Description In order to develop simple and adaptable measures to reduce the impact of changing climatic con ditions and poor postharvest practices on grain quality, data on temperature and postharvest
practices were collected and correlated with physical grain quality parameters for 3 rice devel opment hubs (Ndop, Lagdo and Mbam) in Cameroon. Inter-annual variations in temperature and
thermal amplitudes were the highest in Ndop followed by Mbam and the least in Lagdo. When the
same rice variety was grown in the hubs and milled with a laboratory hand dehusker, the mean
chalky score was highest in Ndop (18%) and least in Mbam (11%). In addition, Ndop recorded
higher grain fissures and broken fractions compared to Mbam or Lagdo. Positive correlations
were observed between thermal amplitudes, grain fissures and the proportion of broken fractions.
However, rice milled using commercial mills located in the hubs recorded the highest broken frac tions in Mbam (54% - 63%), followed by Lagdo (43% - 52%) and the least in Ndop (35% - 38%). The
type of mills in the hubs was responsible for these differences as Mbam had only Engelberg types
mills that recorded higher broken fractions than in Ndop where only rubber roll mills were
present (P < 0.05). Lagdo had a mixture of Engelberg and rubber roll mills and recorded interme diate broken fractions. Proper parboiling, recovery and processing of poorly filled and immature
grains during parboiling and processing of low-grade and fine broken rice into product generally
accepted by the local population were demonstrated as simple adaptation strategies to mitigatethe adverse effects of changing climatic conditions and poor postharvest practices on the physical
quality of rice especially in sub-Saharan African countries.
