Detection and quantification of cow milk adulteration using portable near-infrared spectroscopy combined with chemometrics

Milk adulteration is a common phenomenon in many countries, which draws extensive attention from humans due to health hazards that might result in some fatal diseases. In this study, a portable near-infrared (NIR) spectrometer combined with multivariate analysis was used to detect and quantify milk adulteration. Fresh cow milk samples were collected from eight dairy farms in Beijing and Hebei province of China. Water,...

Evaluation of different methods of multiplying sweet potato planting material in coastal lowland Kenya

Sweet potato (Ipomoea batatas (L.) Lam.) is a staple food that contributes to food security for communities in sub-Saharan Africa. The production of sweet potato in coastal Kenya is low and this has been associated with shortage of planting material during the rainy season. A study was therefore conducted at the Pwani University farm to assess the production of sweet potato planting material using cuttings planted under...

Yield response and economic benefits of groundnut to phosphorus fertilization and inoculant rates in Northern Ghana

Groundnut (Arachis hypogea L.) is a major source of dietary protein, cultivated for both human and animal consumption. However, in West Africa, the yields are low, renewing the interest to evaluate groundnut response to P fertilizer (P) and rhizobium inoculant (IR) application. A study was conducted on the experimental field of the University for Development Studies, Nyankpala in the Northern region of Ghana to evaluate...

Effect of linear view approach of weed management in agro-ecosystem: A review

Weeds are considered a pest that is detrimental to human interest. Weeds compete with cultivated and desirable plants for space, soil nutrient, and sunlight and soil moisture thereby reducing crop productivity. Weeds also serve as a host for pests and pathogens that cause plant diseases. Weeds typically produce large numbers of seeds, assisting their spread, and rapidly invade disturbed sites. Seeds spread into natural...

Impact of water deficit on correlations and changes of some physiological traits of sweet pepper (Capsicum annuum

Changes in nutrients elements uptake, physiological characteristics, as well as, correlations analysis for these traits to each other are good factors to study the effects of drought on sweet pepper (Capsicum annuum L. cv., commercial hybrid) and disclose physiological reaction to several specific levels of stress from water deficit. Water scarcity processing was carried out by irrigating the sweet pepper plants with...

Managing various Musa varieties cultivated in Pissa district in the Central African Republic

The diversity of cultivated crops, kernel element of food security, seems today to be threatened by contemporary worldwide, regional and local agricultural mutations. This study shows that there are thirty seven (37) accessions among which one can find Musa paradisiaca (33), Musa sapientum (03) and Musa nana (01). This sharing does not depends on the ethnic diversity because many ethnic groups share among themselves a...

Effect of sodium hydroxide treatment in ginger lily forage (Hedychium gardnerianum, Sheppard ex Ker-Gawl) as forage for animal feeding

This study evaluated the effect of sodium hydroxide (NaOH) on the chemical composition (fibrous structure) and nutritive value of Hedychium gardnerianum (ginger lily), a fibre source traditionally used in ruminant feeding in the Azores. Ginger lily samples were manually harvested and dried in a forced-air oven at 65ºC until constant weight. Treatments were applied by spraying the ginger lily with a NaOH solution at...

Characterization of sugarcane germplasm collection and its potential utilization for evaluation of quantitative traits

This study was designed to determine the accession series with the most outstanding characteristics and the interrelationships among the variables. It also evaluated variability among the principal components and determined sugarcane accessions studied with similar characteristics from forty sugarcane accessions. Twelve quantitative traits were selected for data analysis. Series C accessions exhibited the most desirable...

Effects of land fragmentation on farm efficiency in three agro-ecological zones of Embu County in Kenya

This paper is based on a study that was carried out to evaluate the effect of land fragmentation on farm efficiency in three agro-ecological zones of Embu County in Kenya from July 2017 to March 2018. The study used data collected from 384 farm-households that were randomly selected from three agro-ecological zones (AEZs) in the Embu County, using the multistage stratified sampling method. The AEZs were the...

Response of seven African eggplant (Solanum macrocarpon L.) cultivars produced in Benin to salinity stress at seedling stage

Salt stress is one of the abiotic factors that cause a depressive effect on plants. This work aims to evaluate the effect of salt stress on growth of young plants of 7 cultivars (Adja-ouere, Côte d’Ivoire, Dangbo, Kpinman, Kombara F1, Lanman and Togan) of African eggplant (Solanum macrocarpon) produced in Benin, locally called Gboma, in order to determine their relative salt-resistance levels. Five NaCl...

Traditional solar salt production in Lower Casamance (Senegal): Environmental and socio-economic benefits and disadvantages

To produce salt, women in Lower Casamance (southern Senegal) traditionally practice artisanal fire salt-farming (AFS) by heating a brine with a biofuel (mangrove wood). The thermal energy produced favors the evaporation of water, the saline concentration and the precipitation of crystallized salts. In recent years, artisanal solar salt-farming (ASS) has been introduced in the region using the thermal energy provided by...

Perception and adoption of new agricultural technologies in a Northern Inland Mozambique

The debate on the factors constraining the adoption of agricultural technologies in Southern African countries is still open. This paper assesses the perception and the level of adoption of a set of agricultural technologies by the key actors in a Northern Inland Mozambique. These key actors formed two groups: (1) Technicians, who are the local government officials and are responsible for the adoption of agricultural...

Effect of phosphorus fortified compost on growth and yield of maize (Zea mays L.) and Lablab (Lablab purpureus L.) intercropped maize in acidic soils of Western Kenya

Phosphorus deficiency majorly constrains maize (Zea mays L.) production in acidic soils of western Kenya. This requires high doses of expensive inorganic P fertilizers to correct. Recommended rock phosphates and manures are lowly adopted because of low solubility and P content respectively. A Randomized Complete Block Design experiment was conducted for two seasons to assess effect of a cheaper alternative P source,...

Contribution of soil macro-fauna diversity and abundance to soil fertility enhancement in cocoa-based (Theobroma cacao) agroforestry systems in the Littoral Region of Cameroon: An appraisal of cocoa farmers’ local knowledge

Soil macro-fauna diversity and abundance greatly influence soil fertility. However, little has been done to confirm this hypothesis in cocoa-based agroforestry systems. It was in this light that this research work was undertaken in order to fill the knowledge gap. Through the use of a mixed research method for data collection and appropriate data analysis procedures, findings showed that diverse soil macro-fauna were...

Variation in genetic variability and heritability of agronomic traits in Faba bean (Vicia faba L.) genotypes under soil acidity stress evaluated with and without lime in Ethiopia

Fifty faba bean is a multipurpose crop used as human food, animal feed, soil fertility restoration and income source for farmers and the country at large. However, the productivity of this crop is low as constrained by biotic and abiotic factors in which soil acidity takes the lions share in the highlands of Ethiopia. In order to estimate genetic variability on grain yield and related traits under soil acidity stress,...
