Good management of soil and water use is one of the most important factors in agricultural sustainability, and intercropping systems are an important component of good agricultural practices. Thus, a field experiment was conducted at the Experimental Farm of Arab Al-Awamer Research Station, Assiut Governorate, Agriculture Research Center, Egypt, during the summer seasons of 2021 and 2022 to investigate the effect of maize (M) + peanut (P) intercropping system on productivity, water use efficiency, and profitability at varying irrigation regimes. The experiment was laid out in a randomized complete block design using a split-plot arrangement with three replicates. Irrigation regimes (120, 100 and 80% ETc) were assigned to the main plots, while the intercropping systems (100% P + 25% M, 100% P + 33% M and 100% P + 50% M) were allocated to the sub-plots. The results showed that most traits of peanut and maize decreased substantially under the 80% ETc irrigation regime. While the largest values of traits were associated with the 120 % ETc. Averaged across the two seasons, the highest values of net return (1,441 US$/ha) were obtained when 100% peanut plants were intercropped with 25% maize at 120% ETc irrigation regime. Therefore, we recommend intercrop maize (25%) with peanut (100%) irrigated with 120% ETc to achieve higher yields and net return. DOI: http://dx.doi.org/10.5281/zenodo.10413383
