| Abstract | ||||
| A POT experiment was carried out at the green house of Fertilization Technology Department to investigate the effect of salinity through irrigation water (0.0 and 4000ppm NaCl) and foliar feeding with chelated 12% Fe, Zn and Mn in the form of EDTA each at rate of 1g /L as individual nutrient in addition, to mixture of them on growth and macro and micronutrients uptake of bean bean (Phaseolus vulgaris). Results revealed that salinity resulted in significant reduction in dry weight. However, foliar feeding showed significant increments in the bean dry weight. Moreover, normal soil condition in combination with foliar feeding with the mixture of micronutrients achieved the highest dry weight increments Results also showed that salinity had significant negative effects on micronutrients uptake, while it had no marked effects on macronutrients uptake except K where salinity markedly reduced its uptake. Foliar feeding with micronutrients treatments either as individual nutrient or mixture of them showed significant increases in macro and micronutrients uptake. Spraying bean plants with the mixture on micronutrients showed the highest marked increments as compared with control (water foliar spray) and the other micronutrient treatments. Moreover, the interaction between salinity and micronutrient treatments on macro and micronutrients uptake was significant, where; most of calculated macro and micronutrients uptake showed the highest values by spraying bean plants with the mixture treatment and under the normal soil condition. The only exception was N uptake which calculated in bean, stem where, the highest value resulted from the spraying plants with Fe in combination with normal soil condition. | ||||
