Intercropping Sorghum and Soybean Efficiency Using Contour Ridges Technology in Southern Mali
Bibliographic record
Abstract
Kani and Noumpinesso are two neighboring villages in which soil degradation is mainly caused by runoff and erosion. Contour ridges tillage (CRT) was identified as a runoff and erosion controlling technology while improving soil moisture and nutrient availability for crops. CRT technology associated with sorghum and soybean based intercropping system was assessed during 2017 and 2018 cropping season in an experiment under split plot design. Intercropping systems highly increased sorghum and soybean growth and yields. Sorghum grain yield, biomass yield, height and diameter were increased by 62, 51, 22 and 19%, respectively by intercropping. Soybean grain yield, biomass yield, height and diameter increased by 47, 30, 25 and 25%, respectively. Intercropping sorghum with soybean had an advantage with a Land Equivalent Ratio (LER) of 1.54 and 1.44 in 2017 and 2018 respectively. The technology of CRT added 40, 39, 25 and 21% on sorghum grain yield, straw yield, height and diameter respectively. The same parameters with soybean were greater by 52, 48, 38 and 35%, respectively. The application of CRT was economically profitable with a Value to Cost Ratio (VCR) of 3.3 and 3.0 in sorghum production and 12.8 and 9.2 in soybean production during 2017 and 2018 respectively.

How this classification was reachedexpand
Full frame distilled prediction
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
