Abstract
Senegalia macrostachya, ex-Acacia macrostachya is a multiple-use species providing many benefits to populations in arid and semi-arid regions. Despite its importance, limited research has been undertaken on its silviculture, growth, and productivity in plantations or in the wild. In this paper, we widely deployed the Generalized Additive Models for Location, Scale and Shape to identify factors controlling the temporal variability in S macrostachya annual pod and seed production. Data (survival rate, basal diameter, total height of each individual tree, and weight of pods and seeds produced) were collected from a factorial experiment testing different nursery production periods and the field performance of S. macrostachya under well-watered and water-stressed conditions. Long-term climate data were analyzed and the Standardized Precipitation–Evapotranspiration Index (SPEI) was calculated. Results showed that seedling survival and both height and radial growth were significantly influenced by seedling age at outplanting, watering, and climate aridity. The watered seedlings had the highest survival rate and grew taller than the non-watered seedlings. The watered seedlings also had the largest basal diameters, along with the highest pod and seed weights. There was temporal variation in S. macrostachya pod and seed production over time, indicating a cyclic production, depending mainly on climate factors. Seedling age at outplanting, early watering of outplanted seedlings, and climate aridity significantly influence not only seedling survival and growth parameters but also determine the levels of pod and seed production of S. macrostachya. Our results provide field-based evidence of the performance of this important species in the production of pods and seeds. The results also highlight the potential for domestication of S. macrostachya including use in plantations to help restore degraded rural landscapes in arid and semi-arid regions.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
