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...
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...
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 This study was conducted to ascertain drought tolerance in sorghum genotypes. Seedlings of locally cultivated sorghum were screened for drought tolerance by assessing percentage relative water content (R WC) after progressive water deficit. Plant biomass, root/shoot ratio, tolerance index, relative water content (RWC) were measured during harvest. Malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), chlorophyll and praline content were quantified....
Assessment Of Arginase In The Mesocarp Of Ripe And Unripe Tomatoes (Solanum Lycopersicum L.)
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...
