public void update_picklist (string session_id, string client_id, string current_object , string current_field, string new_value, string custom, string label, string controlling_field, string controlling_field_value){
    string SoapBody = '<?xml version="1.0" encoding="UTF-8"?>';
    SoapBody += '<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">';
    SoapBody += '<S:Header>';
     SoapBody += '<SessionHeader xmlns="http://soap.sforce.com/2006/04/metadata"> ';

         }
       
         SoapBody += '<picklistValues>';
         SoapBody += '<fullName>'+new_value+'</fullName>';
            if (controlling_field_value != '-none-')
            {
              soapbody+= '<controllingFieldValues>'+controlling_field_value+'</controllingFieldValues>';
            }

          SoapBody += '<sorted>false</sorted>';
        SoapBody += '</picklist>';
        SoapBody += '<type>Picklist</type>';
    
                
           SoapBody += '</metadata>';

       SoapBody += '</update>';
      SoapBody += '</S:Body>';
    SoapBody += '</S:Envelope>';
    
    
    system.debug('soap envelope============================================='+SoapBody );
    
    
       HttpRequest req= new HttpRequest(); 
            req.setEndpoint('https://ap1-api.salesforce.com/services/Soap/m/25.0'); 
            req.setMethod('POST'); 
            req.setHeader('content-type', 'text/xml; charset=utf-8');  
            req.setHeader('SOAPAction', 'https://ap1-api.salesforce.com/services/Soap/m/25.0' );
            req.setBody(SoapBody);
            Http ht = new Http(); 
            Httpresponse response = new Httpresponse();
            response = ht.send(req);
            
            system.debug('-----------------------------'+response);
           // return 'success';

 }

 

Pass all valid values in this function  and it will insert new picklist in metadata
