This manual outlines the complete rice production cycle, beginning with the use of a crop calendar to plan field operations and ending with market‑related advice. It details each major step—variety choice, seed quality, land preparation, planting, weed control, fertilization, irrigation, pest management, harvest timing, safe storage, and efficient milling.
In addition to practical field instructions, the guide provides technical information on milling parameters, grain quality characteristics, and chemical properties such as amylose content and gelatinization temperature, helping farmers produce high‑quality rice that meets market standards.
| Recommended moisture content for milling | 13–14% |
|---|---|
| Maximum grain temperature during milling | 45 °C |
| Amylose content range | 15–35% |
Rice should be milled when its moisture content is between 13 % and 14 %.
Grain temperature should stay below 45 °C while milling.
Rice amylose content normally ranges from 15 % to 35 %.
Short‑duration varieties mature in less than 120 days from planting to harvest.
