Tulshimala is a photoperiod-sensitive Aman variety of rice. It is planted from the last week of July to the first week of August. Flowers bloom from the end of October to mid-November. Harvesting takes place from the first to the last week of December (mid-Ogrohayon to early Poush).[1] Without a plant protection measure, the yield is 2.50 to 2.75 metric tons per hectare, and with plant protection measures, the yield is 3.00 to 3.25 metric tons per hectare. The maturity period is 125-140 days (depending on the variety and yield). The rice is dark gray in color. The average weight of 1000 grains is 11 grams (dry grain).[2] On April 11, 2018, the Sherpur District Administration filed an application for Geographical Indication (GI) registration of Tulashimala rice with the Department of Patents, Designs, and Trademarks (DPDT). After completing all the necessary procedures, Tulashimala rice from Sherpur was registered as the 14th Geographical Indication product in the country on June 12, 2023.[3][4]
