Afforestation in dry lands faces numerous challenges, particularly in regions like Darfur, Sudan, where droughts and desertification lead to forest degradation and social conflicts. This study evaluates the impact of rainwater harvesting techniques (RWHTs) on the survival and growth of Ziziphus spina-christi transplants in Nyala Agriculture Research Station Farm, South Darfur State. The experiment was conducted during March 2018 and January 2020; it tested four RWHTs: Control, Semicircular Bund, Trapezoidal Bund, and V-Shape Catchment, laid out in a 6 randomized block design with 3 replications of each technique within the block (6 blocks×4 RWHTs×3 replications=72 units, each containing one transplant). Key parameters measured included soil properties, soil moisture at various depths, transplants’ survival, and growth metrics. The soil type was clayey cambic, influenced by aridity and sand creep. Rainfall was erratic, totaling 183.2 mm, or 45.8% of the average. Mean temperature was 35.1°C; it affected transplants indirectly by lowering soil moisture storage through evaporation-transpiration. RWHTs significantly recharged soil moisture and improved transplants’ survival rates by 75%, 66.7%, 58.3%, and 25% for Trapezoidal Bund, Semicircular Bund, V-Shape Catchment, and the Control, respectively. RWHTs also increased growth metrics by following folds: 1.6 for shoot height, 1.5 for diameter, 1.9 for number of branches, 1.6 for root length, 2.3 for shoot biomass, and 1.9 for root biomass. Performance ranking of RWHTs was: Trapezoidal Bund>Semicircular Bund=V-Shape Catchment>Control. These findings suggest that RWHTs can support the establishment, survival, and growth of transplants in moisture-deficient dry lands, making them a reliable afforestation strategy for individuals and institutions.
