Philippines is an agricultural country. The geographical location of this country in the Tropic Tropic plays the major role to this fact. Aside Aside from rice, Filipinos Filipinos produce most of the crops crops that they use use to make make food that they serve serve in their their dining dining tables. tables. In the countryside, houses have different kinds of vegetables, fruits and root crops planted on their backyards. backyards.

This study is limited to the determination of the effect of the different colors of light such as red, yello!, blue, green, and !hite on the gro!th of the mongo plant (Vigna radiata) in terms of onset of true leaf, number of sprouts for mongo seeds and number of
leaves, sprout height and biomass for mongo sprouts. 7imulation of artificial lights !as implemented using cold frames covered !ith colored !ater cellophane to suit the light color needed then e1posed to fluorescent lamp.
