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...

ABSTRACT Sunflower (He!ianthus annuusL.) occupies the fourth position among vegetable oilseeds after soybean, oil palm and canola in the world.A field experiment was conducted on a farm in Ado Ekiti South-West Nigeria (Latitude7' 37'23 N and longitude 5' 13' l 5E with l 440 ft above sea level) between December 2017 and April 2018 to evaluate the performance of two Sunflower varieties (SAMSUN I and SAMSUN 2) as affected by the geographical location and abiotic factors. Soil analysis was carri...
ABSTRACTS Cassava is vulnerable to a broad range of diseases caused by viruses. Among them, cassava mosaic disease (CMD) is the most severe and widespread, limiting production of the crop in subSaharan Africa.CMD-affected cassava plants produce few or no tubers depending on the severity of the disease and the age of the plant at the time of infection. CMD is one of the major constraints for cassava production in Nigeria. This study was therefore undertaken to determine the extent of CMD infe...
ABSTRACT This investigation is to determine the physiological basis of water deficit stress in pearl millet, (Pennisetum glaucum) and maize (Zea mays). Crops were grouped into two categories, each representing a treatment and replicated 3 times. Category (1) which serve as the control received 100ml of water every 2 days t)1roughout the experimental period. Category (2) received 100ml of water every 2 days for 6 weeks before subjecting them to simulated drought. Physiological parameters eval...
ABSTRACT Bambara nut (Vigna subterranea (L.) Verdc.) is an indigenous legume crop in Kenya. Fusarium oxysporum f.sp voandzeia is a destructive fungal pathogen affecting Bambara nut in Kenya. An experiment was carried out in the green house and field to determine the incidence and severity of Fusarium wilt on local landraces and evaluate its management using goat farm yard manure (FYM). The field experiment was carried out in Busia County, where four villages (Bufisi, Bukati, Madola and Butun...
ABSTRACT Root knot diseases are known to attack many crops especially legumes such as chickpea. Losses due to root knot nematodes (Meloidogyne spp.) in chickpea have been approximated at 13.7% of yield loss which translates to loss of billions of shillings annually. Four main Meloidogyne species; M. hapla, M. javanica, M. arenaria and M. incognita attack chickpeas. Experiments were conducted in the greenhouse to characterise, identify and control Meloidogyne spp. causing root knot disease in...
This study was conducted in both laboratories of plant pathology and tissue culture in College of Agricultural Studies, Sudan University Science and Technology Nine cultivars of Sorghum bicolor collected from Gadarif area were tested for the presence of seed borne fungi. The cultivars were Mugudahmer, Wadahmed, Wadakar. Arfaagadamac, Hageen, Tetron, Dabar, Fatarita and Tabet. Seed health testing included dry inspection in which the seeds were divided into healthy, broken and infected....
ABSTRACT Commercial production of Agaricus bisporus is dependent upon a substrate prepared by composting. Traditional composting is associated with a number of environmental problems such as the emission of offensive odors and waste water run-off during handling. In addition, after the production of a crop of mushrooms, there is the problem of disposal of spent mushroom substrate (SMS). Thus, preparation of a suitable substrate for mushroom production without the generation of offensive odor...
Abstract Both growth chamber and field experiments were conducted to study the influence of resistant tomato cultivars and applications of Vorlex (DD MENCS) on the population dynamics of root knot nematode species and growth and yield of subsequent crops of a susceptible tomato 3 3 cultivar. Four initial M. incognita inoculum densities (10 , 5 x 10 , 104 and 105 eggs/500 orT of soil) and two initial M. hapla inoculum o o o ^ densities (10 and 5 x 10 eggs/500 cm of soil) were used. Two resist...
ABSTRACT Bacillus anthracis, a soil-borne pathogen, causes the deadly zoonotic disease anthrax. Anthrax outbreaks occur frequently in Etosha National Park (ENP). ENP has nine major soil types and a distinct rainfall gradient decreasing from east to west. The sporulation success of B. anthracis is believed to be influenced by soil type, but the influence of soil type and site along a rainfall gradient on the persistence of B. anthracis in the soil is unknown. The present study investigated th...
ABSTRACT A new revision of the genus Pentatrichia Klatt is presented here. Morphological data from previously described taxa: P. alata S.Moore, P. avasmontana Merxm., P. petrosa Klatt and P. rehmii (Merxm.) Marxism. were subjected to both univariate and multivariate statistical methods. Both herbarium material and voucher specimens collected during fieldwork were examined. Morphological character data were analysed by Unweighted Pair-group Method Arithmetic Average (UPGMA) clustering algorit...
ABSTRACT Marama bean (Tylosema esculentum) is a highly nutritious plant and is currently regarded as a prospective crop for the future in arid zone agri-ecologies of the world. Starch is a major storage component in higher plants and in marama bean it’s mostly found stored in the tuber. Starch is used in both food and non-food industries. Starch biosynthesis involves groups of committed enzymes. Aims of the present study were to determine the physicochemical and pasting properties of nativ...
