Abstract

Purpose: is to enhance the nutrients use efficiency (NUE) along with the crop yield and quality by magnetic treatment (MT) of the groundnut (Arachis hypogaea L.) seeds pre-sowing as well as the MT of water used to dissolve the nitrogen (N) fertilizer under sandy soil field conditions. Methods: Treatments were distributed in a split-plots design in triplicates. The control CL has received the recommended dose RD of the N-fertilizer while other treatments received a 50% of the RD applied to the surface soil 30 days after planting. The main factor (F1) was the N-application rates 1000, 2000, and 3000 mg kg-1 of urea dissolved in the magnetically treated water (MTW) then sprayed on the soil in the liquid form five times after planting. The sub-factor (F2) was the time of MT (15, 30, and 45 min) of the groundnut seeds exposed to a magnetic field MF 1.4 T intensity before planting. Results: The soil available N, P, K, Fe, Mn, and Zn (mg kg-1) were increased significantly by 34.8%, 23.0%, 3.49%, 9.4%, 22.2%, and 23.2% respectively, at P ≤ 0.05 by the 45 min MT and 3000 mg kg-1 N relative to its corresponding control (CL). The MT has increased the seeds yield (kg ha-1) significantly in the order 45 min >30 min >15 min for the N-rates 1000, 2000, and 3000 mg kg-1. At the 45-min time, it was increased by 17.5, 15.3, and 14.8% for the N-rates, respectively. Conclusions: The 2000 mg kg-1 rate with MT of seeds for 15 min can be recommended for an acceptable nutrients use efficiency (NUE).
