Abstract

With the purpose of determining critical time of weed control under conventional and ultra-narrow row spacing conditions of cotton (Gossypium hirsutum L. ) (Khordad cultivar), a field experiment has been conducted as a factorial arrangement in a randomized complete block design with three replications in Sabzevar during the water year of 2015. The studied factors include the conventional cultivation system (70-cm row spacing), ultra-narrow row (20-cm row spacing), and duration of weed interference (0, 30, 45, 60, and 7 days after emergence and during the full season). Results from the experiment show that in ultra-narrow row condition, seed cotton yield losses of 2. 5%, 5%, and 10% are estimated to occur 27. 4, 36. 1, and 44. 7 days after emergence, respectively. Also, under the conventional condition, yield losses of 2. 5%, 5%, and 10% are estimated to occur 8. 1, 13. 5, and 24. 4 days after emergence, respectively. It is proven that the onset of seed cotton yields on lint yield loss occurs earlier (i. e., 46. 3 and 53. 7 days after emergence, respectively) under conventional condition, while under ultra-narrow row condition the onset of seed cotton yield and lint yield loss is postponed to 57. 9 and 65. 9 days after emergence, respectively. Overall, the experiment results show that cotton cultivation in ultra-narrow row spacing under weed interference conditions could provide a better seed cotton yield than conventional spacing.
