52 MODERN STRAWBERRY GROWING 
periments conducted by Professor Goff of 
Wisconsin: 
In 1894, irrigated acre yield was 214.6 bushels; in 
1895 irrigated acre yield was 279.9 bushels; mean yield, 
243.8 bushels. 
In 1894 the non-irrigated yield was 109.3 bushels; in 
1895 the non-irrigated yield was 32.3 bushels; mean 
yield, 70.8 bushels. 
This showed a difference in their mean 
yield of 173 bushels in favour of the irrigated 
patch. Not only was there a larger yield, 
but the quality of the fruit was improved, 
and the berry being larger was more salable. 
When irrigation is to be practised there 
are several points which determine how 
much water should be applied at each time. 
1. How dry the soil is. The drier the 
soil the more water is needed to thoroughly 
moisten it. 
2. Whether or not the soil is leachy, or 
otherwise unable to conserve water. Leachy 
soil requires irrigation more often. 
3. Whether or not the feeding surface for 
the roots is shallow or deep. The deeper and 
the finer the soil texture the more moisture 
it is capable of holding. 
4. The amount and rate of the movement
