Inadequate N Application of Rice Farmers in the Philippines Problems, Causes, Solutions

Inadequate application of nitrogen (N) fertilizer has been identified by the Food Staples Sufficiency Program (FSSP) as a major constraint in achieving rice self-sufficiency. The available literature on fertilizer application in the Philippines tends to find inadequate N application under the agronomic and economic criteria. Explanations for the gap may be grouped under the following sets of factors: external constraints; attitude towards risk; and internal constraints. Different explanations imply different policy solutions, hence it is critical to correctly identify the most relevant explanations. A new estimation using FAO Fertibase data confirms the finding of inadequate N application by rice farmers in the Philippines. Additional study is proposed covering the following: a) comparing actual to optimal N application using secondary data for Central Luzon (obtained from the International Rice Research Institute); b) identifying the reasons for inadequate N application using primary data collected from a survey of rice farmers in Nueva Ecija.
