Abstract

In order to evaluate the effects of PLANT DENSITY on MORPHOLOGICAL CHARACTERISTICS and YIELD of COTTON, this experiment was conducted by using a factorial design, based on randomized complete block, with two varieties (Varamin and B-557), five plant densities (5, 10, 15, 20 and 25 plants per square meter) and four replicates in the COTTON Research Center of Varamin during 2000 growing season.With the exception of plant height, internode length and dry weight of single boil, B-557, was surperior in other characters, as compared with cultivar Varamin. Although there was not significant differences between varieties with regard to number of vegetative branches per plant, per unit area and YIELD, it is better to use higher plant population of B-557 which has close growth, because in this condition the growth of these varieties will not be limited as compared with Varamin which has open growth. Increasing PLANT DENSITY, decreased height of plants. The significant effect of plant population on the number of nodes and its nonsignificant effect on internode length suggest that reduction in the number of nodes per plant influenced plant height.Although higher plant densies reduced number of vegetative and reproductive branches per plant, number of bolls per heactare1dry weight of single boil, dry weight of bolls per plant and dry weight of single plant, YIELD, per hectares due to higher plant number per unit area, was increased. In spite of nonsignificant differences between 15, 20 and 25 plant populations, highest YIELD gain was obtained when 25 plants per m2 were used. Number of bolls per plant and per m2, dry weight of bolls per plant, dry weight of single plant and dry weight of plants per m2 were inf1uenced by variety and PLANT DENSITY interaction.
