Corn production in ARMM increased by 7.24 percent in 2018 

The total corn production in ARMM increased by 7.24 percent in 2018 to 902,566.96 metric tons (MT) from the 841,618.00 MT production in the previous year. More than half or 59.80 percent of corn in the region during this period was produced in Maguindanao, while 39.97 percent was produced in Lanao del Sur (Figure 1). The remaining less than one percent was produced by Sulu, Basilan and Tawi-Tawi. Corn production in Basilan, Sulu and Maguindanao increased by 24.73 percent, 17.47 percent and 15.04 percent, respectively. On the other hand, production in  Tawi-Tawi and Lanao del Sur decreased by corresponding rates of 32.73 percent and 2.60 percent (Figure 2).

Palay and Corn Production Survey

            Palay Production Survey and Corn Production Survey (PPS and CPS) are some of the major agricultural surveys conducted by the Philippine Statistics Authority (PSA). These generate estimates and forecasts on palay and corn production, area and yield and other production-related data that serve as inputs for policy making and programs on palay/rice.

            The data generated from this survey are disseminated through special releases, bulletin and publications, namely:

Special Release

  • Palay and Corn Situation and Outlook
  • Seasonally Adjusted Rice Production and Prices

Bulletin (quarterly)

  • Rice and Corn Quarterly Bulletin

Publication (annual)

  • Palay Production in the Philippines
  • Corn Production in the Philippines

 The collections of data of these surveys are undertaken by hired Statistical Researchers (SRs). The SRs are trained prior to field operation to ensure that the procedures and concepts are   understood. The training includes mock interviews and dry-run exercises.

 PPS and CPS are quarterly surveys which cover sample farming households in sample barangays in all provinces except Batanes and include Zamboanga and Davao City. These employ   replicated two-stage stratified sampling design with the barangay as the primary sampling unit (psu) and farming household as the secondary sampling unit (ssu). The barangays are stratified   based on their palay and corn area and are selected using probability proportional to size, (pps and cps) scheme. Four replicates, four independent sets of sample barangays per stratum are   drawn. From the selected barangays, households were drawn through systematic sampling.

 The data gathered in this survey are as follows: production, area planted/harvested and yield by ecosystem and seed type; usage of seeds, fertilizer and pesticides; source of irrigation water and   adequacy, monthly distribution of production and area harvested; farm household disposition of production; area with standing crop, farmer’s planting intention for the quarter; and awareness and   availment of palay and corn program interventions. The reference period for each survey round is shown below:

Survey Round Reference Round
April Round January to March
July Round April to June
October Round July to September
January Round October to December

Definition of Terms:

Palay Household – the sample household operates an agricultural land, whole or part of which is palay area within the nine-month period, or the land is temporarily in-fallow but the respondent declares that it is devoted to palay production. Specifically, any of the following conditions must be satisfied:

  1. Household harvested palay during the reference quarter;
  2. Household has standing palay crop in the farm;
  3. Household intends to plant within the succeeding quarter; and
  4. The land is temporarily in-fallow but the respondent declares that it is devoted to palay production.

Non-Palay Household – household operates an agricultural land which is not intended for/devoted to palay production, i.e., zero palay production, no standing palay crop and planting intention.

Corn Household – the sample household operates an agricultural land, whole or part of which is corn area within the nine-month period, or the land is temporarily in-fallow but the respondent          declares that it is devoted to palay production. Specifically, any of the following conditions must be satisfied:

  1. Household harvested corn during the reference quarter;
  2. Household has standing corn crop in the farm;

a.    Household intends to plant within the succeeding quarter; and

b.    The land is temporarily in-fallow but the respondent declares that it is devoted to corn production.

Non-Corn Household – household operates an agricultural land which is not intended for/devoted to corn production, i.e., zero corn production, no standing corn crop and planting intention.

Technical Notes:

                        Production refers to the quantity produced and actually harvested for a particular crop during the reference period. For palay and corn, harvest area refers to the actual area harvested/to be harvested during the reference quarter. Estimates and forecasts of production and harvest area of palay and corn are generated from the Quarterly Palay and Corn Production Survey (PCPS) of which there are four survey rounds in a year that is January, April, July and October. The following are the data taken from these surveys:

               a.      Production estimates of the previous quarter for each survey round;

               b.      Forecast one quarter ahead based on the standing crop; and

               c.      Forecast two quarters ahead based on planning intentions.
