Abstract
The quality of rubber tapping technology was assessed at Memot Rubber Plantation Co., Ltd, located in Memot District, which is located on the east of the provincial capital of Tboung Khmum province, Cambodia. The research finding was conducted from March 20 to June 20, 2018 with 140 of rubber tappers and inspected 140 tapping tasks of tapping plots (6 tr/task ration with the length cut S/2 d3 7d/7 of the clones RRIM600 and GT1, 2008). The grading quality of rubber tapping technology was recorded. The factors with tapping technology quality and rubber bark consumption was determined the variable evidence and analyzed the relationship between eight factors with grade of rubber tapping technology quality. The results showed that 140 rubber tappers the assessed rubber tapping technology quality as following of a very good, good, fairly good, fairly, and poor grade approximately 13%, 4%, 18%, 22%, and 43%, respectively. Most of rubber tapping quality were in poor grade level such as 12.7A, 12.7B, 12.7C, 12.7D, 12.6B, 12.6C, 11.6C, 14.7B, 14.7C, 14.7D, 14.6C approximately 73.68%, 74.22%, 72.64%, 72.11%, 71.40, 72.23%, 71.27%, 71.82%, 74.55%, 72.60%, 65.30%, respectively. There were only two plots in fairly grade level such as 11.6B, 15.7C approximately 76.82%, 75.09%, respectively. Amongst of eight factors, there was X8 bark consumption had relationship with rubber tapping technology quality (Y) (P<0.05) and all of eight factors showed that (X4) horning of tapping knives, (X7) training, (X8) tapping quality had relationship with rubber bark consumption (Y) (P<0.05).
