Abstract
Along with their leaves and tubers, Jerusalem artichoke is a vital source of nutrition food, fuel, animal feed, and medicine. In the two consecutive spring seasons of 2023 and 2024, a field trail was conducted at the Orabi Association, a private farm in the ElKaluobia Governorate, Egypt, to examine a different number of shoots cut and spraying with some concentrations of amino acids mixture on foliage production and tuber yield of Jerusalem artichokes (Helianthus tuberosus L) Local cv. A split plot design was adopted in this experiment, including the main plot factor, which contained the cut treatments {the first cut after 60 days of germination, and the second cut after 60 days from the first one). The subplot factor included the amino acids mixture concentration (0, 1.5, and 2.5 cm/L). The results indicated that the number of lateral shoots was considerably increased by the second cut of the shoots without the amino acids mixture. Fresh and dry weight improved by the control and amino acids mixture at 2.5 cm/L treatments. The inulin and foliage were greatly enhanced by the second cut of shoots and spraying an amino acid mixture at 1.5 cm/L. In general, the production and quality of Jerusalem artichokes were greatly increased by spraying a 2.5 cm/L amino acid mixture. The yield rates recorded 64.43% and 47.43% of the first and second cuts. By increasing the plant's capacity to produce leaves, these changes could help Egypt for summertime animal feed shortfall and lower prices by replacing fodder crops.
