Cultivation Techniques for Increasing Rice Productivity in Myanmar

To improve rice productivity in Myanmar, we evaluated two Korean rice cultivars and one Myanmar rice cultivar comprised of planting density and fertilization amount in three experiments from rainy season 2014 to dry and rainy season 2015. In the planting density experiment during wet season 2014, the rice yield in Yeongpoong and Shwethweyin cultivars increased considerably under high planting density but there was no significant differences in rice yield of Dasan 2 cultivar between planting density treatment. In dry season cultivation 2015, rice yield increased considerably under high planting density at all experimental cultivars. In wet season cultivation 2015, the rice yield of Dasan 2 and Yeongpoong cultivars was significantly increased except Shwethweyin cultivar. The yield of Dasan 2 cultivar was high in rainy season but there was much variation in yield among the planting density treatment and cultivation years. The yield of Yeongpoong cultivar was higher in wet season cultivation than dry season cultivation and significantly increased with planting density. In the fertilization amount experiment, the yield of Dasan 2 cultivar cultivated in wet season 2014 was increased considerably with increasing fertilization amount but there was no difference between Yeongpoong and Shwethweyin cultivar. The yield of Yeongpoong cultivar cultivated in dry and wet season 2015 was increased significantly with increasing fertilization amount. The Myanmar rice cultivar Shwethweyin was no difference in yield with increasing fertilization amount. The yield of Korea cultivars Dasan 2 and Yeongpoong was increased significantly with increasing fertilization amount but there was some yearly and seasonal variation. From the above results, if cultivation techniques would be applied in Myanmar, it is possible to raise productivity by using Korean rice cultivars.
