نفذت التجربة باستعمال الاصص خلال الموسم الشتوي للعام (2012 - 2013) م في تربة مزيجية وتحت الظروف البيئية الطبيعية في قسم علوم الحياة/ كلية التربية/ جامعة القادسية, لمعرفة تاثير مياه السقي الممغنطة والرش بتراكيز من البنزل ادنين ومستحضر السماد الطحلبي في ال | An experiment was conducted in the winter season of the year (2012 - 2013) in loam soil pots, in Biology department/ College of education/ Al - Qdisiya university, to find out effect of irrigation water magnetic, spryer of benzyl adenine concentrations and algal fertilizer on growth, mineral content and carotenoids to carrot plant (Daucus carota L.).The design of the experiment was randomized complete blocks (RCBD) in a factorial arrangement with three factors. The first factor was four intensities of magnetic to irrigation water (0, 500, 750 and 1000) gauss, the second factor was three concentration of benzyl adenine (0, 50 and 100) mg.L - 1 and third factor was three concentration of algal fertilizer (0, 1.5, and 3) ml.L - 1, with three replicates. The treatments means were compared by using averages revised least significant difference (RLSD) at 0.05 probability level.The following parameters were measured during the study plant height, leaf area, leaves number, vegetative fresh and dry weight, root dry weight, Leaves content of chlorophyll (a, b and total chlorophyll), carotenoids, Baicalin and Pycogenul, in addition to percentage of NPK, total protein and Fe (µg. g - 1). Results showed : 1 - The use of magnetic water by 1000 gauss were increase in plant height, leaf area, leaves number, vegetative fresh and dry weight, root dry weight, Leaves content of chlorophyll (a, b and total chlorophyll), carotenoids, Baicalin and Pycogenul, and magnetic water by 750 gauss were increase vegetative fresh weight and 500 gauss was increase K% but N%, P%, Fe (µg. g - 1) and protein% not affected by any different intensities to irrigated water.2 - Benzyl adenine at 100 mg. L - 1 concentration increased plant height, leaf area, leaves number, Leaves content of chlorophyll (a, b and total chlorophyll), carotenoids, Baicalin and Pycogenul, while 50 mg. L - 1 of benzyl adenine caused by increased in vegetative fresh and dry weight, N%, P%, Fe (µg. g - 1) and protein% but K% not affected.3 - The use of 3 ml.L - 1 algal fertilizer increased plant height, vegetative dry weight, P%, Fe (µg. g - 1), Leaves content of chlorophyll (a, b and total chlorophyll), carotenoids, Baicalin and Pycogenul. The concentration 1.5 ml.L - 1 algal fertilizer was increased leaves number but not affected in vegetative fresh weight, N%, P%, K% and protein%. The interactions with another factors caused increase of percentages. 4 - The interaction between magnetic water by 1000 gauss with 100 mg. L - 1 benzyl adenine increased plant height, leaf area, leaves number, leaves content of chlorophyll (a and total chlorophyll), carotenoids, Baicalin and Pycogenul. The use of magnetic water by same intensity (1000 gauss) with 50 mg. L - 1 BA increased vegetative dry weight, N%, P% and protein% while b chlorophyll was increase with 500 gauss and 100 mg. L - 1 BA.5 - the interaction between magnetic water and algal fertilizer concentrations revealed that use of 1000 gauss with 3 ml. L - 1 algal fertilizer increased plant height and leaf area, but the same interaction with 1.5 ml. L - 1 algal fertilizer increased leaves number, leaves content of chlorophyll (a and total chlorophyll), carotenoids, Baicalin and Pycogenul.6 - The interaction between benzyl adenine and algal fertilizer showed that used 100 mg.L - 1 BA with 3 ml. L - 1 algal fertilizer increased b chlorophyll, carotenoids and Baicalin, but use of the combination consisting of 100 ml. L - 1 BA with 1.5 ml/L algal fertilizer increased leaves number, leaves content of chlorophyll (a and total chlorophyll) and Pycogenul.7 - The triple interaction between experiment all factors revealed that increased in vegetative dry weight with two combinations (500 gauss magnetic water + 50 mg. L - 1 BA + 3 ml. L - 1 algal fertilizer and 1000 gauss magnetic water + 50 mg. L - 1 BA + 1.5 ml/L algal fertilizer). High P% was combination consisting of (500 gauss magnetic water + 100 mg.L - 1 BA + 1.5 ml.L - 1 algal fertilizer). High total chlorophyll, carotenoids, Baicalin and Pycogenul were combination consisting of (1000 gauss magnetic water + 100 mg. L - 1 BA + 1.5 ml. L - 1 algal fertilizer).
