Wpływ wilgotności gleby na plon cebul tulipanów [Influence of soil moisture on the yield of tulip bulbs]

The experiments were conducted in Wagner's pots on light loamy sand. The largest yields were obtained when moisture content was of 50 and 60 per cent capillary water capacity during the whole growing period. The smallest yields were obtained when the drought of the soil (20 per cent capillary water capacity) was used during the whole growing period or when it was used at the growing time of young bulbs, viz. after flowering time
