CAGAYAN VALLEY: It Leads The Way In Mechanized Rice Direct Seeding

This is the 8-row direct seeder from Korea Agricultural Machinery Industry Cooperative represented by Fitcorea company in the Philippines. It can finish four hectares in one day.

CAGAYAN VALLEY may now be considered as the place where you can find the most number of mechanical rice harvesters, especially in Isabela. The region is composed of Isabela, Cagayan, Nueva Vizcaya, Quirino and Batanes.

Today, Cagayan Valley is once again leading the way in adopting the mechanized rice direct seeding by adopting the latest model of the 8-row seeder from the Korea Agricultural Machinery Cooperative (KAMICO) represented by Fitcorea in the Philippines. Several such machines have been bought by the Department of Agriculture and are now being used by members of cooperatives.

The mechanized direct-seeding technology offers significant advantages to farmers. Foremost is that it can cut costs in several ways. First, it uses much less seeds than when direct seeding is done manually. Farmers usually use 150 to 200 kilos of seeds per hectare when they do manual direct seeding. On the other hand, direct seeding by machine requires only 40 to 80 kilos per hectare.

Mechanized direct seeding also cuts cost on labor and the job is finished much faster. The direct-seeding machine plants the seeds in equal distances and in straight rows. That means, it is possible to mechanize weed control if the use of herbicide is not done. In times of unavailability of farm workers, the direct seeder conveniently solves the problem.

Direct seeding also results in earlier harvest of the variety by one week to 10 days. Thus, the crop has a shorter exposure to possible inclement weather such as floods and typhoons.

In a one-year research a few years back, the Korean riding type seeder and the PhilRice drum seeder were evaluated at the PhilRice Central Experiment Station. It was found that the Korean direct seeder can finish seeding four hectares in one day while the PhilRice drum seeder can only seed one hectare in one day.

Results showed that Koreaโ€™s riding type seeder attained higher yield than the PhilRice drum seeder. This was due to better placement of seeds by the Korean seeder that resulted in good seedling emergence and crop growth. The placement of seeds is slightly drilled and covered with soil, and compact in one hill unlike the PhilRice drum seeder where the seeds are placed on the surface of the soil and slightly scattered.

The field should be thoroughly prepared and leveled if ย mechanized direct seeding is used.

For the wet season direct seeding, it is recommended that the field be well prepared and leveled to achieve good emergence of the seedlings and crop growth. The seeds are soaked for 24 hours and incubated for another 24 hours. Draining of the field should be done four days before seeding.

The performance evaluation of the Korean seeder and the PhilRice drum seeder was under the auspices of DA-PhilRice in collaboration with the Korea Project on International Agriculture (KOPIA) headed by director Dr. Kim Jae Duk.

Direct seeding can cut the cost of producing rice.
