Soil fertility status: As affected by micronutrient application in groundnut

Abstract

Groundnut (Arachis hypogaea L.) is important oilseed crop of Gujarat. It has good nutritional value in terms of 25 to 30% protein and 45 to 50% oil. Groundnut also known as king of oilseeds and various names viz., goober peas, pindas, jacknut, peanut and earthnut. The micronutrient have greater role growth stages and reproduction of plants i.e. iron, manganese, molybdenum, nicke, boron, chlorine, copper and zinc. An experiment was carried out during kharif season of years from 2020 to 2022 at Agricultural Research Station, S.D. Agricultural University, Aseda, Gujarat to find out the response of ferros sulphate and zinc sulphate on pod yield and soil fertility. Soil application and foliar spray of ferros sulphate and zinc sulphate were tested by for identifying their effect on soil fertility status after harvest of crop. Organic carbon, Available phosphorus and potash were non significantly influenced by the micronutrient application but higher value of both iron (5.044 mg/kg of soil) and zinc (0.489 mg kg-1 of soil) were found under the treatment T7 (FeSO4@ 15 kg ha-1 + ZnSO4 @ 8 kg ha-1) on pooled data basis of three years.
