The impact of growing media and treatment of magnesium sulfate in the growth of aquatic plants and flowers Jaafari (Tagetes erecta

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.
