Title

EFFECT OF PLANTING DATE AND PLANT DENSITY ON MORPHOLOGICAL CHARACTERISTICS OF COTTON (GOSSYPIUM HIRSUTUM CV. SIOKRA)

Pages

  25-38

Abstract

 Delay in sowing, and increasing PLANT DENSITY in order to compensate yield lose resulted from delayed sowings, induce some changes in MORPHOLOGICAL CHARACTERISTICS of COTTON such as main stem height, main stem node number, and monopodial and sympodial branche number and length. Thus, in order to investigate the effects of PLANTING DATEs and PLANT DENSITY on MORPHOLOGICAL CHARACTERISTICS of COTTON, an experiment was conducted using Siokra cultivar in 2002 at COTTON Research Station of -Karkandeh, Kordkoy. The experiment was carried out as a split - split plot in a randomized complete block design with four replications. Three PLANTING DATEs (May 15, May 31 and June 22) considered as main plots, and two row spacings (60 and 80 centimeters) and three plant distances (10, 20 and 30 centimeters) considered as sub- and sub- sub- plots, respectively. The results showed that delaying in sowing date decreased monopodial branche number and plant height, and increased length of the highest monopodial branche, the number of sympodial branche and main stem node. However, the influence of sowing date on the length of sympodial branches was not significant. In all three PLANTING DATEs, an increase in PLANT DENSITY accompanied with decrease in monopodial and sympodial branche number per plant, length of the highest monopodial branche, sympodial branche length, and main stem node number, whereas main stem height increased to some extent. Among MORPHOLOGICAL CHARACTERISTICS of COTTON, main stem node number (in normal PLANTING DATE), and length of the highest monopodial branche (in other PLANTING DATEs), showed the most sensivity to increasing in PLANT DENSITY.
