The experiment was conducted during the agricultural season (2016-2017) to study the effect of paper spraying with Abyssic acid and mixing polymers with soil to grow the Abelmoschus esculentusunder different irrigation periods. The experiment developed with the design of complete random sections as a global experiment with three replicates. The first factor included irrigating factors (irrigations 3, 6, 9) day and spray agent with Abyssic acid at concentrations (0, 3, 6) mg / L and the third agent mixing polymers with soil, Soil mixed with polymers (0.5 kg / m2) with a depth of 20 cm. The results showed that the increase in the duration of the irrigation period to 9 days resulted in a decrease in the characteristics of the study (dry weight, chlorophyll content, relative water content in leaves) and a clear increase in the percentage of water deficit in the soil while irrigation every 3 days significantly exceeded the studied traits. The results showed that spraying plants with Abyssic acid and its different concentrations, especially 6 mg / L, led to a clear increase in the traits studied. Mixing the soil with polymers has led to a marked improvement in the studied indicators and increased plant resistance to water scarcity. Interaction factors between the duration of irrigation with alfalfa and the addition of soil polymers showed a significant effect on most studied traits.
