Productivity of fennel grown in newly reclaimed soils as affected by humic acid and amino acids treatments

10.21608/mjard.2025.466497

Abstract

This research was undertaken in the two seasons 2023/2024 and 2024/2025 in a private Farm at Balansoura village, Abu Qurqas district, El-Minya Governorate, Egypt to test the response of fennel plant grown in new reclaimed soils to humic acid (0.0, 1.0, 2.0 and 4.0 g/l), amino acids (0.0, 0.5, 1.0 and 2.0 ml/l) and their interaction treatments.
The findings pointed out that all examined vegetative growth characters (plant height, number of main branches per plant, and herb dry weight per plant), yield and its components (the number of umbels per plant, the weight of 1000 fruits, and the fruit yield per either plant and per feddan), essential oil productivity (essential oil percentage and its yield per plant and per feddan) and some chemical constituents (chlorophyll a, b and carotenoids contents and NPK%) of fennel were considerably increased by all used treatments concentrations of humic acid and/or amino acids facing the control throughout both seasons. The treatment of humic acid at 4.0 g/l and amino acids at 2.0 ml/l produced the highest values.
