Effect of boric acid and some calcium and magnesium salts in the chemical and mineral composition of barley grain

The study was conducted in the wiry house in order to study the effect of treated soil with (Boric acid, Magnesium sulphat, calcium chloride) with concentrations (0.1%, 0.2%, 0.3%)Kg soil each one treated separately.on yield, carbohydrate, protein and metal composition of barley cultivar (402).<br /> Results showed that treated soil in (calcium chloride) especially in concentration (0.2%) led to improve the yield by increasing the number of the spike grains, weight of crop /plant, biological yield spike length and weight. Also led to significant increase in protein contents in barley grains in comparison with other treatment.<br /> ABSTRACT<br /> <br /> The study was conducted in the wiry house in order to study the effect of treated soil with (Boric acid, Magnesium sulphat, calcium chloride) with concentrations (0.1%, 0.2%, 0.3%)Kg soil each one treated separately.on yield, carbohydrate, protein and metal composition of barley cultivar (402).<br /> Results showed that treated soil in (calcium chloride) especially in concentration (0.2%) led to improve the yield by increasing the number of the spike grains, weight of crop /plant, biological yield spike length and weight.
