I solve problem!
Your link: Problem while Adding or Editing Rows in a Dataset via API
has help me.
It was not obvious to refer to columns by name “DatasetColumnId_xxx”.

Now part of code:

    			'form_params' => [
				'dataSetColumnId_'.$columns[0]->dataSetColumnId => $tovar->id,
				'dataSetColumnId_'.$columns[2]->dataSetColumnId => $tovar->title,
				'dataSetColumnId_'.$columns[3]->dataSetColumnId => $tovar->description,
				'dataSetColumnId_'.$columns[4]->dataSetColumnId => $tovar->price->text 			
    			]
