Abstract

Plant density is one of the important factors to be considered in crop management decisions to obtain high YIELD with optimum quality. In order to determine plant density effect on different RICE cultivars an experiment was conducted in Tonekabon RICE Research Station in 2008. This experiment laid out as split plot in a randomized complete block design with 3 replications. The main plots were planting spaces with four levels (12, 14, 16 and 18 cm) and sub plots were RICE cultivars (Shiroodi, Kados, Hashemi and Deylamani). Distance between rows was 30 cm in all treatments. ANOVA did not show significant differences for all characters (except filled and total grains) measured. Effect of cultivars on fertile florets and total grains was significant at 0.05 and on the other traits at 0.01 probability level. The highest grain YIELD 5787 kg.ha-1 was obtained at 18 cm PLANT SPACING. The greatest grain YIELD 7374 kg.ha-1 was recorded for Shiroodi cultivar. Results showed LAI were greater at 12 cm PLANT SPACING and CGR, RGR greater at 18 cm PLANT SPACING and Shiroodi cultivar. Finally, according to the results, 18 cm PLANT SPACING and Shiroodi cultivar can be recommended to the experimental area.
