Zhe 733 Lowland Rice

NEW for 2020     “Early Maturing Long Grain”

Zhe 733 is extremely early maturing for a long grain rice. It was developed in Zhejiang Sheng China. It is a modern lowland cultivar and was chosen, based on its earliness, for inclusion in my 2019 rice trials wherein early maturing lowland varieties were grown in upland conditions. I can clearly state that this variety does not perform well under upland conditions. At least not without some adaptation. It will require significant more water than the usual rainfed conditions of most upland varieties. I obtained my initial seed from the USDA.

Zhe 733 flowered 57 days from transplanting and was harvested 99 days from transplanting. It is considered a semi-dwarf variety and reached a height of 3 1/2 foot tall. It had no lodging issues during periods of heavy rainfall yet the USDA states that it is susceptible to lodging. Possibly growing it as an upland type gives it a more stable root system. The low yields were mostly due to the fact that the plants had few grain bearing tillers. In a lowland paddy system I would expect that it would tiller much more and have good yields. I will be offering this variety in 4 gram packets.

Rice seeds should be soaked in water 24 hours before planting. I start my plants indoors in April in plug flats, 50’s and transplant into beds after the last frost date. I recommend not leaving plants in flats for more than three weeks as the starts will yellow easily and weaken when root-bound. Here in Northern Indiana, I plant my rice plugs the last week of May. I plant into 4′ wide beds. This makes adding bird netting over the tops of the plants an easy chore using 5′ t-posts and twine. The plants are spaced 9″ apart in the beds. Upland rice requires about the same amount of water as corn, around 1″ per week during the growing season.  I harvest by cutting the whole plant and bundling into groups of 4. These bundles are then hung in my drying shed for a few weeks until the plant is fully dry. At this point threshing is easy by hand (pulling the grains off) or using a threshing machine. I use a treadle (foot) powered thresher. Rice has an inedible husk that needs to be removed before eating.   The most primitive way to accomplish this is by pounding the grains with a stick or mallet on a wood surface (tree stump) in order to loosen the husks. There are small rice dehullers available but very difficult to locate. Brill Engineering offers online tutorials on how to build a small dehuller using easy to locate “off the shelf” parts.  http://www.brillengineering.com/


  • Alternative planting method. In the spring of 2017 I experimented with direct seeding rice into beds in late May. I had success with early maturing varieties. I recently learned that rice can be direct seeded even earlier; possibly at the beginning of May or late April. I would suggest you conduct some small trials if you are interested in this method. Weed management is critical early on for young rice seedlings!
