PRELIMINARY OBSERVATIONS ON THE PRODUCTION OF NEW HIGH YIELDING RICE VARIETIES AND TRADITIONAL RICE VARIETIES IN SUPHAN BURI, THAILAND

The actual location of the study area was in Suphan Buri Province, some 100 kilometers northwest of Bangkok, Thailand. A total of 153 rural households in six villages cooperated in the study. Forty of the rice farms were located in a deep water, broadcasted area where floating rice varieties are grown. The remaining 93 rice farms were in a transplanted rice area where many farmers were growing the new high-yielding rice varieties. The authors provide summary tables on the following topics: table of farms; planted area and varieties grown; farmers growing new varieties; area and variety planted for the 1970 and 1971 seasons. They include summary discussions of high yielding varieties, other new rice technology, research and costs of production.
