Abstract

fetched live from OpenAlex

The Water, Nutrient and Light Capture in Agroforestry Systems (WaNuLCAS) and an intelligent optimization technique, namely a Tabu Search metaheuristic were employed to select the optimum management practices for a Grevillea robusta and Zea mays (maize) alley cropping system. This agroforestry system was simulated for Embu Research Station in the Central Highlands of Kenya where G. robusta is commonly grown. The objectives for this land-use system were to maximum tree and crop production and Net Present Value (NPV). The maize production was constrained not to fall below 75% of the first crop of a sole cropped maize cropping system. The decision variables that were determined included; the tree planting density, pruning management and fertilizer application in the even-aged alley cropping system. The WaNuLCAS model simulated crop growth successful but was found inadequate for tree growth. The Tabu search heuristic was found ideal for optimizing this alley cropping system.

Full frame distilled prediction

Teacher imitation

Not 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.
