut in loamy sand” was conducted at Agronomy Instructional Farm, C. P. College of Agriculture, S.D. Agricultural University, Sardarkrushinagar, Gujarat during summer season of 2019-20. Total eight treatments viz., Control/RDF (T₁), T₁ + 1.5% Urea spray at 35 DAS (T₂), T₁ + 1.5% Urea spray at 50 DAS (T₃), T₁ + 1.5% Urea spray at 35 DAS and 50 DAS (T₄), T₁ + 0.5% FeSO₄ and ZnSO₄ at 35 DAS (T₅), T₁ + 0.5% FeSO₄ and ZnSO₄ at 35 DAS and 50 DAS (T₆), T₁ + 1.5% Urea spray + 0.5% FeSO₄ and ZnSO₄ at 35 DAS (T₇), T₁ + 1.5% Urea spray + 0.5% FeSO₄ and ZnSO₄ at 35 DAS and 50 DAS (T₈) were laid out in randomized block design with four replications. The results reveal that application of RDF + 1.5% Urea spray + 0.5% FeSO₄ and ZnSO₄ at 35 DAS and 50 DAS significantly increased the no. of pods/ plant, pod yield/ plant (g), pod yield (kg ha^-1) and haulm yield (kg ha^-1). Available nitrogen, P₂O₅, K₂O, DTPA extractable Fe & Zn content in soil after harvest of crop did not differ significantly due to by foliar application of urea and micronutrients.
