| Abstract | ||
| A study was conducted at Etay Elbaroud Research Station, Agriculture Research Center, MALR, Egypt, to investigate the effect of magnetic saline irrigation water on growth of two groundnut genotypes. The experiment was carried out in randomized complete block design in a split-split-plot arrangement with three replicates. The main plot represented by four salt concentrations (0, 25, 50 and 100 mM NaCl), the sub-plot was two groundnut genotypes (Giza 6 and N.C.) and the sub-subplot was two treatments (with or without magnetized irrigation solution). Seeds were sown in pots containing 0.5 Kg pre-washed quartz sand and irrigated three times per week by adding 100 mL of irrigation solution consisting of base nutrient solution and the salt level exposed to with or without a magnetic field, to each pot. After three weeks from sowing the whole plants were collected. The results indicated that increasing salt stress decreased the all growth parameters and shoot/root ratio on fresh and dry weight basis of the two groundnut genotype. However, moisture content of whole plant, shoots and roots were increased with increasing salt stress. Electrolytes leakage generally decreased with increasing salt stress. Chlorophyll a, b and total chlorophyll content increased at high level of salt stress (100 mM NaCl). The N.C. genotype was more sensitive to salinity than the Giza 6 genotype for most growth attributes. The magnetized saline irrigation water had no significant effect on alleviation of salt stress to the two groundnut genotypes. | ||
