| Abstract | ||
| A field experiment was carried out at the Department of Horticulture and land scape gardening , College of Agriculture , University of Baghdad , Abu Ghraib, in the season 2008 - 2009 to study the effect of different concentrations of manganese (0,30.60 mg. Liter- 1 ) and borone concentrations (0,250, 500 mg. Liter- 1) in the growth and productivity of seeds of onion plant (Allium cepa L) variety Texas Early Grano experiment applied in Factorial experiments (3X3X3) within RCBD in three replications , plants sprayed with manganese and boron four times ( spray at 1/12/2008 and repeat spraying each 30 days. Statistical analysis results showed significant superiority of treatment Mn2 (60 mg . L -1) to give a higher number of flowers in umbel ( 787 flower ) and higher percentage of flower setting (69.7%) compared to the least values that were found at the treatment of Mn0, It also B1 (250 mg . L -1) treatment characterized by giving the highest values of the yield of umbel (6.08 g) and total production (609 kg. H -1) as well as the germination percentage (91.11%) compared to the lowest values when treatment B0 , effect of interaction has characterized in the treatment of Mn2B1 which gave highest values the number of seeds in flowers 3658 seed ), yield of umbel (6.75 g ) and total yield (675 kg. H. - 1), while the lowest values found in treatment Mn0B0. | ||
