Response Of Mango (Mangifera Indica L.) And Lime (Citrus Aurantifolia L.) To Magnetized Irrigation Water

Abstract

Two experiments were carried out at Alsha\\\\\\\'ab Agricultural Project (Al Faki Hashim Khartoum-North) and in the Date Palm Technology Co. Shambat, from June 2005 to April 2006. The purpose of the experiments was to study the effect of water charged by the magnetic technology on growth and production of fruit plants. Complete randomized experiments were designed for two varieties of mango (Mangifera indica L.) Tommy Atkins and Kitchener and one variety of lime (Citrus aurantifolia L.). The treatments consisted of magnetized water and non-magnetized water and each treatment was replicated five times. The plant growth attributes considered were: plant height, number of main branches, stem diameter, branch length, number of leaves per branch, leaf length and width, number of sub-branches per branch and number of fruits per plant. When magnetized water was used for Tommy Atkins, the results of the study showed a significant difference (P =603; 0.05) in the increase of plant height (26.21%), number of leaves per branch (282%) and number of fruits per plant (21) as compared to non magnetized water, which gave 12.15% increase in plant height, 74% increase in number of leaves per branch and 15 fruits per plant. A highly significant difference (P =603; 0.01) was obtained in the increase of stem diameter (45.73%), branch length (45.4%), leaf length (16%) and leaf width (32.85%) when magnetized water was used as compared to average values of (22.53%), (18.32%), (5.6%) and (7.63%) increase in the same parameters respectively when non magnetized water was used. However, there was no significant difference (P =603; 0.05) in number of main branches (21.75%) and number of sub-branches per branch (5.4%) when magnetized water was used as compared to non magnetized water, which gave 18.44 increase in number of main branches and 4.4% increase in number of sub branches per branch. On the other hand, when magnetized water was used for nursing Kitchener mango a highly significant difference (P =603; 0.01) was obtained in the increase of plant height (24.19%), stem diameter (54%) and leaf width (18%) as compared to their respective values of (11.52%), (25.25%) and (7.55%) when non magnetized water was used. Whilst the difference was significant (P =603; 0.05) when magnetized water was used giving (50.75%) increase in number of leaves per plant and (21.5%) increase in leaf length as compared to values of (28.25%) and (6.5%) respectively when non magnetized water was used. The results also showed that there were highly significant differences (P =603; 0.01) when magnetized water was used for lime trees giving (43.08%) increase in stem diameter and (30.73%) increase in leaf width as compared to respective values of (24.8%) and (11.32%) when non magnetized water was used. Whilst there were significant differences (P =603; 0.05) in the number of leaves per branch (889%), increase in leaf length (22.88%) and sub-branches/branch (21.6) as compared to respective values of (416%), (9.91%) and (9.2) when non magnetized water was used. The results also showed that there were no significant differences (P =603; 0.05) in the increase of plant height (20.69%) and number of main branches (13.83%) as compared to respective values of (18.73%) and (11.95%) when non magnetized water was used. Hence, it was concluded that magnetizing water may lead to increase in stem diameter and leaf area, which would lead to better crop production.
