Immunoassay methods are available for detection and quantitation of proteins expressed by most biotechnology-derived crops in commercial production. The 2 most common test formats are enzyme-linked immunosorbent assay (ELISA) and immunochromatographic (lateral flow) strip tests. Two ELISA methods, one for Roundup Ready soybeans and one for MON810 CrylAb corn, were the subject of large internati...

The objective of this study is to investigate tungsten (W) contamination in soil and its enrichment in rice in the area of the world's largest and longest-operating W mines in China. Root zone soil and rice plants were sampled at 15 sites in the agricultural field adjacent to W mines and analyzed for Al, Fe, Mn, Sc, and W contents and W chemical forms in the soil samples and W contents in the r...

Grain beverages are processed from legumes and cereals such as soya beans, maize, rice, sorghum, millet among others [1,2]. They are rich sources of vitamins, minerals, carbohydrates, fats, oils, and protein. Grains beverages include soya milk, grain milk, ogi and kunu products among others. These beverages are among the most widely consumed food products in many developing countries and play v...

Dielectric properties of materials are defined, and the major factors that influence these properties of agricultural and food materials, namely, frequency of the applied radiofrequency or microwave electric fields, and water content, temperature, and density of the materials, are discussed on the basis of fundamental concepts. The dependence of measured dielectric properties on these factors i...

Agricultural policy reform has been an important source of change in the Chinese agricultural sector. The reforms led to productivity growth and helped China in pursuing its self-sufficiency goal especially in the grain sector. To analyse whether observable productivity growth stems from technologically induced components, or from the market induced parts, a multi-input-multi-output model is de...

Processing of meat and crops accounts for a large share of manufacturing in Sub-Saharan Africa (SSA). The paper assesses empirically the impact of hypothesized productivity change in agro-food processing on growth, trade, employment, and input and output prices in SSA, using a 13 commodity, 7 region version of the Global Trade Analysis Project (GTAP) applied general equilibrium model with a 199...

This paper employs multiple regression analysis to evaluate the effectiveness of yieldraising techniques available to medieval farm managers (reeves) using a panel dataset of 49 manors held by the Bishop of Winchester from 1349-70. There are three main interesting findings. First, annual weather variation, modelled with climate reconstructions, was highly significant in explaining annual yield ...
