Abstract: The perception of airborne chemical signals by plants can trigger reconfigurations of their metabolism that alter their biotic interactions. While plant-to-plant chemical communication has primarily been studied in the context of eliciting defenses to herbivores and pathogens, recent work suggests that it can also affect plants’ interactions with their rhizosphere microbiomes. In this perspective, we discuss the potential for integrating the fields of plant-to-plant communication...
Abstract: Production of potatoes in the developing countries has been on the rise. This reinforces the growing importance of potatoes throughout Africa, Asia, and Latin America as a source of food and livelihood. However, this crop continues to experience major postharvest losses that are associated with a lack of effective storage facilities in these regions. This study used magnetic fields (MF) as an innovative technology to reduce potato losses while under storage. The effects of test var...
Abstract: The fall armyworm (FAW) is a major pest of maize in America and its outbreaks in 2017 in Africa threatened maize, a staple food crop in the region. The effect of parasitoids, nine synthetic insecticides, eleven botanicals, five entomopathogens and pheromone lures have been studied against FAW in 2017 and 2018. Survey conducted in Jimma, Awash Melkasa, Hawasa, East and West Gojam identified three different species of parasitoids from FAW larvae belonging to Hymenoptera and Diptera. ...
Abstract: Napier grass remains an important strategic grass species in east African mixed crop-livestock systems. However, production of several varieties of the grass remains constrained by phytoplasmic disease, Napier stunt disease (NSD), which is transmitted by the leafhopper, Maiestas banda. For smallholder farmers of western Kenya who rely on the grass for livestock feed and pest control in push-pull farming systems, effective control strategies of the disease and the vector remain elus...
ABSTRACT The effect of three different concentrations of sucrose namely 2, 3 and 4% were investigated on the in vitro regeneration of embryo explants of Treculia africana Decne. on the media of Murashige and Skoog (MS) (1962) and Gamborg et al. (B5) (1968) respectively without any growth regulator. The experimental design was a 2 x 5 factorial in a completely randomized design with each treatment consisting of ten replicates. Results showed that while both media including control supported th...
ABSTRACT The evaluation of the molecular and phylogenetic diversity of Acha (Digitaria spp.) landraces of the Jos plateau and its environs, was carried out between 2012, 2013 and 2014.The phenotypic and genotypic characters of the different accessions showed that variability due to effect was more in genotype had more variability in genetic diversity for the morphological traits. Thirty accessions were collected from Tafawa Balewa Local Government Area(LGA) of Bauchi State; six LGAs of Plate...
Nature deposited in Nigeria several beneficial plant materials especially medicinal and aromatic plants (MAPs) for the treatment of ailments through herbal preparations, and for other culinary, traditional, medical and pharmaceutical uses. Preparation of natural medicine and production of herbal remedies by use of MAPs have proved to be a great alternative to the substandard production, cost and inaccessibility of synthetic orthodox medicines to rural dwellers. Despite the opportunities, ther...
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 have a consider...
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 fungal infectio...
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 it is ...
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 interaction...
ABSTRACT Soybean (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 ...
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...
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 ...
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...
