Abstract

Field experiment was carried out in Babylon / AL-Musseib during (2017)  season to study the effect of leaves spraying with Multiple ABA concentrations on some characters of vegetative growth and yield of Lashata cotton cultivar under the effect of water stress.

Randomized Complete Block Design was used with three replicates according to split plot arrangement. The study included four irrigation periods ( 10,15, 20, 25 days) between each irrigation time ( Main Plots ) while ABA spray concentrations (0,40,80,120) μM occupy the ( Sub plots ). The results showed presence of significant differences in studied characters with ABA spray, So 80 μM of ABA predominate and gave the highest plant height 93.07 cm and vegetative branches number 4.12 branches.plant-1, total boll number 13.35 bolls. Plant-1 , seed cotton yield 34.02 gm. Plant-1, also there is significant differences among irrigation periods, as irrigation treatment each 10 days gave the highest average plant height 91.54 cm , number of sympodial branches 12.77 branch.plant-1 , number of open bolls 12.74 bolls . plant-1, seed number per bolls 24.95 seed.bolls-1 and seed cotton yield 33.75 gm.plant-1. Interaction between irrigation periods and ABA spray concentration had a significant effect on the studied characters whereas irrigation treatment of every 10 days with ABA sprays of 80 micromole concentration.
