STRAWBERRY IRRIGATION AND FERTILIZER TRIAL

 E. E. Albregts
 Associate Professor (Horticulturist)


Objective:


To determine water application rates with drip irrigation on several
nitrogen fertilizer sources and to monitor fertilizer availability
and leaching as well as crop response.


 A drip irrigation system using Viaflo tubing is placed in center of all beds.
This is the sole source of water for the beds except for rain and when plants are
protected from frost. The 3 rows on west receive 0.8 inches of water a week while
the 3 rows on the east receive 0.4 inches of water per week. The tubing, in all
instances but one, is placed above the fertilizer. Fertilizer nitrogen was applied
at 200 lbs/acre.
