EFFECTS OF IRRIGATION ON TUNNEL-GROWN STRAWBERRIES
The four-year results of irrigation trials conducted on this tunnel-grown crop near Bologna in northern Italy are reported. A Class A evaporimeter assessed the tested MET (Maximum Evapotranspiration) rates at crop coefficients in the tunnel; a non-irrigated control was employed from spring regrowth onwards in 1986 and 1987. Irrigation significantly increased strawberry yield and size only in 1987. The failure recorded in the other trial years was correlated to the lower evaporation rates registered and to the adeguate water table supplying the crop. Even in the year when the water table was lower, the crop irrigation requirement was only 1 100 m3/ha, far less than that normally supplied to the crops in this area.
