Morphophysiology of Eggplant Irrigated With Wastewater and Nitrogen and Phosphorus Doses in the Semi-arid Region of Brazil
Bibliographic record
Abstract
Water is a scarce resource in semi-arid regions, therefore, the correct water management is an essential practice. In this research we evaluated the use of nitrogen, phosphorus and treated wastewater on the growth and morphophysiology of eggplants (Solanum melongena L.) in the semi-arid region of Brazil. The experiment was conducted in Pombal, Paraíba, Brazil, using a randomized block design, in a 4 × 4 + 1 factorial scheme: wastewater with four nitrogen doses (N1 = 0.22; N2 = 0.39; N3 = 0.56; and N4 = 0.73 g N dm-3) and four doses of phosphorus (P1 = 0.96; P2 = 1.68; P3 = 2.40; and P4 = 3.12 g P dm-3), and the controls – distilled water fertilized with 0.56 g of N dm-3 and distilled water fertilized with 2.40 g of P dm-3. Each treatment was replicated 4 times. The nitrogen and phosphorous interaction did not influence the growth and physiological aspects of eggplant plants. Excess growing media nitrogen significantly decreased gaseous exchanges of eggplant plants, being found decreased of 4.4 μmol m-2 s-1 the CO2 assimilation.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
