| The effect of climate change on rice growth and yield had been studied during December, 2010 through March, 2012 at Chiang Rai Rice Research Center, Chiang Rai Province. Experimental design was split plot with three replications. Main plots were planting dates which designed to plant at monthly interval. Sub plots were rice varieties, consisting of Suphan Buri 1 (SPR1), and Suphan Buri 2 (SPR2). Planting method was pre-germinated seed broadcasting with seed rate of 15 kg/rai. The research found that planting in July was appropriate for both SPR1 and SPR2 variety in term of growth, growth duration and yield. Averaged plant heights were 136.4 and 122.3 cm with of SPR1 and SPR2 variety, respectively. The average yields were 827, and 678 kg/rai for SPR1 and... |
