The drip-type watering system was more economical than the previously developed collapsible seedling nursery, which has six developed locally fabricated microsprinklers on a vertically positioned pipe that was moving back and forth. The new system, however, needs to be further evaluated since problems with eroded soil and lodged seedlings had been observed. A seed treating machine that can uniformly apply grain protectants (in fine mist) on seeds at a rate of 1 to 1.5 liters per ton of seed was designed, fabricated and tested using F1 hybrid seeds. At this rate, no significant increase in seed moisture content was observed after treatment. Using commercially available grain protectants, Deltamethrin and Pirimiphosmethyl (at a rate of 1 g and 7 g a.i.), the unit was extensively used in treating hybrid seeds stored at PhilRice CES. PhilRice Midsayap also used another unit in treating hybrid seeds. A storage bin (2-ton-capacity) was designed and fabricated, together with a movable bucket elevator that facilitates the loading of seeds into the storage bin. Although this system is still to be evaluated, it is expected to reduce time, labor cost, and grain losses during handling, storage, and pest control administration
