In an experiment conducted from October 2019 to July 2020, we examined whether the period of planting shallots has an impact on the quality and quantity of the crop. Shallots were planted in autumn (October 25th, 2019) and spring (March 12th, 2020) period, each time in four replicates, and four varieties were used: 'Jermon', 'Longor', 'Golden Gourmet' and 'Red Sun'. In the experiment, we found that the survival of autumn shallots was 30 % lower compared to shallots from the spring planting period, which could be attributed to higher rainfall in November (59.2 mm more than the long-term monthly average), in the period when roots are developing. In the autumn planting period, shallot yields ranged from 12.5 to 32.6 t/ha, while in the spring it was from 27.7 to 42.7 t/ha. We found that there was no statistically significant difference in the amount of yield, except for the 'Golden Gourmet' variety, where the yield was 24.7 t/ha higher in the spring planting period. The width of the bulbs did not differ statistically significantly in any variety. The height of the bulbs only differed statistically in the 'Red Sun' variety, where the height from the autumn planting period was 3.6 mm lower compared to the spring period. We also found that the planting date did not affect the time of harvest, as we collected both shallots from the autumn as well as the spring planting period on the same day. The total dry matter was 1.4 % higher in the spring planting period. Only the 'Golden Gourmet' variety from the autumn planting period had a 2.5 % higher dry matter content than the shallot from the spring period.
