Chiang Rai farmers increase potato yields by 30 tonnes per hectare using drip irrigation.

by

The farmers of Chiang Rai have identified potatoes as the most lucrative of crops in comparison to other options for the region due to the high consumer demand in the food sector in the production of snacks.

PepsiCo is a key player in the industry of snacks provides support to more than 5,800 farmers in Thailand and facilitates potato cultivation across more than 6,080 acres in provinces like Chiang Mai, Chiang Rai as well as other provinces.

They thrive in colder conditions, and the ideal temperature is between 15-18 degrees Celsius. If temperatures rise above 21 degrees, growth on the stem increases while yields of tubers decrease. The most optimal conditions can be found at elevations at or near 800 meters. These cooler temperatures promote an optimal development of the tuber.

It is essential to manage water for the cultivation of potatoes. In the beginning, a small amount of water aids the germination process, however excessive moisture could cause rot. As plants develop they require more water and the demand is highest when the soil is absconding. The inconsistency of watering during the formation of tubers could cause problems. Furrow irrigation is a traditional method that can result in damaged skin as well as a higher likelihood of the onset of rot. To ensure the health of tubers the watering should stop at least two weeks prior to the harvest.

In recognition of the significance of water efficiency PepsiCo works with local partners to educate Thai farmers on climate adaptation. Training covers soil improvements as well as pest control, as well as effective irrigation methods such as drip systems that ensure continuous water distribution while decreasing expenses.

PepsiCo has established 19 model farms to demonstrate sustainable potato farming techniques. These farms operate under contractual agricultural agreements that supply farmers with a guarantee on purchase price.

Ms. Anuwat Phrommi, a farmer of potatoes in Chiang Rai, transitioned from the furrow system to drip irrigation, thanks to PepsiCo’s help. The change increased the yields by 30 tons per hectare, cut down on the use of water by 40 percent as well as slashed labor costs by 23 percent.

In order to ensure the health of soil after the wet season, Anuwat buries crop residues instead of burning the residues. The harvest starts in the beginning of February. Premium potatoes are being sold to PepsiCo and lower-quality produce is sold to local markets.
