Abstract
Abstract A field experiment was conducted on sandy soil at El‐Tahreer sector, El‐Behera Governorate, Egypt, to study the interaction between several micronutrients and their effect on the yield, elemental composition, and oil content of peanut. The micronutrients were manganese (Mn), zinc (Zn), and iron (Fe), which were added in their sulphate form at 20 kg/fed, with copper (Cu) also included being added at 10 kg/fed. The experiment included 16 treatments with six replicates arranged in a complete block randomized design. Nitrogen (N) and potassium (K) were added to the soil in two equal doses after three and six weeks from cultivation, while phosphorus (P) was added before cultivation as a basic dose. Results showed that all the added micronutrients led to an increase of the green plant (vegetative parts) and seed yield. The highest seed yield was associated with the combined treatment (Zn+Fe), while the highest yield for the vegetative part corresponds to the combined treatment (Fe+Zn+Cu). The plant concentrations and uptake of the micronutrients varied widely among the studied treatments. The highest concentrations for Fe, Mn, Zn, and Cu in seeds were associated with the combined treatments (Fe+Mn+Cu), Mn, (Fe+Zn+Cu), and (Mn+Cu), respectively, with some exceptions. The oil content in seeds increased slightly with the highest pil content at the combined treatment (Fe+Mn+Zn). The chemically extractable micronutrients in soil at the end of the experiment varied widely with treatments, and some antagonistic relationships between Fe and Mn and Zn and Cu were found.
