2010 Annual Interpretive Summary

Cantaloupe Fertilizer Source Trial, 2010

Cantaloupe growers have shown interest in using new sources and forms of N fertilizer that have provided promising research results in wheat and corn. The objective of this trial was to evaluate the performance of two products containing S — ammonium sulfate-nitrate (ASN, 26-0-0-14) and a 14-5-8.4-7.5 product — in comparison to a standard ammonium nitrate control. For cantaloupe grown with a black plastic mulch, fertilizers were applied on the soil surface prior to laying the mulch.

In 2010, all three treatments produced similar yields of about 11 to 12 t/A. There appeared to be no response to applied S. MD-13
