Effect of irrigation with magnetically treated water on faba bean growth and composition.

Abstract

A pot experiment was conducted to investigate the effect of irrigation with different magnetized water on faba bean (Vicia faba L) growth and composition. Prepared sandy soil was packed in plastic pots (5 kg capacity) at a rate of 4 kg. Faba bean seeds were cultivated at rate of 4 seeds/pot. After the germination,faba bean plants were thinned into 2 plants/pot. Both sewage sludge compost (SSC) and tricalcium phosphate (TCP) were added to the soil at a rate of 25 tones ha-1 and 720 kg ha-1,respectively. Irrigation water sources were magnetized by passing throws a magnetic field 1000 gauss magnetron unit of 0.5 inch diameter. Plant length, shoot and root fresh and dry weights of faba bean were significantly increased by using the different magnetized irrigation water sources compared with the non-magnetized water. Only root fresh and dry weights of faba bean plant were significantly increased by using magnetized irrigation water and the different soil organic and inorganic treatments. On the other, plant length, shoot and fresh and dry weights were not significantly affected by the combined effect of magnetism and soil treatments. Shoot N, P and K contents and uptake of faba bean were significantly increased by the individual and the combined application of SSC and TCP to soil compared with untreated soil. Shoot N, P and K contents and uptake of faba bean was significantly increased by using magnetized irrigation water compared with the non-magnetized water.Generally, using different magnetized irrigation water sources, soil salinity, soluble cations and anions were significantly decreased by using magnetized water. Soil salinity, soluble cations and anions were significantly increased by adding both the individual and the combined SSC and TCP. Available soil N, P and K were significantly increased by adding both the individual and the combined SSC and TCP. Using different magnetized water sources, available soil N, P and K were significantly increased.
