Abstract

Carried out research in one of the private nurseries in Muthanna province during the spring season in 2012 to study the effect of three circles of agricultural ( soil only 0.1 soil : 1 Batamos and 2 soil : 1 Batamos ) Size : The size , in pots , plastic , and irrigation with three concentrations of magnesium sulfate water ( 0 , 1.5, 3) g . L -1 and overlap between the two indices vegetative growth and syphilis plant Jaafari , do research experiment factorial Factorial experiment (3 × 3) two factors designed randomized complete block (RCBD) Randomized Complete Block Design with three replicates , and compared to the averages , according to test less significant difference LSD and at the level of probability 0.05 .      The results showed that the growth of agriculture in the center (1 soil : 1 Pettmos ) or magnesium sulphate irrigation water had a significant effect on vegetative growth indicators and syphilis measured in the plant.     The overlap between the workers experience had a significant effect on growth indicators , as it gave the treatment plant cultivation in growth medium (1 soil : 1 Batamos ) and a concentration of 3 g treatment . -1 Liter of magnesium sulfate highest rate of plant height , stem diameter main , number of leaves college, dry weight of shoots , flower diameter , number of flowers . Plant -1, dry weight of the flower , the content of the leaves of the chlorophyll content of the leaves of carbohydrates total dissolved , which amounted to ( 95.2 cm, 10.5 mm , 53.10 paper . Plant -1 and 7.46 g , 7.62 cm, 8.87 Flower . Plant -1 , 0.542 g; 16.45 mg . g weight mushy -1 and 23.92 mg . g dry weight -1) and , respectively , while given treatment comparison ( agriculture in the center of the growth of soil only and not watering sulphate , magnesium ), the lowest rate for this indicator amounted to ( 60.3 cm, 6.51 mm , 24.21 paper . plant -1 and 5.17 g , 5.41 cm, 5.21 flower . plant -1, 0.421 g , 10.11 mg . g weight mushy -1 and 20.71 mg . g dry weight -1) , respectively.
