Abstract
Under ~eld conditions. pea plants cv. Masler B were cultivated in a clay loamy soil receiving sulphur at 0 or 50 kg 1 fed. and sprayed with Fe at 100ppm. Zn at 50ppm and Mn at 50pmm or a mixture of Fe, Zn and Mn at the previous concentrations as chela led forms. The foliar spray was repeated Four times at 10 days intervals starting 45 days after planting. The experiments were carried out during the two successive winter seasons of 1998/1999 and 199912000.
,. Sulpur application to the soil significantly increased plant 9rowth parameters (Plant height, no- branches and no-leaves per plant) and contents of Fe, Zn and Mn in lear lissuss. The treatment had merits on reduction of aborted ovules Ipod and increased pod weight, no-pods/ plant, lotal green pods yield, seed index, dry seed yield and protein content in dry seeds,
2- Foliar application with a mixture of Fe, Zn and Mn or Zn alone to pea plants resulted inSignificant increase in plant growth characteristics. Contents of Fe. Zn and Mn in leaves followed the same pallens of changes as that mentioned before. Fresh pod yield and its components were increased. Additionally, seed index. dry seed yield and protein content in dry seed were also significantry greater than control.
3- The interaction of sulphure and mixture of Fe, Zn and Mn or Zn alone had signifICant increase in some plant growth charcters I]S well as pod fresh yield and Its components. Similar results were found for dry seed yield, seed index and protein content of these seeds.
The results Indicate that sulphure supplement to the clay loamy soil can be used successfully for peas production in combination with foliar spray of micronutrients.
