The aim of this study was to determine the microbial quality of legume and vegetable based foods and the hygienic practices of street venders who sold legume and vegetable based foods in Bahir Dar town from December 2013 to June 2014. Sixty food samples were collected from different locations Aerobic mesophilic, total coliforms, fecal coliforms and Staphylococcus aureus counts were determined using standard methods. Out of the total samples, 28.3%,33.3%,18.3% and 51.7% of the foods were above acceptable limit for aerobic mesophilic count, S. aureus, total coliforms and thermotolerant, respectively. While S.aureus and thermotolerant coliforms were not detected in 1(21.7%) and 29(48.3%) of the food samples, respectively. Only 7(11.7%) of the total sample was hazardous due to high mean count of S. aureus. There was no statistically significance differences in bacterial counts between legume and vegetable based food (p&gt;0.05). On the other hands, most of the water samples used to wash ready to eat foods and utensils in food preparation were contaminated and fell above WHO drinking water standards and are therefore doubtful quality. In addition, observational checklist shows majority of the handlers did not practice hand washing during food preparation and without reheating to serve prepared foods. Most of the ready-to-eat foods had acceptable levels of contamination; however can posing potential risks to consumers and it requires the local authority emphasize on educating the ready-to-eat food handlers on food and personal hygiene to ensure the hygienic standards and food safety. </em></p> Mohammed Tesfaye Copyright (c) 2019 International Journal For Research In Agricultural And Food Science (ISSN: 2208-2719) https://creativecommons.org/licenses/by-nc-nd/4.0 2019-08-29 2019-08-29 5 8 01 23 Evaluation of pot technology preservation techniques for tomato fruit in East Arsi, Ethiopia https://gnpublication.org/index.php/afs/article/view/1028 <p><em>The aim of this study was to</em> <em>extend the shelf life of tomato fruits using pot in pot technology. Exposure of tomato fruits to high temperatures during postharvest reduces their storage shelf life. Pot in pot technology differs from common air conditioning and refrigeration technologies in that it can provide effective cooling without the need for external energy source.</em> <em>Pot in pot technology has been found to be an efficient and economical means of reducing temperatures and increasing humidity in an enclosure where the humidity is comparatively low. Consequently, Pot in pot is a low cost technology for storage of fruits.</em> <em>Pot in pot reduced the inside storage temperature 18.19 <sup>o</sup>C, the fridge to 11.57<sup>o</sup>C while the average room temperature was 20.4 <sup>o</sup>C.&nbsp; The average inside storage relative humidity for pot in pot was 67.31%, fridge was 59.11% .while the average room relative humidity was 59.42 %. Highest pH value was recorded for tomatoes stored inside room temperature (4.71) followed by pot in pot (4.66), and least value was recorded for fridge storage method (4.43) on 12 days all at light red ripening stage. The total soluble solid(TSS) content of tomato stored at room temperature (1.02 <sup>o</sup>Brix) and inside fridge (1.01<sup>o</sup>Brix) was the same as tomatoes stored inside pot in pot (1.01<sup>o</sup>Brix) on 12 days of storage at light red ripening stage and the least TSS content was recorded inside fridge (1.01<sup>o</sup>Brix) after 19 days of storage. The total titrable acidity was highest on tomatoes stored inside pot in pot (0.12%) and fridge (0.15%) while minimum TTA was recorded for room temperature (0.14%) after 12 days all at ripening stage.</em></p> Melaku Tafese Awulachew Copyright (c) 2019 International Journal For Research In Agricultural And Food Science (ISSN: 2208-2719) https://creativecommons.org/licenses/by-nc-nd/4.0 2019-08-29 2019-08-29 5 8 24 31 The Concepts and Types of Plant Growth Hormones and their role in Field Crop Production https://gnpublication.org/index.php/afs/article/view/1054 <p><a name="_Toc531173959"></a><em>This paper is intended to revise those findings in the area of plant growth hormones; concepts, type and their role in field crop production for the better understanding of previous and current research findings. The plant hormones are defined as organic compounds which regulate plant physiological process regardless of whether these compounds are naturally occurring and/or synthetic; stimulating and/or inhibitory; local activators or substances which act at a distance from the place where they are formed. Hormones are chemical signals that are produced in one part of the body /tissue and transported to other parts of the plant bind to a specific receptor and trigger responses in the target cell and tissue. Plant development was thought to be regulated by only five types of hormones; auxins, gibberellins, cytokinins, abscisic acid, and ethylene. However, there is no compelling evidence that has a wide range of morphological effects on plant development. Current study indicate that plant growth hormones has play a significant role </em><em>in the growth, physiological, biochemical, quality and yield characteristics of pulse crops which include length, fresh and dry weight of root, leaf number, leaf area, leaf area index (LAI), net assimilation rate (NAR), chlorophyll content, photosynthesis, nitrate reductase activity (NR), carbonic anhydrase activity (CA), nutrient accumulation, nitrogen, phosphorus and potassium contents, protein and carbohydrate content and various other growth, yield and quality parameters.. So the present review indicates that the process of growth and development, in addition to the yield and quality of plants is highly affected by the plant growth hormones and plant growth regulators. </em><em>Finally, the objective of this term paper is to point out those research results in the area of plant growth hormones; their major classifications and role in field crop production through the review of different papers in this area.</em></p> Addis Tadesse Tekle Copyright (c) 2019 International Journal For Research In Agricultural And Food Science (ISSN: 2208-2719) https://creativecommons.org/licenses/by-nc-nd/4.0 2019-08-29 2019-08-29 5 8 32 56 Importance of Seed Anthracnose on Beans https://gnpublication.org/index.php/afs/article/view/1074 <p><em>Disease infected seed can have reduced storability, decreased germination, loss of seed weight and reduced meal and oil quality. Optimum storage conditions to limit fungal growth includes: Seed free from fungi or other pests, Clean seed without organic or other waste material, Less than 12% moisture, and Cool uniform storage temperature.</em> <em>Management options to minimize diseases on seed:</em> <em>Start with clean seed (pathogen free) and use resistant varieties when available.</em> <em>Fungicide options Seed treatments can help reduced seed to seedling disease transfer.</em> <em>Foliar fungicides can help reduced the risk to pod and seed infection by some fungi. Tillage and crop rotation – bury the inoculum from disease-infested residue and further reduced the inoculum by planting a non-host the next season.</em> <em>When at threshold levels, control pests, such as bean leaf beetle, and other insects that injure the pod, opening the door to fungal infection. Infected seed also can introduce new races of the pathogen into different geographic regions. Anthracnose can move into new fields with infected seed, which give rise to diseased seedlings that act as a source of inoculums of the anthracnose fungus that is spread to adjacent plants by splashing rain. Sowing infected seed also results in poorer emergence and reduced seedling vigor. Seed producers need to maintain very high standards of disease control in order to maximize yield and provide bean producers with high quality, disease-free seed. Growers should have seed samples tested to ensure they are not infected. The use of disease-free seed is a critical component of any strategy to prevent losses caused by this disease.</em></p> Melkam Anteneh Alemu Copyright (c) 2019 International Journal For Research In Agricultural And Food Science (ISSN: 2208-2719) https://creativecommons.org/licenses/by-nc-nd/4.0 2019-08-29 2019-08-29 5 8 27 65 Seed Germination and Seedling Growth Potential of Haricot bean under Laboratory Conditions https://gnpublication.org/index.php/afs/article/view/1081 <p><em>Haricot bean (Phaseolus vulgaris</em> L<em>.) differ in their low temperature tolerance regarding growth and yield. Varieties tolerant to low temperature during germination and carriers of the seed quality standards are needed for the success of the crop. Ten seeds were placed per petridish uniformly and covered with lid to prevent loss of moisture through evaporation. The seeds were allowed to germinate for 10 days at room temperature. The germination percentage was recorded on the 10th day. Germination was considered to have occurred when radicles attained a length of 2 mm. The objectives of this study were to evaluate the germination of bean seedlings under controlled environment with in laboratory conditions. Trial were conducted with dry bean seed in moderate or controlled environment. The seedling, shoot length for varieties Awash-2 a little bit different than other two moreover seedling fresh and dry weights all are equal values. Morpho-agronomic data were used to evaluate the phenotypic performance of the different varieties before the seed or seedlings going on the field.</em></p> Melkam Anteneh Alemu Copyright (c) 2019 International Journal For Research In Agricultural And Food Science (ISSN: 2208-2719) https://creativecommons.org/licenses/by-nc-nd/4.0 2019-08-29 2019-08-29 5 8 66 70 APPLICATION OF REGRESSION TREE IN MODELLING AND MAPPING OF CATION EXCHANGE CAPACITY OF SOILS IN AKWA IBOM STATE, NIGERIA https://gnpublication.org/index.php/afs/article/view/960 <p>&nbsp;Regression tree &nbsp;&nbsp;was used in modelling and mapping cation exchange capacity of soils in Akwa Ibom State, Nigeria.The aim was to provide an alternative techinque of estimating ECEC from more readily available soil data and map the distribution for site-specific soil management. The study area (Akwa Ibom State) was grouped into four major mapping units based on parent materials, namely:&nbsp; coastal plain sand, sandstone, shale and beach ridge sand. Each parent material (major mapping unit) was subdivided into four commonly practice landuse types/soil management systems namely homestead or compound farmland, oil palm plantation, secondary forest of 3 years and above and cultivated farmland.&nbsp; In each landuse type/soil management system, mini- soil profile pit was dug to a depth of 100cm at representative location. Soil samples were collected from designated depths of 0-20, 20-60 and 60-100 cm. A total of 144 samples were generated for laboratry analysis. The study revealed that ECEC can be predicted using soil organic carbon, clay, silt and soil pH in the study area. The results of independent variable importance to the model showed that organic carbon was the most significant predictor of ECEC with 22.1 % contribution, followed by clay with 17.3 %, followed by silt with 8.5% while soil pH was the least predictor of ECEC with 0.8% contribution in the study area. Based on the model, organic carbon content predicted ECEC of 32.4 cmol/kg in sandstone soil while organic carbon in combination with clay predicted ECEC of 40.24 cmol/kg in soils developed from shale parent material. In coastal plain sand soils, organic carbon in combination with clay and silt predicted ECEC of 24.3 cmol/kg. In beach ridge sand soils, organic carbon in combination with clay and silt predicted ECEC of 17.8 cmol/kg. The model showed that organic carbon content was the only significant predictor of ECEC in sandstone soils while organic carbon in combination with clay made significant prediction of ECEC in shale parent material. In coastal plain sand and beach ridge sand soils, Organic carbon in combination with clay and silt made significant prediction of ECEC. In the application of the model, independent variables included in the final model and measured in the same unit should be used.</p> Udeme Akpan Uwah I.D. Nkannga, N.A.
