Abstract

In order to study of effects different amounts of NITROGEN FERTILIZER and PLANT SPACINGs on RICE agronomical characteristics (line 216), an experiment in split format based on randomized complete block design (RCBD) with four replication in RICE Research Institute of Iran, Rasht, in 2000 was conducted. In this experiment main factor included four nitrogen levels (n1= 75 kg/ha, n2= 100 kg/ha, n3=125 kg/ha and n4=150 kg/ha) and sub factor included three PLANT SPACINGs (a1= 15×15 cm, a2= 20×20 cm and a3= 25×25 cm). the studied traits consist of grain YIELD, straw YIELD, plant height, 1000 grain weight, number of grains in main and sub panicle, number of bearer and non-bearer tillers, percentage of unfilled grains, length of main and sub panicle and harvest index. The effects of nitrogen levels and PLANT SPACING and also these interaction effects in more studied traits showed a significant difference in 1 % probability level. The highest grain YIELD was obtained by 100 kg/ha nitrogen with 4542 kg/ha. The PLANT SPACING of 20×20 cm with 4206 kg/ha was recorded the maximum grain YIELD.
