Resumo

To mitigate the negative effects of climate, the use of resilient agriculture is essential. This study evaluated the impact of different levels of biotic mulch on irrigated forage cactus yield, phenology and economic indices. The 'Orelha de Elefante Mexicana' clone was used and subjected to four levels of biotic mulch-BM (0, 5, 10 and 15 Mg ha-1) in a randomised block design with four repetitions. The treatments consisted of growing forage cactus with 0, 5, 10 and 15 Mg ha-1 mulch. The experiment was carried out in a semi-arid environment in Brazil (Serra Talhada, Pernambuco State) over two successive cycles (August 2020 to August 2022). The yield, cutting time, and morphophysiological, economic and water use indicators were evaluated. There was no effect of the BM level on the final forage yield. In the first experimental cycle, the treatment with 10 Mg ha-1 BM brought the cutting time forward by 103 degrees C day. The application of 15 Mg ha-1 BM prolonged phenophase 2, causing an increase of 236 degrees C day in the cycle compared with the treatment with 10 Mg ha-1 BM. We concluded that mulch improved crop water and economic indicators, contributing to sustainable forage production in semiarid environments. R & eacute;sum & eacute;Pour att & eacute;nuer les effets n & eacute;gatifs exerc & eacute;s par le climat, l'utilisation d'une agriculture r & eacute;sistante au climat est essentielle. Cette & eacute;tude a & eacute;valu & eacute; l'impact de diff & eacute;rents niveaux de paillis biotique sur le rendement, la ph & eacute;nologie et les indices & eacute;conomiques du cactus fourrager irrigu & eacute;. Le clone 'Orelha de Elefante Mexicana' a & eacute;t & eacute; utilis & eacute; et soumis & agrave; quatre niveaux de paillis biotique-PB (0, 5, 10 et 15 Mg ha-1) dans un plan en blocs al & eacute;atoires avec quatre r & eacute;p & eacute;titions. Les traitements comprennent la cultivation du cactus fourrager avec le paillis de 0, 5, 10 et 15 Mg ha-1. L'exp & eacute;rience a & eacute;t & eacute; men & eacute;e dans un environnement semi-aride au Br & eacute;sil (Serra Talhada, & Eacute;tat du Pernambouc) sur deux cycles successifs (d'ao & ucirc;t 2020 & agrave; ao & ucirc;t 2022) dans le champ agricole de l'UFRPE/UAST. Le rendement, le temps de coupe, les indicateurs morpho-physiologiques, ainsi que les indicateurs & eacute;conomiques et d'utilisation de l'eau ont & eacute;t & eacute; & eacute;valu & eacute;s sur deux cycles. Il n'y a pas eu d'effet des niveaux de PB sur le rendement final du fourrage. Lors du premier cycle exp & eacute;rimental, le traitement avec 10 Mg ha-1 de PB a avanc & eacute; le temps de coupe de 103 degrees C jour. L'application de 15 Mg ha-1 de PB a prolong & eacute; la phase ph & eacute;nologique 2, entra & icirc;nant une augmentation de 236 degrees C jour du cycle par rapport au traitement avec 10 Mg ha-1 de PB. Nous avons conclu que l'utilisation de paillis a am & eacute;lior & eacute; les indicateurs & eacute;conomiques et hydriques de la culture, contribuant ainsi & agrave; une production fourrag & egrave;re durable dans les environnements semi-arides.
