Foram simulados 20 tratamentos, originados da combinação de cinco níveis de água no solo (60, 50, 40, 30% da Capacidade de Água Disponível 'CAD' e sem irrigação) com quatro épocas de semeadura (15/06, 15/07, 15/08 e 15/09), utilizando-se o modelo CROPGRO-cowpea/DSSAT. As simulações foram realizadas para um período de 9 anos (1990 a 1998), em Parnaíba, e 22 anos (1977 a 1998), em Teresina. A análise da estratégia ótima do manejo de irrigação foi feita com base na dominância de Gini. Os resultados evidenciaram que, nos dois municípios, a semeadura em 15/06 foi a mais favorável para o cultivo irrigado do feijão caupi, devendo-se manter o teor de água no solo em níveis de até 50% da CAD.

ECONOMIC IRRIGATION MANAGEMENT IN COWPEA CROP BY SIMULATION MODEL 2 ABSTRACT The objective of this study was to identify economic strategies of irrigation management, in the soil and meteorological conditions of Parnaíba and Teresina, Piauí, Brazil. Twenty treatments were simulated combining five soil water levels (60, 50, 40, 30 % of soil water available 'SWA' and without irrigation) and four planting dates (15/06, 15/07, 15/08 and 15/09), using the CROPGRO-cowpea/DSSAT model. The simulations included a period of 9 years (1990 to 1998) for Parnaíba and 22 years (1977 to 1998) for Teresina. The treatments were analyzed from Mean-Gini Dominance. The results showed that the best strategy is an irrigation management with 50% of SWA and a planting date in 15/06.

Full frame distilled prediction

Teacher imitation

Not 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.
