This study aimed to evaluate the leaf water potential in papaya plants at different dates, times of the day (6:00, 8:00, 10:00, 12:00, 14:00, 16:00 and 18:00) and irrigation depths to indicate the crop water deficit. The experiment followed a randomized block design, with four treatments (50, 75, 100 and 125 % of the irrigation depth required to reach the field capacity). The leaf water potential measurements between 12:00 and 14:00 showed the greatest differences among the applied irrigation depths, thus being the most suitable interval for assessing the water status. The water potential of -2.5 MPa can be used as a critical limit for ‘Sunrise Solo’ papaya plants. 2025 artículo científico 1517-6398 https://www.redalyc.org/articulo.oa?id=253081925014 https://www.redalyc.org/journal/2530/253081925014/ https://www.redalyc.org/journal/2530/253081925014/html/ https://www.redalyc.org/journal/2530/253081925014/253081925014.epub https://www.redalyc.org/journal/2530/253081925014/movil 10.1590/1983-40632025v5581185 en http://www.redalyc.org/revista.oa?id=2530 Pesquisa Agropecuária Tropical application/pdf Universidade Federal de Goiás Pesquisa Agropecuária Tropical (Brasil) Vol.55 |
