Abstract
Abstract Broadcasting Fe increased alfalfa forage yield in calcareous soils, however, higher yield was obtained by using broadcasting and foliar application together. In sandy soil, broadcasting 24 kg Ferrous sulphate Ha‐1 significantly decreased the yield while 12 kg Ferrous sulphate + 12 kg Borax Ha‐1 produced the highest yield. The highest uptake of Fe by the alfalfa in calcareous soil was by the foliar application followed by combination of both methods. Broadcasting produced the lowest uptake. Foliar application of B in sandy soil was superior to broadcasting, while broadcasting Borax produced the highest yield in calcareous soil. Soil + foliar application of Fe to calcerous soil increased CP% in herbage. Soil and/or foliar application of B or B + Fe had similar effect. Soil application of Fe to calcareous and sandy soils increased the hemicellulose percent. Boron soil application to calcareous soil and foliar application of B + Fe to both soils increased ADF and decreased hemicellulose percent of the forage.
