A Ph.D. dissertation was discussed at Al-Musayyab Technical College at Al-Furat Al-Awsat Technical University (Effect of Nanonutrient treatment on growth and yield of two Fava Bean cultivars under salt stress).
The study presented by researcher Abeer Mohammed Al-Idani from the Department of Plant Production Techniques aimed to determine the best concentration of nano zinc spray and its reflection in improving growth indicators and quantitative and qualitative yield of fava beans, and reducing the effect of salt stress on the growth and yield of Fava beans by using varieties that tolerate salinity and are characterized by giving the best vegetative and quantitative growth indicators, and studying the binary and triple interactions of experimental factors in the studied indicators of fava beans.
The study concluded that the plants treated with salt in the two experimental sites were significantly superior to the other concentrations in some indicators of vegetative growth and yield, as well as the Spanish variety Fito. Feeding fava bean plants with nano zinc contributed to improving the indicators, and the triple interaction between the experimental treatments had a significant superiority in most of the characteristics. The study recommends planting the Spanish variety Fito in Iraqi lands due to its tolerance to environmental conditions, especially salt stress, compared to the Italian variety Franchi, and expanding the use of nano fertilizers, especially foliar spraying with nano zinc at a concentration of (75 mg.L-1), which achieved the highest results in both sites.
