Abstract

The research concerned the effect of drying out of soil on the yield of a number of vegetables and the practical use of irrigation.

From the extensive literature published in various countries on this aspect of irrigation research, a series of soil moisture conditions for vegetables (early potatoes, carrots, broad beans, beet root, endive, lettuce, cauliflower, dwarf beans, Scottish kale, Savoy cabbage, spinach and strawberries) was achieved on a trial plot of rather drought-susceptible soil by preventing natural precipitation by removable glass-covers and by irrigation with mobile sprinkler booms. These conditions varied in the limit of drying measured as percentage soil moisture on a weight basis and expressed as average moisture tension (pF), either constant for the entire growing period or varied at different stages of crop development (sensitive period experiments). In other experiments drying of the soil was slowed down by small daily irrigations based on estimated evaporation in the previous 24 hours or at a fixed amount.

The yield and crop quality was strongly correlated with the average pF, however sometimes as optimum curve for parts of the growing period.
