| Abstract | ||
| A field experiment was carried out during the two consecutive seasons 2021/2022 and 2022/2023 at the Nursery of ornamental plants, Faculty of Agriculture, Minia University. The experiment was arranged in a completely randomized block design in a split plot arrangement with 3 replicates. Main plots including planting dates at 15th Oct., 1st Nov., and 15th Nov., while sub-plots including amino acids at 0, 1, 2 and 3 ml/l and seaweed extract at 1.5, 3 and 4.5 m/l, plus the control. In both seasons, plant height, branches number, herb dry weights, seed yield/plant and /fed. as well as fixed oil productivity and photosynthetic pigments were significantly affected with planting dates and growth stimulant substances applications. Also, there was a significant interaction between both main and sub-plots treatments, except herb dry weight in the first season and number of branches in the second seasons as well as chlorophyll b and carotenoids in both seasons. In general, the best interaction treatments were obtained during plants sown in the first date and sprayed with amino acids at 3 ml/l or seaweed extract at 1.5 ml/l. | ||
