Two (2) months now after its establishment in August 8, the rice seedlings in the President’s Farm are growing healthily with the nourishing rain and sunshine in the Mariano Marcos State University (MMSU), City of Batac.

As a technology demonstration of newly-released and high-yielding rice varieties, the President’s Farm showcases five (5) inbred and five (5) hybrid rice varieties in this nearly two (2) hectare (ha) demonstration area in front of the College of Agriculture, Food, and Sustainable Development (CAFSD). This demonstration sustains the continuing effort of the University in empowering farmers and community folks with knowledge geared toward food security and sufficiency.

In partnership with the Philippine Rice Research Institute (PhilRice), the demonstration farm was established last August 8. The transplanting earned support from various officials from the MMSU and PhilRice, the Provincial Government of Ilocos Norte through the Provincial Agriculture Office, including the students of CAFSD who assisted in the transplanting.

Here are some information about the ten (10) inbred and hybrid rice varieties showcasing the 400- and 500-series rice varieties.

These rice varieties follow the recommended technologies of the PalayCheck System developed by PhilRice. In support to these technologies, Carrageenan Plant Growth Regulator/Promoter (CPGR) was applied, following the recommended application rate and time. CPGR was developed by the Philippine Nuclear Research Institute which can potentially increase yield by 15-20% and increase resistance to lodging.

The President’s Farm demonstrates agricultural breakthroughs in partnership with PhilRice. Since its establishment in 2017, the demonstration farm is initiated annually during the wet cropping season. With the initiative of President Shirley C. Agrupis and Dr. Santiago Obien, former President of MMSU and senior technical adviser of the Department of Agriculture, the demonstration farm is a highlight of annual Farmers Field Day conducted by the University with farmers invited all over the province.
