In the years 1982-1985 a field experiment was carried out concerned with the effect of the time of planting of the cloves and the trimming methods on the yield of garlic. The garlic cloves were planted on two dates: in autumn (20 Oct.) and in spring (20 March). In the experiment the effect of different methods of trimming, i.e. -trimming a 10 cm long seedstalk, -trimming of the seedstalk at the stage of an upright shoot, -no trimming, on the garlic yield was investigated.

The time of planting had a significant effect on the size of the total and marketable yield. When the bulbs were planted in autumn the former increased by 3.13 t ha-1 and latter by 2.93 t ha-1 in comparison with the yield of spring planted garlic. Trimming favourably affected the yield. The highest total and marketable yield was obtained when the seedstalk was trimmed at the stage of an upright shoot (10.07 and 9.42 t ha-1 respectively). Significantly lower yields were obtained in the control combination, where no trimming was carried out, the total yield being 7.69 t ha-1 and marketable yield 7.48 t ha-1. When applying this method of garlic cultivation an additional yield of bulblets (the mean yield was 2.02 t ha-1), which are a very good reproductive material, was obtained.
