Cowpea [Vigna unguiculata (L.) Walp.] is an annual legume of economic importance and widely grown in the semi-arid tropics. However, high-density genetic maps of cowpea are still lacking. Here, we identified 34,868 SNPs (single nucleotide polymorphisms) that were distributed in the cowpea genome based on the RAD sequencing (restriction-site associated DNA sequencing) technique using a populatio...

Cropping systems with legumes play key roles in farming sub-Saharan Africa. However, how commonly legume associations perform low input-systems is not well-known. Here, we studied four species used three rotation upland rice, i.e., groundnut monocropping, sorghum–cowpea intercropping, and velvet bean–crotalaria two fertilization managements on the previous manure alone or complemented mineral f...

Fifteen gravid, crossbred gilts were utilized in an experiment to measure the effect of five isonitrogenous dietary treatments (12% crude protein, sorghum-soybean meal; sorghum; sorghum + lysine; sorghum + threonine; sorghum + lysine + threonine) on N balance, colostrum composition and plasma constituents (protein, urea N and IgG). All gilts were fed a standard corn-soybean meal diet from breed...

Fusarium oxysporum f.sp. tracheiphilum (Fot) is a soil-borne fungal pathogen that causes vascular wilt disease in cowpea. Fot race 3 is one of the major pathogens affecting cowpea production in California. Identification of Fot race 3 resistance determinants will expedite delivery of improved cultivars by replacing time-consuming phenotypic screening with selection based on perfect markers, the...

ABSTRACT- Declining land productivity associated with decreasing soil organic carbon and nutrients is a significant issue in monoculture production. The field experiment with different rates of fertilizer systems (60 kg ha-1 N + 100 kg ha-1 P, 300 kg ha-1 Bio-organic (organic fertilizer), 3 kg ha-1 Bioumik (biofertilizer), 30 kg ha-1  N + 50 kg ha-1 P + 150 kg ha-1 Bio-organic fertilizer and 30...

Starches were isolated from grains of waxy, heterowaxy, and normal sorghum. To study the relationship between starch structure and functionality and guide applications of these starches, amylose content, amylopectin chain-length distributions, gelatinization and retrogradation, pasting properties, dynamic rheological properties, and in vitro enzyme digestion of raw starches were analyzed. Heter...

Although sweet sorghum is in focus as a promising multi-purpose crop in semi-arid tropical regions, information on optimum nitrogen (N) management remains rather limited. To determine and understand the N dynamics in sweet sorghum-soil ecosystem, we evaluated the N recovery of applied fertilizer in the Alfisol field during the 2009 and 2010 rainy seasons. Sweet sorghum was grown under six N rat...

Nitrogen (N) availability under no-till intercropping systems has not been widely investigated in diverse agro-ecological regions Limpopo Province. Two seasons of rainfed experiments were conducted during 2018/19 and 2020/21 a 2 × 4 factorial design to measure the biological nitrogen fixation (BNF) ability cowpea an system with four grain sorghum cultivars at two test locations, Ofcolaco Syferk...

Background: Seed quality, an important determinant of germination and vigor potential, can be improved through seed priming. This study was therefore aimed at assessing the effects steeping duration inoculum concentration on seedling growth five crops priming with growth-promoting rhizobacteria. Methods: Broth cultures bacterial strains, belonging to Providencia vermicola (2 strains), P. rettge...
