Abstract

fetched live from OpenAlex

Processing tomatoes ( Lycopersicon esculentum Mill.) are grown on ≈6000 ha in southwestern Ontario. Field experiments were conducted in 1998 and 1999 at two locations to explore the potential of alternative tillage practices (conventional, disked, zone-till, and no-till) on growth, development, yield and quality of tomatoes. Growth measurements of leaf number, plant height, stem diameter, total aboveground dry weight, and LAI did not differ with tillage system. Rye ( Secale cereale L.) used as a cover crop did not influence tomato growth or development. Yield differences ( P < 0.05) were not observed for red and green tomato fruit harvested in the conventional, disked or zone-tillage treatments. Yield reductions ( P < 0.05) were observed however, for both red and green fruit with no-tillage. The delay in crop maturity associated with no-till reduced the potential for the application of this tillage practice for tomato production. Tomato postharvest quality did not differ among tillage systems. Zone-tillage was found to be a viable alternative to the moldboard plow as a primary tillage practice for the production of processing tomatoes.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
