... Recovery of arsenic contaminated areas is a challenge society faces throughout the world. Revegetation associated with microbial activity can play an essential role in this process. This work investigated biological attributes in a gold mining area with different arsenic contents at different sites under two types of extant revegetation associated with cover layers of the soil: BS, Brachiaria sp. ...
... In terrestrial ecosystems, plant growth, plant community structure, and ultimately the ecosystem services provided by plants are dependent on the presence and composition of below ground arbuscular mycorrhizal (AM) fungal communities. AM fungi form obligate symbioses with plants providing nutrients to their host plants in exchange for photosynthates. While AM have been found in most wetland ecosys ...
... Nine oleanane saponins including three new and six known were isolated from the seeds of Sesbania vesicaria. The new saponins were established as 3-O-[α-l-rhamnopyranosyl-(1→3)]-β-d-glucuronopyranosyl-3β,29-dihydroxy-olean-12-en-28-oic acid, 3-O-α-l-rhamnopyranosyl-28-O-β-d-glucopyransoyl-3β-hydroxy-olean-12-en-23-al-28-oate, and 3-O-α-l-rhamnopyranosyl-28-O-β-d-glucopyransoyl-3β,23-dihydroxy-olea ...
... During the production of seedlings, the substrate has a significant influence on plant growth, which can be used in an original or combined form. This has made necessary studies to obtain substrates able to ensure adequate growth of the seedlings grown in nurseries. With to contribute to the knowledge of the specie Sesbania virgata (Cav.) Pers, this study determined the best ratio of the component ...

Abstract:
... In the rice–wheat (RW) systems of the Indo-Gangetic Plains of South Asia, conservation tillage practices, including zero-tillage (ZT), are being promoted to address emerging problems such as (1) shortages of labor and water, (2) declining factor productivity, (3) deterioration of soil health, and (4) climate change. Despite multiple benefits of ZT, weed control remains a major challenge to adoptio ...

... Maize production in Malawi is limited mainly by low soil N and P. Improved fallows of N-fixing legumes such as Tephrosia and Sesbania offer options for improving soil fertility particularly N supply. The interactions of Tephrosia fallows and inorganic fertilizers on soil properties, N uptake, and maize yields were evaluated at Chitedze Research Station in Malawi. The results indicated that the lev ...
