EFFECT OF SUPPLEMENTARY IRRIGATION AND FOLIAR APPLICATION OF ZINC SULFATE ON SEED YIELD AND ITS COMPONENTS OF CHICKPEA IN ARAK, IRAN

To consider supplementary irrigation and application of different level of Zinc sulfate on yield and yield components and some physiological traits of chickpea c.v. "Hashem", this research was This study carried out in a split plot experiment based on randomized complete block design with four replications at the Research Farm of the Islamic Azad University of Arak.. Treatments applied consisted of two levels (supplementary irrigation and rain-fed condition) and three rates of the foliar zinc sulfate application (12, 24 and 36 grams). Results showed that the effects of supplementary irrigation and foliar application of fertilize grams/liter on seed yield and biological yield were significant at 1% level of probability. Highest seed yield (567.2 kg/ha) was obtained from applying supplementary irrigation.
