The California Crop Weather report from the National Agricultural Statistics Service Field Office in Sacramento, Calif., released May 15, 2012.
At the start of the week of May 7, a high pressure ridge stretched over Northern California while upper level low pressure moved across Southern California.This created dry and warm weather across the North and slightly cooler but dry weather over the South.
High pressure developed over the state through midweek. The low over Southern California slipped into Mexico. This combination brought warm temperatures statewide.
On Wednesday evening, a dry cold front moved across the state.This system brought no precipitation and hardly any cloudiness, but it did result in a slight cooling trend for a couple of days.
By Friday, high pressure redeveloped and brought warmer temperatures to the entire state for the weekend.Virtually no precipitation was reported this week across California.
Warm and dry conditions aided the maturation progress for the wheat crop.The entire crop was virtually headed as harvest started throughout the state.Some early-planted wheat was cut for hay and silage as conditions were rated mostly good to excellent.
Oat hay cutting continued.
Alfalfa growers advanced to the second cutting in the Central Valley while some producers treated the crop for alfalfa weevil.
Warmer soil temperatures benefited cotton as producers were nearly finished planting the crop. Early-planted cotton emerged at a rapid pace.
Corn showed good development.
Rice plantings continued.
Plum, prune, peach, apricot, and nectarine fruit progressed and developed as peaches and prunes produced heavily.Harvest continued in early peach and apricot varieties.
Cherry fruit developed as growers sprayed for the oriental fruit fly.Early cherry varieties were close to harvest in the San Joaquin Valley (SJV).
Weed treatments and bloom spray applications continued in stone fruit orchards.
Grape and kiwi vines grew fast as temperatures increased while shoot thinning started in grape vineyards.Grapes bloomed in early varieties and locations while some fruit were developing.Mating disruptions for the European grapevine moth have been put up in high risk vineyards.
