Strategic agronomic options for a sustainable lowland rice farming system in northwest Cambodia

Abstract

The use of remote sensing for rice phenotyping is a current trend in research, providing spatial and temporal information that depict the ecosystem dynamics in a changing environment. A good agronomic option is one of the key factors required to enhance food security, mainly where poor agronomic practices are prevalent. Seed broadcasting, weeds, low fertilizer input and wrong fertilizer timing are the major agronomic problems identified in northwest Cambodia that contribute to low rice yields. Hence, this research will use some spectral reflectance technologies to monitor rice growth, biomass, guide our decisions on fertilizer applications and collect information required for sustainable rice production.
