Abstract

Under green-house conditions, an experiment was carried out at the Agricultural Research Centre, Giza on calcareous soil to evaluate the effect of Fe, Zn, Mn, Mo as well as their mixture applied by either seed coating or foliar application on pea yield and seed quality. The obtained results showed that straw and seed yields and 100-seed weight as well as seed content of total soluble sugars, total soluble amino acids, and crude protein were increased to different extents by micronutrients treatments. The mixture of these micronutrients induced the highest values. Seed coating exerts beneficial effects compared to foliar application. Seed coating with Mn and Mo gave the highest protein content, they also gave remarkable increases in the content of the total and individual amino acids of seed protein, comperced with. Fe or Zn and the mixture of the four elements except the amino acid proline which was found to be decreased by different micronutrients treatments. Moreover, seed coating with Mn and Mo recorded more increases than the foliar application of the same two elements. Fe, Zn and Mn content of pea straw and seeds were greatly increased by the application of these micronutrients either individually or in mixtures.
