Abstract Rice is a staple food for more than 50% of the world population, therefore a sustainable sufficient rice production is a key strategic issue to ensure their food security. In line with this issue, many studies have been and are being carried out to improve the rice production. In this report, we describe the results of our study to apply a sustainable and clean technology to increase the total grain weight per plant of rice variety of MR 219. In this study, a 2-D clinostat was utilised to treat the rice seeds (variety MR 219) to enhance its total grain weight per plant. A 2 3 full factorial design was employed to investigate the effects of three different factors (rotation period, rotation speed and distance of the seeds from the center of clinostat) on the total grain weight per plant. The treated seeds were planted in an open area and the total grain weight per plant was measured after harvesting the plants. Analysis of variance, the F-test and the Student’s t-test at 95% of confidence level shows that the distance of seeds from the center of clinostat affects the total grain weight per plant significantly. © 2019 Elsevier Ltd.
