Effect of treatment by nutrient solution (SiliKaSol) and irrigation with magnetically treated water on some physical and chemical properties of tissue-grown short-stem banana plants in greenhouse conditions

This study was conducted at the Agricultural Research and Experiment Station, College of Agriculture, Basra University, from 02.01.2018 to 30.06.2018 on the Indian short-stemmed banana plant M.caredishii, multiplied by tissue in the tissue culture laboratory of the Palm and Localized Research Center, at 6 months age. They were grown in a greenhouse equipped with a desert cooling system. The plants were sprayed with 5 concentrations of the nutrient solution SiliKaSol (0, 0.5, 1, 1.5, 2) ml l-1 and by 5 sprays between one spray and another 10 days starting from 02.01.2018. These plants were irrigated during the study period by two types of irrigation water: magnetically treated water and normal water. The most important results can be summarized as follows:- Spraying at a concentration of 2 ml l -1 of the nutrient solution showed a significant increase in the physical characteristics (increase in plant height and leaf area), reaching 32.33 cm and 312.83 cm2 , respectively, and an increase in chemical properties (content of leaves from proline, total soluble carbohydrates, total chlorophyll and nitrogen percentage in the leaves) reached 16.01 µg g-1 , 1.26 mg g-1 and 4.31 mg g-1 , respectively. The results also showed that the quality of irrigation water had a positive effect on improving most of the physical and chemical properties, as watering with magnetized water achieved an increase in plant height, leaf area, and dry weight of the leaves by 3.07 cm, 290.33 cm, 13.46 g, and 1.56 g, respectively, and caused an increase in the chemical properties of total soluble carbohydrates, total chlorophyll, and the percentage of NPK in leaves, which were 1.32 mg g-1 , 4.73 mg g-1 , 16.78%, and 1.32% and 20.39%, respectively.
