Early cultivation - Soukisaibai

Japanese: 早期栽培 - そうきさいばい

A cultivation method mainly seen in Japan's paddy rice cultivation, in which seeds are sown one to two months earlier than normal cultivation, shifting the growing season forward. Although it varies by region, seeds are sown from mid-to-late March to early April, and harvesting takes place in mid-August or at the latest early September. It began in the mid-1950s and spread mainly in warm areas of southwestern Japan, and is also widely practiced in Chiba Prefecture in the Kanto region. The varieties used are different from those used in normal cultivation in each region, and varieties from the Tohoku region that produce ears earlier are used.

Japanese:

主として日本の水稲作にみられる栽培法の一つで，普通期の栽培と比較して1～2ヵ月早く播種し，作期を早めにずらせるものをいう。地域によって差はあるが，播種は3月中･下旬から4月上旬にかけて行い，8月中かおそくも9月上旬には収穫に至る。1950年代の半ばころに始まって西南日本の暖地を中心に普及し，関東地方でも千葉県で広く実施されている。使用される品種はそれぞれの地域の普通期栽培のものとは異なり，穂が早く出る東北地方の品種が用いられる。
