| Abstract | ||
| This study was carried out during fall season of ( 2012-2013) at experimental field , Horticulture Department , College of Agriculture – University of Diyala, to study the moisture depletion concentrations of Potassium and Boron applied on foliar on Plant height ,leaf area, grain yield, proline and protein contend of faba bean (Vicia faba, L.) cultivar (Babylon). The layout of the experiments was Split- split plot design as RCBD with three replicates. Three concentration of Potassium 4500 ,5000 ,5500mgK.L-1added as K2SO4 (41%K)and three concentrations of Boron 0 , 300 , 350 mgB.L-1 used Boric acid (17.4%B) and three periods of irrigation after25,50,75% depletion of available water . Foliar application were applied at three times during of plant growth. Results drawn from this experiment are summarized as follows: The differ significantly in all of characters with increasing Potassium concentrations . Plant height ,leaf area and grain yield increased with the second level of Boron concentration (5000) mgB.L-1.. The differ were significantly between Potassium levels and water stress levels in most of characters. Plant height ,leaf area and grain yield increased with the interaction between water stress levels x the second Boron levels . Also the most of characters were significantly influenced by interaction between moisture levels x Potassium and boron concentrations . Boron did not effect the proline and protein content , proline and protein increase with water stress. | ||
