Efeito das práticas de manejo no rendimento e na perda de sementes em trigo duro sob condições áridas
Palavras-chave:
trigo duro, perdas de rendimento, emergência, colheita mecânica
Resumo
Apesar da expansão da irrigação, os rendimentos de trigo duro na Argélia permanecem substancialmente abaixo do potencial genético. Este estudo quantificou as perdas na emergência, naturais e mecânicas sob condições áridas irrigadas na província de Laghouat, Argélia durante 2024-2025. Cinco campos experimentais (variedade Vitron) foram monitorados, medindo densidades de emergência, componentes do rendimento potencial, rendimento pré-colheita e rendimento colhido. As perdas na emergência (24-43 %) foram compensadas através do afilhamento (r = -0,996; p≤0,001), embora densidades excessivas (> 600 sementes.m-2) aumentassem as perdas sem benefício no rendimento. O rendimento potencial variou entre 9,3 e 13,7 t.ha-1, sendo o número de grãos por espiga o determinante principal (r = 0,994; p≤0,001). As perdas naturais (12-38 %) foram amplificadas por condições meteorológicas extremas (granizo, chuva de 36 mm.h-1, 14 de maio de 2025). As perdas mecânicas (31-47 %) excederam os padrões internacionais (3-7 %). As perdas acumuladas atingiram 54-60 % do potencial, valorizando entre 40 e 46 %. A otimização deve priorizar a redução de perdas mecânicas, rotações com leguminosas e semeadura em linha com densidade moderada.
