Type: article
Abstract: To study the effects of planting date and plant density on Amaranth, two field experiments were conducted in 2013 at Marv-Dasht, Fars, Iran. The field experiments were conducted as split plot in a randomized complete block design with 3 replications. Plant density (6.6, 8.3 and 11.0 Plant.m -2 ) and planting date (June 22 ed , July 6 th and July 21 st ) were used as treatments. Results of this study revealed that the planting date and plant density had significant effect on number of leaf per plant, stem diameter, leaf dry weigh, stem dry weight, forage yield, relative growth rate (RGR), crop growth rate (CGR) and leaf area index (LAI). Highest amaranth forage yield (11.7t.ha -1 ) was obtained from 6.6 plant.m -2 density and July 6 th planting date. Moreover, in the experiment condition the amaranth yield was also reduced with delay in planting date from 6 th to 21 st July and increases the plant density from 6.6 to 11 plant .m -2 significantly.
