Soybean (Glycine max L.) root disease, canopy microclimate, growth, and yield in a tree-based intercrop and in an adjacent monoculture
Bibliographic record
Abstract
Tree-based intercropping is an agricultural system where trees are established in rows, creating alleys that allow the mechanized production of crops. In 2004--05, soybean root disease and yield were studied at the Agroforestry Research Site (established 1987--88, in Ontario, Canada) an intercrop with ten tree species. Soybean patches with symptoms of root rot and interveinal chlorosis were observed close to black walnut trees only. Symptoms resembled sudden death syndrome and were caused by 'Fuserium solani'. In a hydroponic study, plants challenged with juglone, a black walnut allelopathic compound, and 'F. solani' were more diseased than plants challenged with 'F. solani' only. Soybean intercropped with poplar showed no disease patches, but the crop canopy water vapour pressure was 0.23 kPa lower than in monoculture because of tree competition. Moreover, yield of healthy soybean in intercrop with black walnut or pecan was not different from monoculture but with poplar or silver maple yield was 65% lower than in monoculture.

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.
