Abstract

In order to study the effects of starting and ending the IRRIGATION timing on the growth of different COTTON cultivars in Varamin region, a research experiment was carried out in COTTON field on the planting year of 2003. The experiment was carried out in the farm of factional statistics on the basis of completely randomized block design with Varamin cultivars, Sindouse and 818-312 (factor A) and with 3 starting IRRIGATION timing for the FIRST ACTUAL LEAVES, with 6-8 LEAVES and FIRST SQUARE (factor B) and with ending IRRIGATION timing about 5% of boils have attained their final size, about 10%of boils have attained their final size, about 30 % of boils have attained their final size (factor C) with three repetition in 108block, each block consist of 4 implant line with the length of 10meter in which two first and last line were margin and all the studies and note makings were done from the middle line often cutting out 0.5 meter from the beginning and ending part of each line. The whole experiment was done in the field area of approximately 3900 m2. The maximum height of COTTON bush was non significant but in Varamin cultivar and in starting IRRIGATION timing of 6-8 LEAVES and ending IRRIGATION when 10% of COTTON boils were to the final size. The maximum number of flowers in the bush was in Sindouse cultivar in starting IRRIGATION timing of the FIRST ACTUAL LEAVES and ending IRRIGATION when 30 % of boils were to the final size with the average of 67. 51 flowers in the bush and was significant at 5%. The maximum number of middle node in bush was found in Sindouse with the starting IRRIGATION timing of the FIRST ACTUAL LEAVES and ending IRRIGATION when 20 % of COTTON boils were to the final size with the average of 13. 67 middle nodes in bush and was significant at 5%. Between 818-312 cultivar. with yield of 3176 kg/ha and Sindouse cultivar with yield of 3091 kg/ha was non significant and in Varamin cultivar was obtained minimum yield with 2827 kg/ha, attention to significant of interactive effects between cultivars, starting and ending the IRRIGATION timing, Sindouse cultivar in starting IRRIGATION timing of the FIRST SQUARE and ending IRRIGATION when 30 % of boils were to the final size with the yield average of 4227 kg/ha was found to be the best treatment combination.
