Rice Sowing Dates

Oryza sativa L.

Optimal rice sowing dates are determined by the crop's temperature requirements and the flooding schedule of the basins required for weed control and soil warming.

In the reference 28 varieties crop Rice, where this is mentioned in the description.

The minimum temperature for rice seed germination is +10…+12 °С, while normal growth and development require +20…+25 °С. It is critical to note that a temperature drop to +12…+14 °С during the flowering stage triggers spikelet sterility and empty grains; therefore, sowing dates serve as the primary risk management tool.

Technologically, rice sowing is inextricably linked to the schedule for filling basins with water, as the water layer serves not only as a source of moisture but also as a means of weed suppression and thermal regime regulation. In the case of the seedling method, sowing in nurseries allows for the effective distribution of heat resources during the growing season, shifting transplanting dates into the basins depending on the biological characteristics of the variety.
