Jasmonic acid (JA) and salicylic acid (SA) are important phytohormones involved in plant resistance against insect herbivory and pathogen infection. Application of JA and SA induces several defensive traits in plants. Here we investigated the effect of JA and SA on trichome density in five groundnut genotypes [ICGV 86699, ICGV 86031, ICG 2271, ICG 1697 (resistant) and JL 24 (susceptible)]. The ...

There is a need to incorporate nutrition into aspects of crop and water productivity to tackle food and nutrition insecurity (FNS). The study determined the nutritional water productivity (NWP) of selected major (groundnut, dry bean) and indigenous (bambara groundnut and cowpea) grain legumes in response to water regimes and environments. Field trials were conducted during 2015/16 and 2016/17 a...

The effect of cooking duration on the chemical, physical and thermal properties of bambara groundnut were investigated. The samples were analyzed for chemical composition, physical properties (length, width, and thickness, arithmetic mean, geometric mean, sphericity, surface area and aspect ratio) and thermal properties (specific heat capacity, thermal conductivity and thermal diffusivity). Dat...

The effects of a superphosphate (SP) and a rock phosphate (RP), with equal total P contents, on the growth and mineral nutrition responses of mycorrhizal and nonmycorrhizal cowpea, pigeon pea and groundnut were investigated in a pot experiment using an air-dry gamma ray-sterilized (1.5Mrad) Andisol subsoil. Adequate amounts of micronutrients were added to the pot soils as supplements. The plant...

Background and Aims Intercropping systems contain two or more species simultaneously in close proximity. Due to contrasting features of the component crops, quantification of the light environment and photosynthetic productivity is extremely difficult. However it is an essential component of productivity. Here, a low-tech but high-resolution method is presented that can be applied to single- an...

Cassava is a staple mostly eaten in the form of gari, after rice in Liberia. The local method of gari processing often leads to product contamination, thus, a study was done to assess the heavy metals and microbial contamination of gari in eight counties of the country. A total of sixty-one gari samples were collected and packaged in an airtight polyethylene bag for analyses, using standard met...

The occurrence of moulds and aflatoxins in groundnut kernels are of great concern to food processors and consumers because of their ability to cause spoilage resulting to economic losses and public health problem such as aflatoxicosis. This study was aimed at determining the presence of Aspergillus species and aflatoxin levels in fresh harvested and stored groundnuts kernels from non-mechanized...

Amplified fragment length polymorphism (AFLP) was used to assess genetic diversity among 100 selected bambara groundnut [Vigna subterranea (L.) Verdc] landraces from a diverse geographic area of Tanzania. Eleven informative AFLP primer combinations generated a total of 49 scorable polymorphic amplification fragments across the bambara groundnut accessions. Genetic distances between all accessio...

The groundnut (Arachis hypogaea L.) is one of the important food legume crops of tropical and subtropical parts of the world. It is the world’s most popular oilseed crop cultivated in more than 100 countries in all the six continents. Groundnut kernel contains above 40% edible oil, around 25% protein and 18% carbohydrates along with minerals and vitamins. Groundnut oil is free from cholesterol ...

Primary carcinoma of the liver or hepatoma, is a disease with a striking geographic distribution. It appears to be most uncommon in the United States' and Scandinavia,2 while its incidence reported to date is greatest in Africa south of the Sahara.23 Of particular interest is the fact that Negroes in the United States have an incidence of hepatoma almost identical to the white population, and t...
