Exrtremely hot and extended period of heat coupled with a below average cold October and heavy insect pressure early has meant for below average yields. The season was oone of the longest on record as crops tried to compensate for early poor retention. Then got caught by the extreme heat that went well into March. The Sicot 754BRF performed the best and dealt with the heat alot better than the other varieties.
