Feeding Preferences of The field Cricket Scapsipedus Icipe (Orthoptera: Gryllidae) For Different Species of Commelina

Abstract/Overview The field cricket, Scapsipedus icipe Hugel and Tanga (Orthoptera: Gryllidae) is edible and could be used to reduce malnutrition in Sub-Saharan Africa. As the demand for cricket products is increasing, there is a need to find cost-effective ways of rearing this cricket using locally available and affordable sources of food. This study evaluated the feeding preferences of the field cricket S. icipe for 11 species of dayflowers (Commelina spp.; Commelinaceae), using no ...

Effect of pH and magnesium on colour development and anthocyanin accumulation in tuberose florets

Abstract/Overview Anthocyanins are a group of plant pigments responsible for colors ranging from red to violet and blue. Anthocyanins are pigments that accumulate in the vacuoles of plant epidermal cells. Chroma and hue are dependent on conditions inside and outside the vacuoles. Also conditions within the vacuole that facilitate formation of complexes with several metal ions. The aim of this study was to examine changes in accumulation of anthocyanins and the resultant colour in tuberose...

Exploiting the Genetic Diversity of Vegetable African Nightshades

Abstract/Overview frican nightshades ( Solanum section Solanum ) are an important source of daily nutrients and income for small-scale farmers in sub- Saharan Africa and are a delicacy for urban inhabitants. The section is one of the most ubiquitous, largest and most diverse sp ecies groups of the genus Solanum , with more than 30 reported species. Complete profiling of the species in this section has been hampered by several morphological, cytological and taxonomic complexities. There is...

Physical qualities of organic potting substrates for containerized and nursery production

Abstract/Overview Soil has always been used as nursery and pot substrate in horticultural industry in Kenya, but it has problems related to aeration, drainage, non-uniformity and chemical suitability. Therefore, development of alternative potting substrates with optimal physical characteristics is necessary. The objective of this study was to evaluate physical suitability of forest soil (FS), compost (C), pine bark (PB), and rice husks (RH) as alternative amendments of potting substrates....

Pre- and Postharvest Factors Affecting Quality and Safety of Pepper (Piper nigrum L.)

Abstract The quality and safety of pepper (Piper nigrum L.) are a function of crop management practices, harvest maturity, harvesting methods and subsequent handling after harvest, including storage conditions and processing methods. The review shows that volatile oil decreases with shade intensity (15–30%). Essential oil, oleoresin, piperine and monoterpenes (thujene, α-pinene, sabinene, limonene, α-phellandrene and linalool) increase with altitude, while β-caryophyllene and total ...

Potentials of Spices Diet-Derived Polyphenols in Modulating the Self- Renewal of Stem Cells

Abstract Over many centuries, spices have been and are globally utilized in foods and drinks, as well as in pharmaceuticals industries. Spices are rich in health-beneficial chemical constituents that include diet- derived polyphenols, terpenes, polysaccharides, lipids, organic acids, and raw fibres. Stem cells can self- renew and differentiate into major cell types. However, malignant stem cells can invade and kill nearby tissue as well as spread to other body parts through the blood and ...

Morphological Characterization and Yield of Pepper (Piper nigrum L.) Types Grown in Morogoro District, Tanzania

Abstract Background: Pepper (Piper nigrum L.) is among key spice crops grown in Morogoro district of Tanzania. Most of the pepper types grown in the district are only known by their local names as Babu kubwa, Babu ndogo, Babu kati and Ismailia. This may limit information on germplasm collection or genetic resource for plant improvement and trade in markets with variety specifications. The aim of this study was to generate preliminary information of the pepper types based on their morpholo...

Establishment of the Causal Agent(s) of Spike Shedding and Stem Wilting of Pepper (Piper nigrum L.) in Morogoro District, Tanzania

Pepper (Piper nigrum L.) serves as a source of income to smallholder spice farmers in Morogoro district of Tanzania. Recently, spike shedding and stem wilting of pepper plants were reported to cause about 30% yield loss of the crop. 'is study was undertaken to identify the causal agent(s) of the problems. 'ree pepper gardens in each of the four hamlets (Nyange, Doga, Tandai, and Lukenge) in Tandai village (Kinole ward) were surveyed, and plant tissue and soil samples were collected for la...

Extent of Spike Shedding and Stem Wilting of Pepper (Piper nigrum L.) in Morogoro District, Tanzania

Abstract Background: Pepper (Piper nigrum L.) is an important spice produced by small-scale farmers in Morogoro district of Tanzania for both local and export markets. Recently, farmers have reported a decline in crop productivity due to spike shedding and stem wilting of pepper plants. The study was conducted to obtain baseline information on the extent of the disorders. Methods: An altitudinal transect survey was conducted in Morogoro district from October to November 2018. Data were co...

Farmers Information Literacy And Awareness Towards Agricultural Produce And Food Security: FADAMA III Programs In Osun State Nigeria

Abstract: Agriculture remains the mainstay of the Nigerian economy, because it does not only contribute to the largest share of Gross Domestic Product (GDP), it is the largest employer of labour and a key contributor to wealth creation and poverty alleviation, as large percentage of the population derive their income from agriculture and related activities . Agricultural sector is the backbone of many economies in Africa, but most African countries are yet to devote their efforts to the diss...

EFFECTS OF SOIL AMENDMENTS ON POSTHARVEST QUALITY OKRA FRUITS

ABSTRACT In Nigeria farmers apply fertilizers arbitrarily without considering the resultant effect on soil and the postharvest quality of crops. This study was therefore designed to investigate the effects of NPK fertilizer 20:10:10 on the postharvest quality of okra fruit (Abelmoschus esculentus L. Moen). Okra seeds NHE-47 were sown in the field at the National Institute of Horticultural Research (NIHORT), Idi-Ishin, Ibadan, Nigeria at a spacing of 50 cm x 25 cm. The fertilizer NPK 20-10-10 ...

EVALUATION OF POST HARVEST HANDLING OF PEPPER FRUIT (Capsicum frutescens) BY MARKETERS IN IBADAN METROPOLIS, OYO STATE, NIGERIA
