Off‐season crops as a strategy for renovating degraded pastures and improving maize yield in a low‐altitude tropical region

open access: yesAgronomy Journal, Volume 117, Issue 6, November/December 2025.
Abstract Brazil can expand cultivated areas without deforestation by restoring degraded pastures and optimizing grain production through off‐season crops. This study evaluated eight off‐season treatments, including fallow, monocrops, and intercropping combinations, and their effects on maize (Zea mays L.) intercropped with guinea grass (Megathyrsus ...

Allozyme diversity of cultivated cowpea Vigna unguiculata (L.) Walp.

open access: yesTheoretical and Applied Genetics, 2000
A survey of allozyme variation in cultivar-groups of cowpea [Vigna unguiculata (L.) Walp.] was undertaken by examining 21 enzyme systems encoded by 36 loci in 271 accessions representing the five cultivar-groups. Very low levels of variation were found within accessions, which is typical of self-pollinating species.

Histamine in Brazilian Foods: A Comprehensive Review of Occurrence and Risk Assessment for Intoxication and Intolerance

open access: yesFood Science &Nutrition, Volume 13, Issue 11, November 2025.
Even though histamine plays an important role in human health, it has been associated with food intoxication and intolerance episodes. The most relevant, current state of knowledge regarding histamine's biochemical and health aspects is provided. Histamine levels are provided for 17 food groups, including 335 food types and 11,437 samples, allowing ...

Investigating the effects of low input drying procedures on maize (Zea mays L.), cowpea (Vigna unguiculata L.) and bambara groundnut (Vigna subterranea (L.) Verdc.) seed quality in Benin [PDF]

open access: yes, 2004
Four drying regimes (sun, shade, silica gel and conventional drying room) were compared using seeds of Zea mays L. (cv. DMR-ESR-W), Vigna unguiculata (L.) Walp. (cv. NI 86-650-3) and Vigna subterranea (L.) Verde. {local white va­riety).

Effects of Legume‒Cereal Rotation on Sorghum Rhizosphere Microbial Community Structure and Nitrogen‐Cycling Functions

open access: yesMicrobiologyOpen, Volume 14, Issue 5, October 2025.
Our metagenomic study revealed the impact of sorghum cultivated in soils previously grown with cowpea, soybean, and maize on rhizosphere microbiome and soil nitrogen cycling. ABSTRACT Legumes form mutualistic interactions with specific soil microbiomes that fix atmospheric nitrogen and improve soil fertility.

Identification of Candidate Genes Controlling Black Seed Coat and Pod Tip Color in Cowpea (Vigna unguiculata [L.] Walp)

open access: yesG3: Genes, Genomes, Genetics, 2018
Seed coat color is an important part of consumer preferences for cowpea (Vigna unguiculata [L.] Walp). Color has been studied in numerous crop species and has often been linked to loci controlling the anthocyanin biosynthesis pathway.

Potential of biochar‐based inoculant in enhancing rhizobia survival and grain yield of cowpea (Vigna unguiculata (L.) Walp.)

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract The need for low‐cost carrier materials is paramount for rhizobium inoculants production, especially in sub‐Saharan Africa. This research studied different feedstocks biochar as potential carriers for inoculant production. Coconut coir (CC), coconut shell (CS), rice husk (RH), and sugarcane bagasse (SB) biochars were used as carriers, and ...
