What is Paddy Rough (Rice) Specification?

In addition to achieving self-sufficiency in rice production, the production of good quality rice is very important. In order to achieve this, the Standard Organization of Nigeria (SON) developed the Paddy (Rough) Rice Specification for stakeholders such as farmers, millers and traders for the determination of paddy rice quality. Another objective for the development of the specification was for the harmonisation of existing paddy rice testing methods utilised by various integrated rice mills.Rough rice may be graded into three grades on the basis of the tolerable limits established (refer to table below).

How to Check Paddy Quality | Workflow Documentation

Paddy quality can be checked using the methods described in the paddy grading and paddy quality checking manuals. Since Paddy Grading can be conducted only in the grading laboratories of mills with a set of equipment, the Paddy quality checking method was developed for farmers, extension agent and buying agents to check their paddy with a set of less expensive equipment, so that they can verify the grade prescribed by mills. Farmers can also conduct the simple checking for finding out what they have to do, in order to improve their cultivation and/or post-harvest activities. Manuals on paddy grading and paddy quality checking are shown here. The procedure for paddy grading is shown below.
