Rp_Using of factorial experiment design to study the effect of interaction between magnetized water and Nano particles in one growth indicators pdf

The aim of this thesis is to study the effect of the interaction between magnetized water and Nano nutrient compounds on the vegetative system length (hypocotyl length) for pepper plant seeds.
This study investigated the effect of two factors (magnetized water (distilled water, river water) and Nano nutrients of the copper element (CuO) on the vegetative system length (hypocotyl length) for pepper plant seeds.
The importance of the research is that when conducting agricultural experiments according to plans and scientific foundations and their adoption of the subjects of design and analysis of experiments is of great importance because these agricultural experiments lead to the development of the agricultural sector and indicate the optimal ratios of treatments that affect significantly variable response and consider them as future plans to be relied upon later.
The experiments were conducted in the plant research laboratories of the Department of Biology Sciences / Faculty of Sciences / University of Babylon and the experiment took a period of time from 2018/7/12 until 2018/8/10.
The factorial experiment was applied according to the randomized completed blocks design (3 × 3 × 4) with three blocks. The Nano nutrients materials of CuO were used in four concentrates (1,3,5,7) molar, and the water was magnetized by (1000,2000,3000) G.
The factorial experiment was analysed according to the randomized completed blocks design. There was no significant difference in the vegetative system length among the blocks of the treatments used in the experiment. Therefore, the data on the experiment have been re-analysed according to the randomized completed design.
Also, The analysis of variance was conducted when control data were present and, if not present, to determine the effect of each factor on the hypocotyl length of the pepper plant and also the effect of the interaction on the hypocotyl length of the pepper plant. The results showed that there was a significant effect of the interaction of Cu Nano materials (CuO) at (3M) and the distillate distilled water at the third level (3000G). There was also a significant effect of the two factors Nano-CuO at second level (2M) and magnetized river water at second level (2000G).
The results showed significant differences among the responses means for the interaction of magnetized water levels and the Nano-copper. The second level of magnetized river water (2000 G) and the second level of the Nano element (3M) gave the highest rate of vegetation length (hypocotyl length) (10.83mm) for one seed. While the interaction of the second level of river water (2000G) with the first level of the nanoparticle (1M) gave the same rate of vegetation length (hypocotyl length) as the interaction of the third level of river water (3000G) with the second level of nanoparticle (3M) ,which was (9.33mm) for one seed.
The interaction of the first level of distilled water (1000G) with the second level of (3M) gave the same rate of vegetation length (hypocotyl length) as the interaction of the second level of distilled water (2000G) with the second level of nanoparticle (3M) ,which was (9.17mm) for one seed.
The linear and quadratic compound of the magnetization intensity in the status of distilled water, behaved in the same manner as the river water, while the linear and quadratic compounds of the nano nutrient behaved differently depending on the quality of the magnetized water , which means that the nano nutrient is affected by the quality of magnetized water, while the intensity of magnetization is not affected by water quality according to the limits of this study.
The treatment (b2) was superior to the other magnetic tensile levels at an average of 9 mm. This enables us to estimate the ultimate end of the magnetic tensile effect.
Moreover, the interaction of the influence of compounds of the two factors in their impact on response has varied, which supports the fact that the river water is not under control as it is in distilled water.
