                                 2.3) Barn leakages affect Jasmine rice quality, especially the increase in chalky grain
                       percentage. Thus, examining leaks and repair the before storage is necessary in order to preserve
                       the quality of Jasmine rice.
                                 2.4) The quality of Jasmine rice in sun-covered barns or sheltered by houses or trees tends
                       to be higher,  especially as measured by the lower chalky grain percentage. Therefore, the sheltering of
                       barns is a general principle that should be followed to preserve Jasmine rice quality effectively.
                                 2.5) Rice storage in tin-barns produces the lowest moisture content, which affects the
                       stored rice  weight.  Therefore,  farmers  should  avoid  storing  rice  in  such  granaries  because  of  the
                       incremental cost from the most rice weight, and the decrease in the quality of most fragrances.

                                 2.6) Using-coated sacks for Jasmine rice storage in every site reduced the overall quality
                       of Jasmine rice, as measured by high humidity, low head rice percentage, high broken rice percentage,
                       and low 2AP. Therefore, farmers should avoid using-coated sacks for Jasmine rice storage.

                                 2.7) Jasmine rice storage methods needed to maintain high quality are different in
                       each site; therefore, farmers should select the proper storage method as follows:
                                     - For Jasmine rice wooden-barn storage, used sugar sacks or used livestock feed
                        sacks  are  preferred  because  they  increase  the  head  rice  percentage,  lower  the  broken  rice
                        percentage, preserve fragrances, and deliver higher revenues compared with other storage methods.
                                     - For Jasmine  rice tin-barn  storage, used  livestock feed  sacks, mesh  bags,  or
                        piling storage are preferred because of the high head rice percentage and amount of 2AP they
                        produce compared with other storage methods.
                                     - For Jasmine rice house-kept storage, used livestock feed sacks are preferred
                        because of the high head rice percentage, low chalky grain percentage, and high amount of 2AP
                        compared with other storage methods.

                                     - Jasmine rice storage that uses used livestock feed sacks provides better quality
                        preservation compared  with  other methods,  and  the  incremental  cost  is  lower  than  other
                        methods so farmers would gain more net profit from the storage.
