This research aims to study the effect of planting dates on the variation of some important agronomic characteristics of photoperiod sensitive cultivars. The experiment was conducted at Nakorn Ratchasima Rice Research Centre during wet season 2011-2013 by using a split plot in RCB design with 3 replicates. Main plots consisted of 5 planting dates; May 5, June 5, July 5, August 5, and September 5. Sub plots consisted of 4 photoperiod sensitive rice cultivars; i.e. KDML105, RD45, RD6, and RD12. Some important agronomic characteristics were recorded. Data sets from each year were analyzed using a single site analysis. Treatment means were compared using a Duncan's Multiple Range Test (DMRT). The results showed that planting dates significantly affected some...

Study on effect of environment on four rice planting durations (January, April, July and October) and four rice varieties (PTT1, PSL2, RD31 and RD41) was conducted at Ratchaburi Rice Research Center in 2011. The experimental design was split plot in RCB with three replications. Varietal characteristics, yield, yield component and meteorological data were recorded. PTT1 variety showed the longest maturity (128 days). Rice planting in April showed higher yield (808 kg/rai) than that planting in other durations. In addition, planting in April also showed the highest panicle length, number of filled seeds/panicle and 1,000 seed weight. The longest harvesting period (123 days) and lowest yield (510 kg/rai) was found in October planting. This could be...

Effect of climate change on rice growth and yield had been studied during January 2011 through October 2013 at Chiang mai Rice Research Center, Chiang mai Province. Experimental design was split plot with three replications. Main plot were planting dates in each month as planting at January (stage1) April (stage2) July (stage3) and October (stage4). Sub plots were rice varieties, consisting of Plathumtani 1, Phitsanulok 2, RD31 and RD41. The research found that the climate change under stress of environmental. Effect to the rice varieties as a permanent. Planting in January in 2011, temperature in the night less than 15 degree and between the day temperature more than 30 degree effect to plant height of Plathumtani 1 and effect to germination of rice seed....

Research was conducted in order to study the environmental effects on characteristic variation in the photoperiod sensitive rice varieties at Nakhon Si Thammarat Rice Research Center during 2011-2013. Rice varieties in the study were included Pathum Thani 1, Phitsanulok 2, RD31 and RD41. Results showed that rice grown in April having plant height, number of tillers per hill, number of panicles per hill and panicle length more than rice grown in January and July. The number of filled grains and yields were highest when grew in January. Rice grown in April had high percentage of unfilled grains. The influence of other climatic conditions did not show obviously effect on the growth of rice varieties in the study.
