| Abstract | ||||
| A field experiment was carried out at the Agronomy Farm of Faculty of Technology and Development Zagazig University, Egypt, to Study the effect of Novatreen and potassen foliar on the grain yield and quality of soybean seeds. Soybean plants were sprayed with two foliar nutrients, at concentrations were 0.2% and 0.4 % respectively. All treatments significantly increased the grain yield and plant performance (No, of pods per plant, No, of seeds per pods and weight of 100 seeds) .Insoluble nitrogen contents recorded a slight decrease by foliar potassen. Total nitrogen in seeds was increased with novatreen foliar. The potassen foliar was increased water soluble protein content , while decreased the protein fraction solubilized in both acetic acid and 0.1N NaoH solvents. Also, novatreen foliar slightly decrease of total protein content. The pattern of soybean proteins showed two main fractions (7S and 11S globulins) with their constituting subunits. Oil content of soybean seeds slightly decreased with novatreen foliar, but potassen foliar increased the oil content of soybean seeds. A slight differences were noticed with acid values, saponification and iodine values. The highest values of both saponification and iodine were obtained by 0.2 % foliar potassen. Both foliars improved the contents of P , K and Na , but reduced the contents of Fe and Mn in seeds. Conclusively, It is recommended to spray the novatreen and potasen compound on the plants after 30 days of cultivation with a concentration of 0.4% to obtain the highest productivity of the seed yield as well as the quality of the protein content, oil and nutrients necessary for the process of metabolism in the plant. | ||||
