A sustainable and green approach was applied to treat rice (MR 219) in order to improve the rice yield (1000-grain weight) using a 2-D clinostat. A 23 full factorial experimental design technique was used to investigate the effects of distances of rice seeds from the center of clinostat (1.5 and 2.5 cm) rotation speeds (2 and 10 rpm) and rotation periods (5 and 10 days) on 1000-grain weight of rice (variety of MR 219) at two levels (low and high). The results were analyzed using Students t-test analysis of variance and F-test by Minitab software to determine the significant factors that affected the yield. Main effects and interaction effects of the factors were also analyzed statistically. The most significant variable was found to be the distance of rice seeds from the center of clinostat followed by two interaction effects of rotation period and distance of rice seeds from the center of clinostat. Higher rice yield (28.9601 g of 1000-grain weight) was achieved by the rice seeds treated with the clinorotation compared to that of control (23.0600 g).

Abstract

A sustainable and green approach was applied to treat rice (MR 219) in order to improve the rice yield (1000-grain weight) using a 2-D clinostat. A 23 full factorial experimental design technique was used to investigate the effects of distances of rice seeds from the center of clinostat (1.5 and 2.5 cm) rotation speeds (2 and 10 rpm) and rotation periods (5 and 10 days) on 1000-grain weight of rice (variety of MR 219) at two levels (low and high). The results were analyzed using Students t-test analysis of variance and F-test by Minitab software to determine the significant factors that affected the yield. Main effects and interaction effects of the factors were also analyzed statistically. The most significant variable was found to be the distance of rice seeds from the center of clinostat followed by two interaction effects of rotation period and distance of rice seeds from the center of clinostat. Higher rice yield (28.9601 g of 1000-grain weight) was achieved by the rice seeds treated with the clinorotation compared to that of control (23.0600 g).
