A Time Series Analysis of the Price Production of Carrotsin the Philippines
Employing ARIMA Modeling
1. INTRODUCTION
1.1 BACKGROUND OF THE STUDY
Carrots, along with other crops, dominate crop production and export in the Philippines, where
agriculture plays a significant role in the country's economy. The Philippines has one of the most
vulnerable agricultural systems to monsoons and other extreme weather events, which are expected
to cause more uncertainty there than climate change impacts, according to the World Bank, which
estimates it will currently employ 23% of the Philippine workforce by 2021. The Food and
Agriculture Organization has however, the policy has been hailed as one of the most aggressive in
reducing risk.[3] Carrots are a crop grown primarily for their edible, fleshy roots. Carotene, a
precursor to vitamin A, is abundant in its root.
Carrots are often grown taller because their roots require cold temperatures to develop. Carrots
will grow well and produce quality roots when the temperature is between 60-60°F (15.6°C-
18.3°C). Long, slender roots with a pale hue develop at higher temperatures. Carrots do not prefer
clay loam to sandy loam, although it is friable and has good drainage. It cannot grow in soil that is
too acidic. The best results are obtained in the pH range of 6.0 to 6.8, with extremely poor yields
at pH 5.2. Avoid hard and thick soil as it makes root problems more likely. Various colors such as
white, yellow, orange, purple, and violet are found in carrots. There are many variations, but there
are four main types: Nantes roots are 15 cm long, uniform in diameter, and have a blunt tip;
Imperator roots are long (2325 cm), have narrow shoulders and taper towards the tip. Typically,
Royal Chantenay has a huge, obviously colored center, large shoulders and is short (13 cm).
Danvers is a processing variety used for dicing and slicing that is huge (28 cm) and has medium-
, length roots (18 cm). [4]
