California Code, Code of Civil Procedure - CCP § 1263.250

(a) The acquisition of property by eminent domain shall not prevent the defendant from harvesting and marketing crops planted before or after the service of summons. If the plaintiff takes possession of the property at a time that prevents the defendant from harvesting and marketing the crops, the fair market value of the crops in place at the date the plaintiff is authorized to take possession of the property shall be included in the compensation awarded for the property taken.

(b) Notwithstanding subdivision (a), the plaintiff may obtain a court order precluding the defendant from planting crops after service of summons, in which case the compensation awarded for the property taken shall include an amount sufficient to compensate for loss caused by the limitation on the defendant's right to use the property.
