Groundnut is susceptible to a range of diseases and pests owing to its narrow genetic base. Closely related wild relatives of groundnut are diploid, and crossability between diploid wild relatives and tetraploid cultivated groundnut is difficult. Amphidiploid and autotetraploid groundnuts, which are tetraploids (also called synthetic groundnut), were developed at ICRISAT. Crossability between c...

Background: Microbial and fungal contamination of agricultural produce has been a health challenge over the years. The present study surveyed microbial and aflatoxin contamination in groundnut, maize, and cowpea collected from Port Harcourt, Nigeria. Methods: Ninety samples of maize, groundnut, and cowpea were purchased from six major markets in Port Harcourt, Nigeria. The samples were first e...

This study was conducted to assess major Aspergillus species and aflatoxins associated with groundnut seeds and cake in Eastern Ethiopia and evaluate growers' management practices. A total of 160 groundnut seed samples from farmers' stores and 50 groundnut cake samples from cafe and restaurants were collected. Fungal isolation was done from groundnut seed samples. Aspergillus flavus was the dom...

Groundnut (Arachis hypogaea L.) is an annual legume which is also known as peanut, earthnut, monkeynut and ground bean. Among the major oil seed crops, groundnut has some specific advantages because of its use in many food products. The present study is planned to characterize different groundnut varieties, grown under similar conditions, for their chemical composition and nutritional assay. Fa...

The groundnut plant has the ability to survive in areas of low rainfall because it is a legume and it increases soil fertility by fixing nitrogen in the soil. The study area is known by erratic and uneven rainfall while groundnut is the main cash crop in the area. The study identified the groundnut market outlets, factor affecting groundnut market outlet choice and identifies farm level women r...

The effect of ingestion of dietary oxidized groundnut oil on the histology of wistar rat brain (cerebral cortex), liver, and kidney were examined. Female weanling rats (Rattus norvegicus) were maintained for 12 weeks on intermittently thermoxidzed groundnut oil at 15% dietary level as part of a balanced diet. Fresh (unheated) groundnut oil served as the control. Histological examination of the ...

Chlorotic ringspots or chlorotic leaf specking, terminal bud necrosis, axillary shoot proliferation and severe stunting of groundnut (Arachis hypogaea) were shown to be caused by tomato spotted wilt virus (TSWV). Cowpea (Vigna unguiculata cv. C-152) was found to be a good assay host. TSWV remained infective in buffered sap of groundnut at a dilution of 10-2’5, after storage for 4 h at room temp...

Sesame and groundnut are important crops and a source of edible oil and protein. Amino acid content of both meals was analyzed and studies made on the protein solubility of defatted sesame and groundnut meal in aqueous solution over various pH and in various salt solutions. Valine, isoleucine, arginine, aspartic acid and glutamine were present in high concentration in both the defatted meals. A...

Groundnut or peanut (Arachis hypogaea L.) is one of the important economic oilseed crops of the world. The cultivated groundnut belongs to family Fabaceae, subfamily Papilionaceae. Groundnut is grown in nearly 100 countries. It occupies 21.7 million ha worldwide with a total production of 38.6 million tonnes during 2011 (FAOSTAT, 2011). Among the soil-borne fungal diseases of groundnut, stem ro...

Seed is the basic input in agriculture. The quality of seed used by farmers determines the status of agriculture they practice. However, for maximum gain in productivity the use of both improved varieties and improved integrated crop management practices are required. Not only do they contribute to increasing productivity individually, but they also act synergistically. Seed of improved varieti...
