Title: Effect of Plant Density on Yield and Yield Components of Rice
Abstract: for study of plant density on yield and yield components of rice variety Hashemi, an experiment in factorial format based on randomized complete block design with 3 replications, at a paddy field in Lahijan Township (north of Iran) in 2009 was conduced. Factors of Experiment was consist of three levels of plant spacing (a : 15×15, a : 20×20 and a : 25×25 cm) and three levels of number of seedling per hill (b : 1, b : 3 and 1 2 3 12 b : 5 seedlings per hill). Results showed that, the effect of plant spacing and also number of seedling per hill 3 on all studied traits was significant in 1% probability level. Highest grain yield among plant spacing levels was found from 15×15 cm treatment with 3415 kg/ha. Also, between number of seedling per hill, b treatment with 2 3526 kg/ha grain yield was recorded the highest amount of this trait. Interaction effect of plant spacing and number of seedling per hill on grain yield, straw yield and harvest index was significant in 1% and on biological yield in 5% probability level. Also, on other traits was non significant. The interaction level of a b with 3612 22 kg/ha was recorded the highest grain yield.
