effect of spraying with active yeast and iron on vegetative and flowering growth of plant Calendula officinalis L.

Abstract

An experiment was conducted in the lath house as the College of Agriculture Kerbala university during the growing season 2012 - 2013 to study the effect of spray with active yeast and iron on vegetative and flowering growth of Calendula officinalis plantThis experiment was carried out using design random Completely Randomized Design experiment based on factors by two factors commentator yeast and three concentrations are ( 4, 2, 0g / l ) and iron Grapple three concentrations are (200- , 100.0 mg / L) and three replicates each, sprayed seedlings three workshops during the growing season spray the first was after a month of the transfer of the seedlings to their place of permanent and was the period of time between the workshop and the other 10 days , and in the end of the research took data were analyzed results by design, the user has the comparison between the averages by testing less significant difference and at the level of 71- outperformed treatment with active yeast concentration of 4 g / l on the rest of concentrations in all traits ( plant height , leaf number overall , leaf area , the content of the leaves of chlorophyll , fresh weight of shoots , dry weight of shoot , number of flowers, flower diameter ) which gave the highest rates , which amounted to ( 29.33 cm, 40.33 paper / plant , 1185.63 cm 2, 65.12 SPAD, 19.23 g , 2.94 g , 18.89 flower / plant , 4.88 cm).2- achieved a concentration ( 200 mg / L) of iron grapple significant superiority over the rest of the concentrations in all the qualities of the ( number of leaves total , leaf area , the content of the leaves of chlorophyll , fresh weight of shoots , dry weight of shoot , number of flowers, flower diameter ) . This has given the highest rates of ( 41.22 paper / plant , 1088.40 cm 2, 61.57 SPAD, 19.22 gm , 2.72 gm 18.67 flower / plant , 4.88 cm ), respectively .3- As for the overlap between the spraying with active yeast and iron grapple has had a significant effect in the recipe ( plant height , leaf number overall , leaf area , the content of the leaves of chlorophyll , fresh weight of shoots , dry weight of shoot , number of flowers , flower diameter ) . Which gave the highest total ( 33.41 cm, 43.44 paper / plant , 1327.50 cm 2, 67.43 SPAD, 21.73 g , 3.11 g , 20.08 flower / plant , 5.23 cm) , respectively, at a concentration of 4 g / l of yeast and 200 mg / L of iron .
