The Influence of Foliar Application of Manganse and Boron on som Quantity and Quality Characteristic for maize (Zea mays L.) Under water stress conditions

journal of kerbala university, Volume 13, Issue 1, Pages 233-242

This experiment was conducted in private field at Al- Mussiab reigion during spring season 2014, to study the effect of water stress by using foliar application concentrations of boron and Manganese on some Quantity and Quality characters for (Zea mays L.) grain yield, bioloyical yield, chlorophyll content, proline and Absisic acid (ABA) content of maize cultivar 5012.
Spilt plot design arrangement within (RCBD) with three replicates were used three concentration of spraying Manganese (0, 20, 40) mg Mn. L-1. as Mn-EDTA (13%Mn) and three concentrations of spraying Boron (0, 3, 6) mg B. L-1 as Boric acid (17%B were used as ofliar fertilizer at three levels (25, 50, 75)% of available water. Foliar fertilizer were applied at three times during at (40, 60, 80) day after planting. The resuts of these experiments were sumarized as follows :
Grain yield, biological yield and chlorophyll content increased with the increase in Manganese and Boron consentrations. The varieties differ significantly between Manganese levels and water stress levels in most characters. Chlorophyll content increased with the interaction between water stress level x Boron levels. Also the most of characters were significantly influenced by interaction between moisture level x Manganese and Boron concentrations. The two nutrient (Mn and B) do not effect in ABA content, ABA increase with water stress.
