[12] The trend is similar nationwide with BS Agriculture programs offered by higher education institutes in the country having the least enrollment.

[13] To educate farmers in better farming methods, the University of the Philippines Board of Regents purchased 72.63 hectares of land on the foot of Mount Makiling near Manila for the establishment of an agricultural school with Edwin Copeland as its first dean.

[9] Charles F. Baker replaced Copeland as dean in 1917 and oversaw the construction of new buildings and the acquisition of a 300-hectare Agricultural Experiment Station.

[5] For three years, the college was home to more than 2,000 civilians, mostly Americans, who could no longer be imprisoned in the Santo Tomas Internment Camp.

In 1945, as part of the liberation of the Philippines, the US Army sent 130 11th Airborne Division paratroopers to Los Baños to rescue the internees.

However, Japanese reinforcements arrived two days later, destroying UPCA facilities[5][9] and killing some 1,500 Filipino civilians in Los Baños soon afterwards.

[15][16] UPCA became the first unit of the University of the Philippines to open after the war when it resumed classes on July 25, 1945, with Leopoldo Uichanco as dean.

[18] Further financial endowment from United States Agency for International Development (USAID) and the Mutual Security Agency (MSA) allowed the construction of new facilities while scholarship grants, mainly from the Rockefeller Foundation and the International Cooperation Administration-National Economic Council, paved way for the training of UPCA faculty.

[21] CA acquired 288 hectares of land in La Carlota, Negros Occidental in May 1964 by effect of Proclamation 250 of President Diosdado Macapagal.
