Then, there are three types of rice

Then, there are three types of rice cropping systems followed: single-cropped rice,
double-cropped rice, triple-cropped rice. Single-cropped rice used 160-180 days (long-term rice varieties) was
often planted under predominantly rain-fed conditions in the lower Mekong Basin (Northeast of Thailand),
whilst types of double and triple-cropped rice used short-term varieties (90-100 days) and mainly
concentrated in the lower CPRB of the country, because of received irrigation water around the year [5], [9].
