The most significant medicinal and aromatic plants in Egypt and the world are caraway (Carum carvi L.), anise (Pimpinella anisum L.) and cumin (Cuminum cyminum L.). In vitro trails, completely inhibited of mycelial growth and spore germination was achieved with Thyme and Rosemary at 0.75 % for A. flavus and F. verticillioides while at 1.0 % for A. niger. While in vivo, trails, Thyme and Rosemary
essential oils was mixed individually with wheat barn and tested seeds were treated with mixture at rate of 0.00, 5.0,10.0.15.0,20.0 and 25.0 g/kg seeds. Results showed that all tried concentrations of essential oil carrier contact decreased the natural infection of tested seeds. The protective impact of Thyme and Rosemary essential oils carrier against A. flavus infection was assessed after 90 days of storage. Results showed that all tried concentrations of essential oil carrier decreased the artificial infection with A. flavus of all tested seeds. The highest inhibited was achieved with Thyme and Rosemary carrier at 25.0 g /kg seeds which decreased the infection more than 88.0, 89.0 and 91.0 %, for cumin, anise and caraway respectively. Followed by both essential oils carrier at 20.0g/kg seeds which reduced the infection more than 76.0 % for all tested seeds. Thyme and Rosemary carrier at 25.0 g /kg seeds recorded lower percent of the germination seeds for all tested seeds.

Two field experiments were carried out in consecutive winter season of 2022 and 2023 at the Research and Production Station of the National Research Centre at the Nubaria site in Beheira Governorate, Egypt, to determine the response of pea (Pisum sativum L.) to foliar application of humic acid and phosphorus fertilization on growth, yield parameters and nutrients content of pea plant. Phosphorus fertilization rates (0, 38, 76 and 114 P2O5 kg ha-1) were used as the main factor, while K-humate concentrations (0, 1000 and 2000 mg l-1) were used as a second factor. The results demonstrated that applying phosphorus fertilizer and spraying K-humate had a substantial impact on growth and production. The growth and yield of peas in two consecutive growing seasons were impacted by increasing the rate at which K-humate at different concentrations was applied while also increasing the rate at which phosphorus fertilizer was applied. For the pea growth and yield coordinates, the experimental treatment (K-humate at 2000 mgl-1 + 114 kg P2O5 ha-1 of phosphorus fertilizer) received the greatest values. The nitrogen, phosphorus, and potassium content of pea seeds increased as the concentration of K-humate spraying increased. The study's findings highlight the significance of phosphorus fertilization and show that applying K-humate spray to plants while they are growing can boost the fertilizer's efficacy and impact on pea plants that are irrigated with salty water.
