Susceptibility of common bean cultivars to storage fungal pathogens

In Menoua Division, common bean (Phaseolus vulgaris L.) is amongst the legumes which are greatly cultivated with farmers growing different cultivar types. Upon harvest, these cultivars are stored to be used as food over the storage period or for sale. Unfortunately, appropriate facilities for storing the cultivars after harvest are not available hence predisposing the grains to fungi infection. The knowledge of cultivars resistant to damage by storage fungi would therefore&nbsp...

Mycotoxin contamination of stored maize in Kenya

In Kenya, maize is a staple food and is stored after harvest as a source of food and for sale. From the stored maize, the surplus from that meant for food is sold by some farmers to earn income. The quality of the maize in store depends on the storage facility. Poorly constructed and unmaintained structures may allow leakage of water and entry by rodents and insects which may mechanically damage the maize by nibbling and holing respectively, thus predisposing the grains to...

Evaluation Of Root- Knot Nematode Management Strategies Based On Nematode Distribution In Tomato (Solanum Lycopersicum) Fields In Mwea, Kirinyaga County, Kenya

Plant parasitic nematodes (PPN), particularly root-knot nematodes (RKN) are a serious pest problem in smallholder tomato farms in Kenya. For sustainable food production, effective management of plant parasitic nematodes is essential. Rootknot nematode management is primarily dependent on the application of chemical nematicides and the use of resistant varieties. However nematicide application is often done uniformly regardless of the relative nematode distribution in the farms, and yet ...

Host Resistance And Interaction Between Root Knot Nematodes And Fusarium Wilt Of Tomato

ABSTRACT Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops grown worldwide, owing to its nutritive value, income generation and diversified use. Tomato cultivation in the coastal region of Kenya is limited by root knot nematodes (Meloidogyne spp.) and Fusarium oxysporum. A survey was done in five farming counties of the Coastal region of Kenya. Meloidogyne spp. and F. oxysporum were isolated from diseased tomato plants and identified. Host resistance and intera...

Agronomic Evaluation And Molecular Genotyping Of Selected Soybean (Glycine Max (L) Merril) Varieties Grown In Different Environmental Regions Of East Africa

ABSTRACTSoybean (Glycine max. (L)Merril) is one of the most popular pulses in the world. It has been known to man for a long time since its first record goes as far as 2500 BC in China and Manchuria. Glycine max belongs to the subgenus soja, which also contains G. soja and G. gracilis. Soybean is grown primarily for the production of seed, has a multitude of uses in the food and industrial sectors, and represents one of the major sources of edible vegetable oil and of proteins for livestock f...

Effects of Rhizobium Inoculation Rate on Yield and Yield Components of Faba Bean (Vicia faba L.)

Faba bean (Vicia faba L.) is economically an important crop in Ethiopia. The productivity of Faba bean in Ethiopiahas been declined due to poor management practices of Bio fertilizer rates usage. Three rates of Bio fertilizer (0,500 and 750gha-1) treatments were laid out in RCBD with three replications. Days to 50% flowering, days to 90% physiological maturity,plant height, number of productive tillers, total biomass yield, numbers of pods per plant, number of nodule per plant, effectivenodul...

Review on: Response of bread wheat (Triticum aestivum L.) to seeding rate on yield and yield components

Bread wheat (Triticum aestivum L.) is an economically important crop. However, its annualproductivity is very low due to poor management practices like: inappropriate seeding rate andutilization of different fertilizer types. Therefore, paper to review the response of bread wheat (Triticumaestivum L.) to seeding rate on yield. Based on this review, application of different seeding rates hassignificant effects on yield and yield components of bread wheat. The results of this review showedthat ...

Review paper on Soybean weed

The existing paper is review quite a number lookup findings on weeds and weed control in soybean.Soybean is the most important oil seeds and grain legume crop in the world, in terms of wholemanufacturing and international trades. However, losses due to weeds have been one ofthe fundamental limiting factors in soybean production. So, successful weed manipulate is one of themost essential practices for low-priced soybean production. Weeds that germinated at the identical time assoybeans grow fa...

Review on effect of Nitrogen and Phosphorous application on seed yield and nutrient uptake of onion (Allium cepa L.)

Onion is a herbaceous biennial monocot cultivated as an annual crop. The number of flowers opening oneach day was influenced by hours of sunlight and concentration of phosphorous (P) and nitrogen (N). Nand P treatments tended to lower bolting percentages. The yield of onion seed per plant increased as thenitrogen in the nutrient solution increased where seed stalks were produced. The effect of early dressingsof N on crops grown under conditions when nights are becoming cooler is shown to allo...

Review on: Effect of seed storage period and storage environment on seed quality

Seed quality deterioration is inevitable process. Since seed is a vital input in agriculture which determines not justthe production but also the productivity, it is crucial to maintain the seed quality as well as seed vigor during the storage. Storageis a basic practice in the control of the physiological quality of the seed and is a method through which the viability of the seedscan be preserved and their vigor kept at a reasonable level during the time between planting and harvesting. Many...

The Effect Of Sodium Selenite By Studying Their Biochemical Components And Plant Height

ABSTRACTDrought is a period of dryness especially when prolonged or when there is occurrence ofpersistent abnormal moisture deficiency, although drought is natural but it can be inducedartificially under a controlled envirornnent. This study aimed at studying the effect of sodiumselenite by studying their biochemical components and plant height. The seeds were collected atIIT A (INTERNATIONAL INSTITUTE OF TROPICAL AG RI CULTURE), Ibadan, Nigeria.Soil was collected and dried for 4 da...

Establishing A Method For The Mass Propagation Of Piper Guineense (Schumach) Via Tissue Culture.

ABSTRACTPiper guineense (Schumach) has great potentials for economic exploration because of theproven use of its medicinal content in human health. The plant material is usually obtained fromthick forests by women who have to walk long distances in the bush to reach it. A technique thatimproves its propagation and domestication, such as tissue culture, becomes necessary. Thisstudy was therefore initiated to develop a method for the mass propagation of Piper guineenseseedlings using...

Screening Of Cassava Plant In Oye Ekiti For African Cassava (Manihot Esculenta)Crantz, Mosaic Disease (Cmd) Infection By Polymerase Chain Reaction(Pcr)

ABSTRACTSCassava is vulnerable to a broad range of diseases caused by viruses. Among them, cassavamosaic disease (CMD) is the most severe and widespread, limiting production of the crop in subSaharanAfrica.CMD-affected cassava plants produce few or no tubers depending on the severityof the disease and the age of the plant at the time of infection. CMD is one of the majorconstraints for cassava production in Nigeria. This study was therefore undertaken to determinethe extent of CMD i...
