Growth and Production of Cultivars Ornamental Sunflower Irrigated With Water of Different Salinities
Bibliographic record
Abstract
The sunflower (Helianthus annuus L.) appears as an income alternative to the producers of the northeastern region of Brazil, however limited by the salinity present in the waters of the region, which makes it necessary to select cultivars that are more adaptable to this situation. On this, the objective was assessing the development of two cultivars of cutting ornamental sunflower with waters of different salinities. The experiment was performed in conditions of protected environment at UFCG, CCTA-Pombal-PB. It was performed in outline of blocks in factorial scheme 5 × 2, being five saline levels (N1 = 0.3, supply water; N2 = 1.5; N3 = 2.7; N4 = 3.9; and N5 = 5.1 dS m-1) and two cutting ornamental sunflower cultivars (Red Sun and Vincents II), with four repetitions and two plants by portion, with a total of 80 experimental units. The irrigation water salinity affected all the analyzed variables, up to estimate level of 2.7 dS m-1 acceptable reductions happen of 10% in the inflorescence and stem of cultivars of ornamental sunflower. The Red Sun cultivar when compared with cultivar Vincents II demonstrated better results in the studied variables.

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.
