ABSTRACT
Two field experiments were conducted during 2019 and 2020 summer seasons at the experimental station of national research center, Al-Nubaryia district, El-Behaira Governorate, Egypt, to study the effect of Phenyl alanine and Aspartic acid foliar fertilizers at rates of (0.0, 50, 75 and 100 ppm) on morphological characters, photosynthetic pigments, seed yield and its components as well as seed quality of groundnut grown under sandy soil. Results indicated superiority of aspartic acid over phenyl alanine on increasing different growth parameters, chlorophyll b, biological and seed yields/plant, biological, seed and oil yields (kg/fed.), % of carbohydrate in peanut seeds. Meanwhile, phenyl alanine was superior on increasing carotenoids, indole acetic acid, phenolics, free amino acids, flavonoids, Lycopene, ß-Carotene contents, antioxidant activity expressed as (1,1-diphenyl-2-picrylhydrazyl DPPH %) and shilling percentage. In addition, aspartic acid and phenyl alanine with various levels caused significant increases in growth and seed yield quantity and quality of peanut plants through increases in photosynthetic pigments, indole acetic acid, phenolics and free amino acids contents. Aspartic acid was more effective than phenyl alanine, Foliar treatment with 100 mg/L aspartic acid increased oil yield (700.36 over 568.05 ton/fed.) and seed yield (1531.98 over 1253.49 kg/fed.). Finally, it can conclude that using aspartic acid and phenyl alanine as foliar treatment improved growth and yield of ground nut plants under sandy soil.
RESUMO
Dois experimentos de campo foram conduzidos durante as temporadas de verão de 2019 e 2020 na estação experimental do centro nacional de pesquisa, distrito de Al-Nubaryia, província de El-Behaira, Egito, para estudar o efeito de fenilalanina e fertilizantes foliares de ácido aspártico a taxas de (0,0, 50, 75 e 100ppm) em caracteres morfológicos, pigmentos fotossintéticos, rendimento de sementes e seus componentes, bem como qualidade de sementes de amendoim cultivadas em solo arenoso. Os resultados indicaram superioridade do ácido aspártico sobre a fenilalanina no aumento de diferentes parâmetros de crescimento, clorofila b, rendimento biológico e de sementes/planta, biológico, de sementes e óleo (Kg/alimentado), porcentagem de carboidratos em sementes de amendoim. Enquanto isso, a fenilalanina foi superior no aumento de carotonóides, ácido indolacético, fenólicos, aminoácidos livres, flavonóides, licopeno, teores de B-caroteno, atividade antioxidante expressa como (1,1-difenil2-picrilhidrazil DPPH%) e porcentagem de shilling. Além disso, ácido aspártico e fenilalanina com vários níveis causaram aumentos significativos no crescimento e produção de sementes, quantidade e qualidade de plantas de amendoim através de aumentos nos teores de pigmentos fotossintéticos, ácido indolacético, fenólicos e aminoácidos livres. O ácido aspártico foi mais eficaz que a fenilalanina. O tratamento foliar com 100 mg/L de ácido aspártico aumentou o rendimento de óleo (700,36 sobre 568,05 ton./alimentado) e o rendimento de sementes (1531,98 sobre 1253,49 kg/alimentação). Finalmente, pôde-se concluir que o uso de ácido aspártico e fenilalanina como tratamento foliar melhorou o crescimento e a produção de plantas de amendoim em solo arenoso.
