Abstract

Field trials had carried out at the Agricultural Experiment Station of the Desert Research Center at El-Kharga Oasis, New Valley Governorate, Egypt, during 2021 and 2022 summer seasons. The effect of intercropping sorghum on peanut and using subsurface irrigation system under heat stress conditions on peanut productivity in New Valley Governorate was evaluated. Results indicated that all studied peanut parameters were increased due to application of subsurface irrigation and intercropping systems. The highest values of peanut production were obtained when applying subsurface irrigation at a depth of 30 cm. Whereas, the percentages increased when percolation lines was buried at a depth of 30 cm, surface irrigation of seed yield were 56.8 and 54.65% and water use efficiency (WUE) were 77.36 and 74.93% in the first and second seasons, respectively. The maximum values of peanut parameters regarding intercropping systems were obtained by intercropping peanut with sorghum at the rate of 2 peanut plants: 1 sorghum plant, the percentages of increase in seed yield were 40.6 and 39.54% and WUE were 40.42 and 37.35% as compared to planting peanut alone without intercropping (control) in both seasons, respectively.
