Seleção de coquetéis de plantas de cobertura para o Município de Cruz das Almas

Abstract

Soil conservation is an agricultural practice that prioritizes the preservation of soil integrity and seeks to minimize human interference in natural processes. The use of cover crops, also known as green manures in this system, can contribute to its conservation. The present work aimed to evaluate the dry matter (DM) production of different vegetable cocktails and the best cutting time. The experiment was conducted from May 12th to August 2nd, 2023 on the experimental farm of the Federal University of Recôncavo da Bahia, located in the municipality of Cruz das Almas, Bahia. The experimental design was in randomized blocks (DBC), in a strip scheme, where the treatments consisted of the evaluation of 7 plant cocktails (mix) with 3 cutting dates (60, 70 and 80 DAP). The species used to compose the topping cocktails were: White oat (Avena sativa L.), black oat (Avena strigosa Schreb), ryegrass (Lolium perenne), barley (Hordeum vulgare), Crotalaria juncea (Crotalaria juncea L.), vetch common (Vicia sativa L.), forage turnip (Raphanus sativus L.), millet (Pennisetum glaucum), lupine (lupinus albus) and sunflower (Helianthus annus) and buckwheat (Fagopyrum esculentum). There was a significant difference in DM production only for the mix 3 treatment. Mix 1 and Mix 5 cocktails are recommended for cutting at 70 DAP. The other cocktails showed a higher production at 80 DAP.
