Effects of Planting on Growth and Yield of Rice

Effects of various planting methods on the growth and yield of rice were studied in a comparison experiment on small lots. It was found that the rice cultivation using the widenarrow rows with evenly staggered planting populations and beds, which resulted in a high planting density of 270 000 plants·hm^-2, substantially enhanced the grain development, lifespan of functional leaves, leaf area index, growth period, photosynthesis, chlorophyll content, output coefficient of light energy, as well as panicle and grain counts on the rice with a yield of 11 711.11 kg·hm^-2, which was 5.75% increase over the widenarrow rows, or 15.03% over the wide rows and narrow beds.
