Abstract: Chili (Capsicum annuum L.) is an important spice, an integral part of many cuisines and widely used foods in the world. To assess the magnitude and extent of genetic variability, and association of agronomic traits among some chili accessions and varieties and their contributions to yield, a field experiment was conducted using twenty six accessions and four varieties during the off-season period from November 2016 to May 2017 under irrigation. The experiment was conducted using RC...
Abstract: Assessment of genetic variability in crop species is one of the major activities of plant breeding which helps to design breeding methods and/or selection of genotypes for further evaluation to meet the diversified goals. Therefore, this field experiment was conducted to assess the genetic variability in garlic genotypes, to determine association among traits and estimate the direct and indirect effects of traits on bulb yield. The field evaluation of 34 genotypes and 2 released va...
Abstract: Zinc and iron are among the essential plant nutrients required in relatively small quantities for plant growth. Deficiencies of Zn and Fe have been reported in soils of Tigray, Ethiopia. The deficiencies of Zn and Fe in the soil system affect both plant growth and the nutrient contents in the grain of cereals for human consumption. This study was developed to (1) assess the status of Zn and Fe in leaves of teff and bread wheat in relation to soil contents and properties in agro-eco...
Abstract: Medicinal plants have been used for centuries to treat diseases. This study was carried out to screen the phytochemical composition and evaluate the antibacterial activities of crude leaf extracts of Tanacetum parthenium (feverfew) against dental pathogenic bacteria. T. parthenium is a medicinal plant which belongs to the family Asteraceae. Mature leaves of this plant were collected from Haramaya University and were shade dried and ground to powder. The crude extracts were prepared...
Abstract: Faba bean (Vicia faba L.) is one of the earliest food legumes of the world used as source of high protein for human and animal consumption. In Guna wereda no studies were conducted on faba bean genetic variability and this study is designed to fill this gap. The study was designed to reveal the genetic variability and using phenotypic traits, fifteen accessions were laid out in a Randomized complete block designs (RCBD) with three replications. Each block consisted of 15 genotypes....
Abstract: Low soil fertility is a prominent factor for low agricultural productivity, whereby inorganic fertilizers have become important inputs to overcome the problem. In Ethiopia, different blended fertilizer types are used without clearly identifying the production limiting nutrient of a specific crop for a specific soil type. The present study was designed to identify the most yield limiting nutrients for sorghum on Leptosols through nutrient omission trials, which was conducted in 2021...
Abstract: Production of mungbean has been increasing in Ethiopia because of its high importance as a source of protein and foreign exchange earnings. Determination of appropriate plant density for the varieties of mungbean can increase its productivity. Therefore, an experiment was conducted to determine the effect of inter and intra row spacing on growth, yield components and yield of mungbean varieties under irrigation during 2016 cropping season at Gewane, Northeastern Ethiopia. The treat...
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...
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...
ABSTRACT Drought is a period of dryness especially when prolonged or when there is occurrence of persistent abnormal moisture deficiency, although drought is natural but it can be induced artificially under a controlled envirornnent. This study aimed at studying the effect of sodium selenite by studying their biochemical components and plant height. The seeds were collected at IIT A (INTERNATIONAL INSTITUTE OF TROPICAL AG RI CULTURE), Ibadan, Nigeria. Soil was collected and dried for 4 days,...
ABSTRACT Piper guineense (Schumach) has great potentials for economic exploration because of the proven use of its medicinal content in human health. The plant material is usually obtained from thick forests by women who have to walk long distances in the bush to reach it. A technique that improves its propagation and domestication, such as tissue culture, becomes necessary. This study was therefore initiated to develop a method for the mass propagation of Piper guineense seedlings using in...
