Ao final do experimento foi determinada a quantidade de micronutrientes absorvida pela planta, bem como a necessidade micro nutricional da planta em cada etapa de crescimento. O experimento foi desenvolvido em área do Departamento de Recursos Naturais - Ciência do Solo da Faculdade de Ciências Agronômicas, campus de Botucatu. Os tratamentos constaram de oito épocas de coleta de planta (0, 20, 40, 60, 80, 100, 120, e 140 dias após o transplante das mudas) e quatro repetições, sendo cada repetição formada por quatro plantas. A fertirrigação foi via gotejamento. Os resultados de extração de micronutrientes demonstraram que o maior desenvolvimento da planta, conseqüentemente, sua maior necessidade nutricional de B, Cu, Fe, Mn e Zn, se concentra no período entre 120 e 140 dias após o transplante de mudas, onde verificou-se que a planta dobrou a extração total dos micronutrientes analisados em comparação ao período anterior. UNITERMOS: fertirrigação, pimentão, Capsicum annuum L., irrigação por gotejamento e acúmulo de micronutrientes MARCUSSI, F.F.N.; VILLAS BÔAS, R.L. ABSORPTION COURSE OF MICRONUTRIENTS IN BELL PEPPER PLANT UNDER FERTIGATION IN PROTECTED ENVIRONMENT 2 ABSTRACT This research aimed to determine the absorption course of micronutrients in bell pepper plants (Elisa hybrid) under fertigation using eight time periods of plant collection. At the end of the experiment the amount of absorbed and accumulated micronutrients by plants has been determined as well as the plant nutritional needs in each growth stage. The experiment was carried out at the Natural Resource Department – Soil Science at the Agricultural Science College, Botucatu campus, São Paulo state, Brazil. The treatments were eight time periods of plant collection (0, 20, 40, 60, 80, 100, 120, and 140 days after seedling transplant) and four repetitions, each one comprising four plants. The fertigation was performed through drip irrigation. The largest plant development and consequently the highest B, Cu, Fe, Mn and Zn nutritional needs occurred from 120 to 140 days after seedling transplant where the plant doubled the whole analyzed micronutrient extraction compared to the earlier period. KEYWORDS: fertigation, bell pepper, Capsicum annuum L., drip irrigation and micronutrient absorption.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
