M-101' rice was released in 1979 by the California Cooperative Rice Research Foundation and the USDA, but despite this long-season pedigree, it's actually a versatile variety suitable for climates as far north as New England. It can be grown as either an upland (dryland) rice, or a paddy (irrigated) rice, and has medium-sized grains. Considered semi-dwarf, the plants can grow to nearly three feet tall. It requires more nitrogen than most heirloom varieties, and is considered vigorous and productive. Plants are resistant to lodging (the technical term for falling over). Ripens in approximately 120 days.

Our seed was grown by Professor James Tuten of Juniata College in central Pennsylvania. Professor Tuten is a noted expert in Atlantic rice culture, and author of the book Lowcountry Time and Tide: The Fall of the Rice Kingdom.


April 15

Soak rice seed in small containers in at least 1⁄2 inch of water to cover. Monitor and refresh the water as needed every couple of days. The rice will take from 5 to 10 days to germinate. You will see a tiny white sprout at one end of the seed. This is not the root, but will develop into the first green leaf. The root will appear later at the same end of the seed, but opposite the leaf shoot, and will be a thin white thread. You can transplant when the first leaf shoot is about 1/4 inch long, you do not need to wait for the radicle to appear, just make sure you plant with the shoot side up.

Third Week in April

Pot up the sprouted seeds at the two-leaf stage, using regular organic potting mix, into individual cells. These do not need to be large, 9-packs work well. If you are growing a dryland variety, keep the soil moist but do not saturate it.

After all Danger of Frost

Transplant directly out into the garden in well-worked, moderately fertile soil. In my garden this is around the first week in June. I generally plant about 8 to 10 inches apart in all directions. Keep the soil mulched and evenly moist, at least until the plants are established. Saturate the soil during panicle primordia, or the period of time when the panicle is forming inside the stem. Cold nights during flowering will lead to blank spikelets. The variety Loto produced very well even with no special attention or irrigation during the 2016 summer drought.


First harvest of 'Loto' will be around the second week in September. Ideally, harvest the rice when at least 2/3 of the grains on each stem have dried down and turned an even beige color. This is not always possible since birds and chipmunks are attracted to rice. Also, rice plants will not survive frost. If necessary, harvest when grains are still faintly green. If you need to do this, be sure to do a germination test of the greenest kernels so you can identify any unviable grain.


Threshing is simple and just involves removing the mature grains from their stems. There are foot-powered peddle threshers on the market. Milling is more complicated (removing the hull from each grain) and requires special equipment. Ideally, milling occurs right before consumption.
