| Abstract | ||||
| Two field trials were carried out during the two successive winter seasons of 2019/2020 and 2020/2021. The experiments were conducted in a Private Farm at Manshia Radwan District, Abou Kabir Region, Sharkia Governorate, Egypt. Onion cv. Giza 6 Mohassan was selected for this study at sandy loam soil . The aim of this work was to study and evaluate the role of some bio-stimulants on bulb yield of onion. The experiment was included 10 treatment groups as follows: 1) Dry yeast extracts (4 g/L), 2) Seaweed extracts (2 ml / L), 3) Garlic oil extract (2.0 ml /L), 4) Bee Pollen (2 g /L), 5) Dry yeast extract (2 g/L) + Bee pollen extract (1g L), 6) Foliar spray with potassium humate (1.5 ml/L), 7) Dry yeast (2 g /L) + seaweed extract (ml/L), 8) Garlic oil extract (1 ml/L) + Dry yeast extract (1 g /L) + bee pollen extract (1/2 g /L) + seaweed extract (1/2 ml/L), 9) Dry yeast extract (1 g /L) + bee pollen (1/2 g /L) + Seaweed extract (1/2 ml. /L),and 10) Control (without any addition). A randomized complete block design (RCBD) was used for these treatments (with three replicates). Results revealed thatthe treatment of garlic + dry yeast + bee pollen + seaweed extract, being the most effective in bulb yield of onion in both growing seasons. This treatment followed by the treatments of dry yeast + bee pollen + seaweed extracts, dry yeast + seaweed extracts, potassium humate and seaweed extracts, respectively. Conclusively, the treatment of garlic extract + dry yeast + bee pollen + seaweed extracts, followed by the combinations between them, and the treatment of potassium humate increased the onion bulb yield and its components under the same conditions of this study. | ||||
