Evaluation of growth and physiological traits in some peanut promising lines in response to two cretaceous (conventional) and furrow (ridge) irrigation methods

In order to determine the best irrigation method to improve growth and physiological traits of some promising peanut (Arachis hypogea L.) lines in Guilan province, two experiments carried out in 2017 - 2018 cropping seasons as split plot based on randomized complete block design with three replications in Rasht, Iran. Two irrigation methods including of cretaceous (conventional) and furrow (ridge) methods and five promising peanut lines ( 128, 176, 192, 201 and 208) comprised experimental treatments as main and sub plots, respectively. Results showed that cretaceous irrigation method caused to increase pod numbers per plant (26.46). In this experiment, peanut 192 line produced the greatest seed yield (3128 kg/ha), seed unmber per pod (2.08) and biological yield (8983 kg/ha) in response to cretaceous irrigation method. In addition, the greatest seed oil content (52.94 %) was obtained under conventional cretaceous irrigation method. In general, results showed that the cretaceous (conventional) irrigation method of peanut enhanced seed numbers per pod, seed yield and biological yield of peanut promising lines under region climatic condition.
