52 MODERN STRAWBERRY GROWING 



perlments 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
