Abstract Bacterial wilt disease caused by Ralstonia solanacearum is one of the major diseases affecting solanum species, including cultivated African nightshade (Solanum nigrum L). The bacterial wilt (BW) management in the african nightshade vegetable presents a great challenge to production due to high survival rate of the pathogen in soil. Use of chemical application to control the disease is not eco-friendly. There is increasing demand for the crop as a vegetable and medicinal plant. Farm...
ABSTRACT This work was carried out to investigate the effects of pterocarpus mildbreadii seed on the HDL- level of albino rats.High density lipoprotein(HDL) is a fraction of cholesterol,which helps to transport cholesterol from peripheral of cell to the liver.High density lipoprotein is carried out to investigate cardio vascular diseases.Fresh oha seed (pterocarpus mildbreadii seed) was collected from Amokwe in udi local government Area Enugu state. They were dried at room temperature for abo...
ABSTRACT Tomato (Solanum lycopersicon L.) is a major horticultural crop with an estimated global production of over 153 million metric tons. It is the most important fruit vegetable and the second most widely cultivated crop in the world after potato, with a total production of about 141 million tons. In 2009, the average total yield in Ghana was 7.5 Mt ha-1 compared to the achievable yield of 15.0 Mt ha-1. The tomato industry in Ghana for the past decade has been bedevilled by a myriad of pr...
ABSTRACT African nightshade (Solanum scabrum Miller) is a vegetable, widely distributed throughout the tropics including East Africa. It is an important vegetable in Kenya but consumer demands have not been met due to low yields and partly due to attack by Aphis fabae Scopoli. The aphids cause serious damage through sucking plant cell sap from phloem leaving the plant weakened, dehydrated, stunted in growth and eventually under heavy infestation the leaves curl making the vegetables unattract...
ABSTRACT Pesticides bring a promise of higher yields of more food for the hungry and freedom from diseases spread by pests. However, pesticides are poisons and their residues do harm to human beings when the concentration is higher than the recommended maximum residue limits (MRLs). If a pesticide is left on vegetables, which are considered a cheaper source of natural nutrients, somebody could get sick or even get killed due to the poisoning. Therefore pesticide residues have become a high co...
ABSTRACT This project was carried out using acid activated coal from Enugu coal and the production of ve4getablew oil was monitored using spectrophotometer to measure the absorbance. It was also perform to check the suitability of activated Enugu coal as a bleaching agent for palm oil. The Enugu coal samples were collected, size reduced, carbonized and activated with acid (phosphoric Acid) before being used for the bleaching process. The bleaching process lasted for 40minutes and it was absor...
Abstract: Hot pepper is an important spice and vegetable crop in Assosa, western Ethiopia, however, its production is low due to several constraints of which low accessibility of improved varieties and poor cultural practices including soil fertility management. This research was conducted to asses the effect of blended NPS fertilizer on yield related and, green pod yield of hot pepper varieties and estimate cost-benefit of blended NPS fertilizer rates for hot pepper production. The research...
Abstract The adverse effects of climate change and increasing human population have put pressure on scarce water resources used in crop production. This consequently threatens the food and nutritional security of the growing human population. Vegetables are short season crops that are sensitive to water deficits during growth, leading to low productivity, poor marketability and reduced household incomes. Use of controlled irrigation in production of vegetables is considered a sustainable rou...
ABSTRACT A market- basket survey was carried out with the aim of determining the concentration levels of pesticides, in lettuce, garden eggs, pineapple and mango from some selected regions in Ghana and to assess the potential health risk associated with exposure to the pesticide residues from fruits and vegetables consumption. A total of 192 fresh samples of fruits and vegetables were randomly collected under normal purchase conditions from 12 major towns and cities in the three regions of Gh...
ABSTRACT Tomato (Lycopersicon esculentum) is one of the major vegetables grown in Kenya as a commercial crop. It is mainly grown in the open-field under both rain-fed and irrigation production systems. The crop has gained popularity as a cash crop due to declining land sizes as it can be grown on small-scale unlike traditional cash crops like coffee and tea. Since the crop is susceptible to diseases and weather conditions, the country does not have an all year round supply of the produce. Co...
ABSTRACT A non-weighing lysimeter was designed, fabricated, tested and installed at Arochukwu, Abia State, Nigeria, where the farmers who engage in dry season vegetable production do so with no knowledge of irrigation water requirements. This method tends to either over-irrigation or under-irrigation below the vegetable water requirements. Too much water can leach costly fertilizers to depths below the root zone, where both the water and fertilizer are permanently lost. Too little water ...
ABSTRACT A non-weighing lysimeter was designed, fabricated, tested and installed at Arochukwu, Abia State, Nigeria, where the farmers who engage in dry season vegetable production do so with no knowledge of irrigation water requirements. This method tends to either over-irrigation or under-irrigation below the vegetable water requirements. Too much water can leach costly fertilizers to depths below the root zone, where both the water and fertilizer are permanently lost. Too little water caus...
ABSTRACT: The interest in using Jatropha curcas L. (JCL) as a feedstock for the production of bio-diesel is rapidly growing. The properties of the crop and its oil have persuaded investors and policy makers to consider JCL as a substitute for fossil fuels to reduce greenhouse gas emissions. In this report, we gave an overview of the currently available information on the different process ste...
ABSTRACT Onion is one of the most important vegetable in Tanzania. However, yields are generally low weeds are among the major pests which reduce onion yields. A field experiment was conducted to assess the effectiveness of weed management practices in onion (Allium cepa L.) at Sokoine University of Agriculture, Horticulture unit during the dry season of October 2013 to February 2014. The experiment was laid down in a RCBD design with three replications. Three onions varieties (Red Bombay, Re...
ABSTRACT Ready-to-eat vegetables and fruits have intrinsic properties predisposing them to microbial contamination especially in the absenceof proper quality control procedures. Recently, the increased in consumables bio-burden manifested as the accumulation of potentialpathogenic microbes therein which triggered the food related ailments associated with morbidity and mortality cases. Evaluating themicrobial quality of such foods is therefore important. This study was aimed at evaluating the ...
