Philippines - Corn Production Survey 2016

Philippines Corn Production Survey 2016

Agricultural Survey The Corn Production Survey (CPS) 2016 covered the April 2016, July 2016, October 2016 and January 2017 Rounds of the 62nd year of the quarterly survey. CPS is one of the two modules of the Palay and Corn Production Survey (PCPS). The other module is the Palay Production Survey (PPS).

The generation of production statistics on palay and corn through the quarterly Rice and Corn Production Survey (RCPS), now known as the Palay and Corn Production Survey (PCPS) dates back to as early as 1954 when the former Bureau of Agricultural Statistics (BAS) was still a division (Agricultural Economics Division) of the then Department of Agriculture and Natural Resources (DANR).

The RCPS has for its predecessors, the Crops and Livestock Survey (CLS), 1954-1968; the Integrated Agricultural Survey (IAS), 1968-1985; and the Rice and Corn Survey(RCS), 1985-1993. Prior to 1986, the RCS employed a two-stage stratified sampling design with municipality as the domain. In 1986, the RCS adopted a three-stage sampling design with province as the domain. In 1989, the RCPS design evolved from a statistical research undertaken jointly by the former Philippine Statistical Association (PSA), now known as Philippine Statistical Association, Incorporated (PSAI) and former Bureau of Agricultural Statistics (BAS) under a grant from the USAID. It was conceived as an improvement to the RCS with a completely different sampling frame and design.

The new RCPS design was officially adopted in July 1994. The design used the results of the 1991 Census of Agriculture (CA) as basis for sampling frame and is still being implemented up to the present.

Despite the long history of this quarterly survey, it was continuously improved in design and contents. Thus, in 2007, an updating of the list of farming households in the CPS sample barangays was made. Consequently, a new set of sample households was drawn. Likewise, modification in the contents of the survey was made and implemented in December 2007 (January 2008 Round). Also, starting this round, the name of the survey was changed to Palay and Corn Production Survey (PCPS).

The improved Corn Production Survey, January 2008 Round, underwent further changes on sample status and terms and concepts used. Hence, revisions of the questionnaire were made and a supplementary manual of instruction was provided for the CPS April 2008 Round.

The continuous efforts in developing approaches and methodologies in estimating corn statistics had been done, particularly, the CPS questionnaire. As early as 2010, the proposed revision of the CPS questionnaire was included in the workplan of the TWG on Cereals Statistics. In the succeeding quarterly meetings of the TWG, the Group reviewed the current CPS questionnaire and made sure that the same items were included in the propsed questionnaire. The pre-test was conducted in June 2011. The issues encountered, recommendations/suggestions and agreements by the TWG on the pre-test of the questionnaire and those raised during the National Management Consultative Meeting (NMCM held last June 2011 were presented to the body for assessment. Refinements were made in the questionnaire based on the results of the assessment. The major features of the new sets of questionnaires are: shift from barangay level to farm level questionnaire i.e., from a maximum of five (5) households to one (1) household per questionnaire; change in questionnaire format; more detailed sample status categories; defined types of corn; inclusion of items on labor inputs; and application of organic pesticides. These new sets of questionnaires was implemented starting April 2012 survey round of the CPS.
