Abstarct: In order to study the effect of sugar beet molasses on the growth and yield of chickpeas at different irrigation intervals, an experiment was conducted in Research Farm of Shahroud University of Technology in 2018-2019. The experiment was as split-plot factorial baxsed on a randomized complete block design with 3 replications. Factors were 2 irrigation intervals (8- and 16-day intervals), foliar application of 3 molasses levels [control (spraying of water), 50 and 100 L.ha-1] and soil application of 3 molasses levels [control (zero), 50 and 100 L.ha-1]. The results indicated that all traits were affected by some sources of variations presented in ANOVA table. At the 16-day irrigation interval, the grain yield was 19% lower as compared to the 8-day irrigation interval. Accordingly, chickpea has faced shallow drought stress. With increasing the amount of molasses application on the soil, the SPAD value, relative water content, proline, leaf soluble sugars, and 100-seed weight have proportionally increased. Simultaneous application of molasses on the soil and leaf promoted grain yield to a level higher than control. Simultaneous application of 50 L.ha-1 molasses on the soil and leaf was the best treatment combination.
