Rice production in the Philippines fluctuates periodically due to various constraints including nutritional imbalances in soil, climatic factors, biotic factors, and social and economic challenges. The population of the Philippines also continues to increase each year, putting pressure on rice supply. While technological advances like combine harvesters and drones have the potential to increase yields, factors like high production costs, drying problems, and lack of resistant rice varieties currently limit further growth in rice production. Modern techniques such as hybrid rice also offer opportunities for improvement, but challenges around adoption and sustainability remain.

4. Rice Demand
• Based on the study, our country feeds 21 individuals per hectare as to compared to Thailand,
which only feeds 7 individuals per hectare.
• Rice is the most common source of carbohydrates, its account 20% of their household budget
• The country’s rice farmers is also aging and becoming less and less. The average of farmers is
55 years old (2019 study), based on the statistic of PhilRice which interviewed 4,000 farmers
across the country.
• Based in the interview, most children on the farmers are not following their father’s footsteps,
as working in the rice field is laborious and less appealing for the younger age. Most parents
encourage their children to enroll other courses in college, instead of taking Agriculture.

Management and maintenance for sustainability
Development
The Department of Agriculture (DA) and their link agencies assist for the
training and seminar on farm machines operation.
Testing
All farm machineries are under the QC of PhilMech.

7. MODERN RICE TECHNOLOGY
ADONES S. CAINGLES
• Heterosis is the superiority of F1 offspring over either parent, a solitary means of
harnessing complete hybrid vigor in crop plants.
• Hybrid rice technology has substantial yielding ability that is able to enhance farm
productivity 15–25% than inbred varieties.

• Low Price
• Relatively high in production cost
• Drying Problem

9. FACTORS IN LIMITING INCREASE IN RICE PRODUCTION
ADONES S. CAINGLES
• Lack of resistant varieties
• Nutrients imbalance
• High cost of farm inputs
• Deprive from modern technologies
• Lack of education in rice farming community
• Abiotic factors and Biotic factors
• Poor in road accessibility and infrastructure
• No farmers Organization
