Abstract:
ا جريت هذه التجربة في قسم علوم الحياة / كلية العلوم / جامعة الكوفة في محافظة النجف الاشرف وتضمنت مرحلتين : الاولى زراعة البذور لغرض قياس نسبة الانبات للمدة من 1 / 8 لغاية 8 / 8 / 2011 وانتاج الشتلات للمدة من 15/8/2011 ولغاية 14 / 9 /2011 في حقل خاص لانتا | This experiment was conducted in the Department of Biology, College of Sciences, University of Kufa in Al - Najaf Al - Ashraf province. It included two periods : the first was seed sowing to measure germination percentage from 1 - 8 till 8 - 8 - 2011, and transplants production from 15 - 8 - 2011 till 14 - 9 - 2011 in a private farm for vegetable transplants production. The second was transplanting in an open field belongs to Plant Production Department/Kufa Technical Institute from 15 - 9 - 2011 till 17 - 1 - 2012 to measure plant growth parameters and curd cauliflower production cv.solid snow in harmless environment techniques. The experiment was adopted as factional experiment. The treatments were distributed according to Randomized Complete Block Design (RCBD) with four replicates. The experiment included the study of two factors : the first, was five magnetic intensities for treating waters magnetically (0; 500; 750; 1500 and 2500 Gauss) by means of dipolar magnetrons. The second was three quantities of plant organic manure(rice residues).i.e.(0, 2.5 and 5.0 kg/furrow) with a length of 6.5 m. and their interactions on growth and production the yield of cauliflower, cv.solid snow. Duncan's Multiple Range Test (DMRT) was used to compare means at probability of0.05. Correlation and regression coefficient were also used to evaluate the relationships between studied parameters and time. Vegetative growth parameters that are measured were : plant leaf number ; stem height; stem diameter; plant leaf area; leaf fresh and dry weight; stem dry weight; plant shoot fresh and dry weight. Flowering parameters were : curd fresh and dry weight and curd diameter. The results could be summarized as following : 1. Water chemical analysis showed that irrigation with magnetized treated water had an effect on physical properties, nevertheless, was more or less affected ions components. 2. The use of magnetized treated water in irrigation resulted in an increase in germination percentage of cauliflower seeds cv. Solid snow.The highest germination percentage was obtained from magnetic intensity of 1500 Gauss in both experiments, laboratory and field that reached 71.14 and 65, 62%, respectively on the base of Arc Sin. 3. The use of magnetized treated water in plant irrigation at all the used intensities resulted in an early emerged curd cauliflower by 15 days compared with control treatment plants. 4. 750 gauss magnetized treated water achieved at age of 138 days from transplanting, the highest plant leaf area mean is (4836.2 cm2) with percentage increase of 51.7% compared to control treatment plant leaf area (3188.3 cm2).That effect was reflected on curd weight. 5. 1500 and 2500 Gauss magnetized treated water treatments at earlier ages increased the values of vegetative growth parameters which reflected its effect on flowering growth parameters by shorter time of curd irritation, compared with the effect of 500 - 750 Gauss at earlier ages , which are in spite of its late effects produced at 150 days old from transplanting particularly 750 Gauss the highest mean of curd fresh weight. 6. 750 Gauss magnetized treated water achieved the highest yield reached 22.2 ton/h. which differed from that productivity gained from control treatment plant(9 - 29 ton/h.) with percentage increase of 138.8%. 7. Organic plant manure addition at both quantities(2.5 and 5.0kg/furrow) resulted in an increase in both vegetative and flowering growth parameters compared with untreated plants. 5 kg/furrow treatment produced the highest means compared to control treatment particularly at the age of 138 days in all vegetative growth parameters. 8. The addition of 5 kg/furrow at age of 150 days produced the largest curd fresh weight 918.4 g. and diameter of 17.2 cm which statistically differed to compared plant treatment that produced 506.0 g. and 13.3 cm. for curd fresh weight and diameter at the same age respectively. 9. 5 kg/furrow organic manure addition resulted in a highest productivity of 21.6 ton/h. compared to that of control treatment of 11.9 ton/h. with an increase of 81.5%. 10. Interaction between irrigation water magnetically treated with 750 Gauss and addition of (organic manure with 5 kg/furrow) at the age of150 days resulted in the highest curd fresh weight of 1292.9 g. with curd diameter of 20.3 cm. compared to that plant of control treatment produced curd fresh weight of 292.5 g. and 11.0 cm. diameter. This interaction also produced 30.3 ton/h. for (750 Gauss×5 kg/furrow) compared with the productivity of control treatment plants that gave 6.86 ton/h. with percentage increase of 341.6%
