Abstract

fetched live from OpenAlex

Este trabalho teve como objetivo avaliar o crescimento de mudas de maracujazeiro- amarelo em três diferentes tamanhos de recipientes, em três condições de cultivo protegido, utilizando seis diferentes substratos. Foram empregados três ambientes de cultivo: (A1) estufa em arco, coberta de filme de polietileno de 150 μm, abertura zenital e tela termorrefletora de 50% sob o filme; (A2) viveiro agrícola de tela de monofilamento, com 50% de sombra; e (A3) viveiro agrícola de tela termorrefletora, com 50% de sombra. Foram testados três volumes (V1 = xx cm³ -sacolas de polietileno de 7,5 x 11,5 cm; V2 = xx cm33 - sacolas de polietileno 10,0 x 16,5 cm; e V3 = xx cm33 -sacolas de polietileno de 15,0 x 21,5 cm) e seis substratos (S1 = solo; S2 = Plantmax®; S3 = vermiculita; S4 = fibra de coco; S5 = fibra de coco chips; e S6 = Organosuper®, composto orgânico comercial). O delineamento experimental foi inteiramente casualizado, em esquema de parcelas subsubdivididas, em que os ambientes foram as parcelas, os recipientes de diferentes volumes as subparcelas e os substratos as subsubparcelas. Aos 50 dias após a semeadura, foram medidos a altura das plantas, o comprimento da raiz, a massa de matéria seca da parte aérea e das raízes. A partir das massas de matéria seca determinaram-se a relação massa de matéria seca de parte aérea e raiz e massa de matéria seca total. A estufa foi o melhor ambiente quando se utilizou o recipiente de XX cm33 o qual proporcionou mudas maiores, com maior biomassa seca aérea, radicular e total. A vermiculita foi o melhor substrato, porém o solo adubado é uma alternativa menos dispendiosa para a região.

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.
