Abstract

Background

Identification and development of new varieties are important elements of improving and sustaining soybean yield, especially in arid and semi-arid regions, including Iran.

Methods

The study aims to investigate the effect of different levels of low irrigation on yield and qualitative characteristics of different soybean cultivars (Dezful 504, Sahar, Telar, Tekavar, Zan and Sari) under water stress (90%, 70% and 50% of the field capacity), under the climatic conditions of Jiroft during two years (2020 and 2021). This experiment was carried out as a split plot based on a randomized complete block design with 18 treatments and 3 replications at the farm of South Kerman Agricultural Research and Training Center and Natural Resources.

Result

The highest qualitative characteristics and performance were in the cultivar 504 Dezful. Examining the results related to the interaction effect of irrigation × variety showed that the variety 504 Dezful under the conditions of 90% of the field capacity has the highest amount of grain yield (3748 kg/ha), oil yield (916.41 kg/ha) and protein yield (1351.53 kg/ha). Also, this cultivar was superior to cultivars in all levels of low irrigation. In general and according to the obtained results, Dezful cultivar 504 was identified as the most resistant cultivar and Sari cultivar as the most sensitive cultivar to drought stress.
