The milling methods used in most of Asia remain fairly primitive, but massive mills function in Japan and another areas.
Some large mills, handling 500 to 1,000 tons of paddy day by day, have specialised hulling plants with consequent smaller losses from damaged grain. When reaper binders are used, the crop is "shocked" in certain ways so that the grain is protected from rain. Improvements are slowly going down. When combine harvesters or binder threshers are employed, the grain must be dried to about 14 % moisture in order that no deterioration takes place in storage. Oryza sativa), edible starchy cereal grain and the grass plant (household Poaceae) by which it's produced.

Rice yields range considerably, starting from 700 to 4,000 kilograms per hectare (600 to 3,500 pounds per acre). Basmati rice has a tender, fluffy texture and a mild, nutty taste with versatile culinary uses. Compared to other rice merchandise, Arborio has a chewier and creamier texture. The rice works well blended into a dish or as a facet dish. It is eaten alone and in an ideal number of soups, aspect dishes, and principal dishes in Asian, Middle Eastern, and lots of other cuisines.

Adequate irrigation, which means inundation of the fields to a depth of a number of inches through the greater a part of the growing season, is a basic requirement for productive land use. The seeds are sown in prepared beds, and when the seedlings are 25 to 50 days outdated, they are transplanted to a subject, or paddy, that has been enclosed by levees and submerged underneath 5 to 10 cm (2 to 4 inches) of water, remaining submerged in the course of the growing season.
